SYSTEM OPERATION

U-800 RECEIVER

Button Function
The POWER ON Button (1) is used to power receiver ON or OFF. When the power button is pressed, the POWER LED (2) and the white backlight on the LCD DISPLAY (5) will light up indicating the receiver is ready. Press the Power button again to turn off the receiver. The power LED and the backlight on the LCD will be off indicating the receiver is off. At power-off the U-800 receiver will store the last settings entered and re-display them at power-on. It can be reprogrammed to any new Group/Channel, or Mute level. The default factory setting is Group 11, Channel 01 and Mute 0 on the first LCD menu screen.
The UP BUTTON (16) is pressed one step at a time to SCAN, IR or to increase
GROUP, CHANNEL, MUTE by one level each time
The DOWN BUTTON (17) is pressed one step at a time to decrease GROUP, CHANNEL, MUTE by one level each time
The MENU BUTTON (18) is pressed one step at a time for Auto Scan Frequency or to Automatic GR/CH ASC™ Sync, or if pressed repeatedly the LCD DISPLAY (5) menu will cycle through the following screens.

During manual programming, press the MENU BUTTON (18) to confirm the selection and advance to the next menu before the Auto Programming Function takes over after 5 sec.

Rack Mounting the Receiver
There are 2 options available for rack mounting the U-800 receiver: singly or side by-side with another U-800 receiver.
a. Single mounting: Remove the receiver SIDE MOUNT CLIP (24) from each side of the receiver (as shown) and slide in the optional ERM-12 RACK EARS (25).
b. Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (24) from both U-800 receivers join the two receivers with the EJC-3 JOINING CLIP (26) and attach the ERM-22 RACK EARS (27) as shown.
(Note: Do not mount the receiver in a rack directly above an amplifier or other source of high heat — this could degrade the performance of the U-800. Always ensure adequate airflow and heat dissipation in any rack configuration.)

Powering the Receiver
Plug the AC/DC ADAPTER (23) provided into the DC INPUT JACK (20) on the back of the receiver. Then plug the power supply into an AC outlet. (Note: Any 22V DC source with 400mA capability can also be used.) Press the POWER SWITCH (1) once to turn on the receiver. The POWER ON LED (2) and the LCD DISPLAY (5) will now light and the receiver is operational.

Adjusting Antennas
The U-800 has two permanently attached, flexible elbow ANTENNAS (3) for diversity reception. Unfold and rotate these antennas to operate the receiver. The optimal positions of the antennas are flared 45° out from the receiver sides and 90° from each other. For maximum range, it is always best to maintain a line-of-sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible.

Adjusting the Mute Level/ RF Squelch
The MUTE LEVEL/RF SQUELCH (13) can be changed anytime during the mainscreen display to quiet the receiver in high noise environment condition. The control ranges are from level 0 to level 5. The level should be adjusted to a lower number for the minimum RF squelch setting at which the RF INDICATOR (8) will remain on while your transmitter is in normal use, up to the maximum operating range anticipated in use for your application. However, in areas of high RF activity, the squelch control may need to be adjusted to a higher number. If the transmitter is off and the receiver’s signal RF INDICATOR (8) or the diversity A or B INDICATOR (9) flickers or stays on continuously, the squelch should be adjusted to a higher number to stop the flickering. Be careful not to select too high a number setting as this may reduce the operating range to below what is needed. A range walk test will help in selecting the proper level. If the range is not critical, note that a higher level (maximum squelch) setting will also yield a quieter mute function, which might be desired in certain applications. The squelch level is factory preset at maximum sensitivity and operating range (i.e. level 0 for minimum squelch level—maximum usable range).

Note: For easier intuitive operation, the MIN and MAX indications for this control refer to the minimum and maximum operating range settings, not to the actual mute levels selected, which are the opposite as per above.

Keyboard/Buttons Lock Function
Use keyboard/Buttons Lock Function to lock or unlock the receiver controls, preventing accidental adjustment during use: You can push and hold MENU BUTTON (18), then push UP BUTTON (16) to lock; push and hold MENU BUTTON (18), then push UP BUTTON (16) again to unlock. The Keyboard/Buttons must be unlocked before you can make a selection: AUTO SCAN, Group/Channel or MUTE levels.

Audio Level and Peak LED Indicator
The U-800 receiver has a 5 bar AF LCD (7) display that typically shows a few bars indicating normal level audio signal from the transmitter. Occasional flickering of the fifth AF LCD (peak level) on loud inputs to the transmitter is normal. If the AF LCD lights up full bars continuously decrease the input audio level to the transmitter or overload distortion may result.
Connecting the Audio Output
The U-800 receiver has two type of outputs available, an adjustable level ¼” UNBALANCED LINE OUT (19) and a fixed level MIC out BALANCED MIC OUT XLR JACK (22). The ¼” unbalanced line out is controlled by the VOLUME CONTROL (21).

For unbalanced line output connection, plug an audio cable with a ¼” mono (Tip/Sleeve) plug into the Unbalanced Line Out jack and plug the other end into your mixing board or amplifier. Adjusting the Volume control will increase or decrease the audio level at the ¼” Unbalanced Line Out only.

(Note: When using the UB-800 instrument transmitter system, connect the Unbalanced Line Out directly to your instrument amp or preamp. At maximum receiver volume setting, the system output is approximately +4dB higher than a direct cord-to-amp connection.)

For balanced Output connection, plug an audio cable with an XLR connector into the Balanced Mic Out XLR Jack socket and plug the other end into your mixing board or amplifier and control the audio levels from there. Both the ¼” Unbalanced Line Out and the XLR Balanced Mic Out can be used at the same time to connect to your mixing board, effect, or amplifier. Please follow below drawing for the audio cable/connector wiring.

Your U-800 receiver is now operational and ready to use. Proceed to the following instructions for the UH-800 handheld microphone transmitter or UB-800 bodypack transmitter included with your system.

Note: As when making any connection, make sure the amplifier or mixing board volume is at the minimum level before plugging in the receiver to avoid possible sound system damage.

Note: : Only one transmitter can be used with one receiver. It is not possible to use two transmitters on the same frequency and mix the output of these transmitters into one wireless receiver.

Programming the U-800 to the Selected Group/Channel (frequency)
The Receiver must be programmed for a Group/Channel (frequency) first then automatic synchronization using the IR ASC™ Sync function to the transmitter. For system
set up procedures, see next section “6. Selecting Group/Channel, IR Programming and Simultaneous Multichannel Operation”

Programming the UB-800 to the Selected Group/Channel (frequency) The transmitter must be programmed to the same frequency as selected for the receiver via automatic synchronization using the IR ASC™ Sync function. It cannot be programmed on the transmitter itself. See next section “6. Selecting Group/Channel, IR Programming and Simultaneous Multichannel Operation”.

SELECTING GROUP/CHANNEL, IR PROGRAMMING AND SIMULTANEOUS MULTICHANNEL

OPERATION

Note: Note: The transmitter should be turned ON and ready for the IR communications with the receiver IR receptor for the following process.
Note: If no button is pressed within the five seconds period during a selection, the program is terminated and the process needs to be repeated.
Note: For normal operation, the transmitter should have the same channel as displayed on the receiver.

Choosing Group/Channel for the System
The receiver offers a choice of 15 groups: 10 that are Factory PRESET (Group 11 to 1A) and 5 that are User SELECTABLE (Group 1B to 1F). If the Factory PRESET Group mode is chosen, only a limited numbers of channels are available in these groups. For most convenient setup, each of these groups offers from 3 to 14 channels (depending on group selected) to choose from that are factory preset for simultaneous multichannel operation compatibility and are retained in memory after the receiver is powered off. For the User SELECTABLE Group 1B- 1F mode, a letter “U” will lit up on the LCD DISPLAY (5) instead of the CHANNEL (12) number as in the Factory PRESET Groups. Each User SELECTABLE Group has 800 channels to choose from either by manually selecting a channel or using the Auto-Scan in 1MHz segment increments at a time within the frequency band and they are retained in memory after receiver is powered off. This facilitates easy setup by enabling quick selection of stored channels for any group, i.e, selecting any group will automatically display the last channel selected for that group. See section “11. U-800 Frequency Lists” for available channels in each group. The previous group and channel used is stored in memory automatically when receiver and transmitter are turned off after operation. Selecting a different group on the receiver in subsequent use will display a different channel as previously selected for that group, however, the transmitter will need again to be sync’ed to that new frequency to complete the system setup for operation.

Receiver ASC/IR Sync GR/CH (Frequency)
If different frequencies than previously stored in both the receiver and transmitter memories are needed, there are three ways to program the receiver and then sync the selected Group/Channel to the transmitter: One-Touch Automatic ASC™/ Auto Sync receiver to transmitter, manual SCAN for Group/Channel, or manual select Group/Channel from the Factory Preset or User Selectable channel. Place the transmitter’s IR RECEPTOR SENSOR WINDOW (37, 44) 6-12” away from the receiver’s IR WINDOW (4) before starting the following steps.

• For One-Touch channel Autoscan and Automatic ASC™/Auto Sync from the receiver to the transmitter, press the MENU BUTTON (18) once, wait for about 5 seconds, the receiver will start process automatically with no further user action required. A running bar in a clockwise direction on the LCD DISPLAY (5) shows the scanning process which normally takes about two seconds. When it finds an interference-free channel, the receiver stores the channel for use, and it will begin ASC™ sync IR download of the selected channel to the transmitter automatically.
• To manually scan the selected Group/Channel, press the MENU BUTTON (18) twice for AUTOSCAN menu, press UP BUTTON (16) once and it will start scanning. A running bar in a clockwise direction shows the scanning process, which normally takes about 2 seconds. When it finds an interference-free channel, it will display and store the frequency/channel for use. It can be rescanned again for a new frequency by pressing the UP button or pressing the MENU BUTTON twice to IR MENU (IR icon will lit up for IR function), then pressing UP BUTTON to start IR programming.
• To manually select Group/Channel press the MENU BUTTON (18) once for GROUP (11) selection for Factory PRESET Group 11 to 1A mode or User SELECTABLE Group 1B to 1F mode. Use the UP/DOWN Buttons to change the group. After selecting a group, press the MENU BUTTON twice for channel selection menu.
  Use the UP/DOWN Buttons to change the channels (frequencies) that are available in each group. [Note: for Group11 to 1A, the CH (12) display will indicate the channel number chosen, and for Group 1B to 1F only the letter “U” and the frequency chosen will be displayed. See section “11. U-800 Frequency Lists” for available channels in each group]. After finishing channel selection, press the MENU BUTTON once or wait a few seconds for IR MENU, and then press UP BUTTON to start IR programming.

This completes the GP/CH (frequency) programming. The next section outlines the procedure for sync’ing the receiver’s programmed channel to the transmitter.

Receiver/Transmitter ASC™ IR Sync Manual Programming
To manually program the pre-selected Group/Channel (frequency) from the receiver to the transmitter, place the transmitter’s IR RECEPTOR SENSOR WINDOW (37, 44) 6-12” away from the receiver’s IR WINDOW (4). Press the MENU BUTTON (18) four times to the IR Screen Display and then press the UP BUTTON (16) to start IR programming. The flashing IR INDICATOR (10) icon indicates IR transmission is in progress. When the synchronization is completed successfully (usually in less than 2 seconds), the RF INDICATOR (8) and the diversity A or B INDICATOR (9) on the receiver will display, indicating that the IR linking is completed. The LCD DISPLAY SCREEN (5) will show the selected channel. If the UP button is not pressed during the two seconds of active data transfer, the IR INDICATOR (10) will not flash, the LCD Display will revert to the main menu, the receiver will not link to the transmitter, and the transmitter’s previously programmed channel remains unchanged.

Instructions for Setup of Simultaneous Multichannel Operation
This U-800 receiver is capable of finding an open channel with its autoscan capability. This built-in feature is a quick, convenient way to set up many wireless systems at the same location for simultaneous multichannel operation.
If you are using multiple transmitters at the same location, set up the first transmitter and leave it ON and keep 10 feet away from the receivers and 1 foot away from transmitter to transmitter. This avoids possible duplicate selection of the same channel as already selected for the first receiver. Then start the autoscan function on the second receiver.

Repeat this procedure for all receiver/transmitters to be used in your system. Finally with all the transmitters ON, perform a range walk test in the location these systems will be used in to check for potential crosstalk interference in this application.

If you are not satisfied with any of the channels scanned, repeat the autoscan procedure for that receiver again anytime for finding another free channel.

This process can be simplified if you select channels within Factory SELECTED Groups 11 to1A, as the channels within those groups are mutually compatible (unless there is outside interference on any of the selected frequencies). If there is any such interference in your location, select as many channels as you can using these 10 groups and then select additional open channels as needed (depending on number of systems to be operated simultaneously) from Groups 1B to 1F. As noted above all these groups will retain in memory the previously selected channels for that group for easy setup subsequently in that same location.

CAUTIONS AND TROUBLESHOOTING

Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.
Please also note the pickup pattern characteristics of the microphone selected.
Unidirectional microphones are more resistant to feedback. However, they pick up sound sources best that are directly in front of the microphone. Also, mics that are farther from the sound source (such as a handheld) require more acoustic gain and thus are also more prone to feedback than close-source mics.

No or Low Audio
If you are not getting audio through the system, carefully re-check all setups.
Especially note that the receiver and transmitter must be set to operate on the same RF channel. Also confirm that the transmitter’s AUDIO MUTE (36, 40) is not in the OFF position. The receiver’s UNBALANCED LINE OUT (19) is adjustable so make sure the VOLUME CONTROL (21) is set properly.

RF Interference and Finding Open Channels
The FCC mandates the following information be provided to all end users of this equipment:

Consumer Alert
Most users do not need a license to operate this wireless microphone system.
Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50mW); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change.

For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit : www.fcc.gov/cgb/consumerfacts/wirelessmic_factsheet.html.

If you encounter slight receiving interference when the transmitter is far from the receiver (from other than an operating TV station on the same frequency), it can often be overcome by adjusting the receiver‘s MUTE LEVEL/SQUELCH (13)—see Adjusting the Mute Level / RFSquelch.

If receiving interference on a selected channel with the transmitter off, or if you encounter interferences in operating multiple U-800 systems simultaneously at the same location see: “6. Selecting Group/Channel, IR Programming and Simultaneous Multichannel Operation” for proper procedures for reprogramming system(s) for open channels.

MISCELLANEOUS TIPS

• The receiver antennas should be kept away from any metal surfaces whenever possible as they can reflect away or shield the incoming RF signal.
• If the receiver’s volume control is set too high, it may overdrive the input of the attached audio mixer, causing distortion. Conversely, if the output is set too low, the overall signal-to-noise ratio of the system may be reduced, causing noticeable hiss.

If such noise occurs, adjust the output level of the receiver so that highest sound pressure level going into the microphone transmitter causes no input overload in the mixer, but permits the mixer level control to operate in the normal range (not too high and not too low). This provides the optimal signal- to-noise for the entire system.

• Before inserting the batteries, ensure that they are inserted with the correct polarity.
• Before operation, confirm that the receiver and associated transmitter are tuned to the same frequency group and channel number.
• After making a receiver channel change, ensure that the corresponding change is also made on the matching transmitter.
• Use only new alkaline or fully recharged NiMH batteries. Do not use “general purpose” carbon batteries. When batteries are weak, replace all the batteries at the same time. Do not mix new and old batteries.
• Position the receiver so that it has the least possible obstructions between it and the transmitter. Line-of-sight is best!
• During operation, the transmitter and the receiver should be as close as possible for optimum results but never closer than 3 ft. (1 m) as that may overload the receiver’s input circuitry and cause noises.
• If rack mounting the receiver, keep away from heat sources such as amps by allowing enough space between them for adequate ventilation.
• For the best operation, the receiver should be placed at least 3 ft. (1 m) above the ground and 3 ft. (1 m) away from a wall or metal surface. The transmitter should also be at least 3 ft. (1 m) from the receiver. Keep antennas away from noise sources such as motors, automobiles, neon lights, signal processors, computers, as well as large metal objects.
• A receiver cannot receive signals from two or more transmitters simultaneously.
• Turn the transmitter off when it is not in use. For longest life, remove the batteries if the unit is not to be used for a long period as the transmitters draw a tiny residual current to maintain the programmed settings, even when turned off. Also, since batteries installed for a long time can sometimes corrode and/or leak, causing damage, it is generally recommended that batteries be removed whenever the transmitters are not being used.
• When using the bodypack for instrument use: Scratchy noises can sometimes occur when an electric guitar with dirty pots or connections is used with a wireless system.
  Therefore, the supplied capacitor provides first-order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still produce scratchy noise, we suggest these steps to eliminate problems:

1. Make sure all guitar volume and tone pots are clean and all contacts are solid. This is very important.
2. Solder a 47pF capacitor across the pot to ground terminal of the guitar’s volume and tone pots to provide extra filtering.

ONE YEAR LIMITED WARRANTY

Nady Systems, Inc. warrants to the original consumer purchaser that the unit is free from any defects in material or workmanship for a period of one year from the date of original retail purchase. If any such defect is discovered within the warranty period, Nady Systems, Inc. will repair or replace the unit free of charge, subject to verification of the defect or malfunction upon return to Nady Systems. Please do not return your Nady product to the store where it was purchased as Nady Systems handles your warranty service directly.

To the extent permitted by law, any applicable implied warranties, including warranties of merchantability and fitness are hereby limited to one year from the date of purchase. Consequential or incidental damages resulting from a breach of any applicable express or implied warranties are hereby excluded. This warranty is in lieu of all other agreements and warranties, general or special, express or implied and no representative or person including a Nady dealer, agent, or employee is authorized to assume for us any other liability in connection with the sale or use of this Nady Systems’ product.
Whereas some states do not allow limitations on how long implied warranties last, and do not allow exclusion of incidental or consequential damages, the above limitations and exclusions may not apply to you. This warranty gives you specific legal rights and you may also have other rights which may vary from state to state.

This warranty is subject to the following conditions:

1. This system must have been purchased from an authorized Nady dealer and all warranty service must be performed by Nady’s service department. Any service not performed by Nady will automatically void this warranty.
2. Items not covered: physical damage resulting from improper handling of the unit in transit from the factory by the shipper (Nady Systems is not responsible for such damage and all such claims must be made against the shipping company by the consignee); defects caused by normal wear of the product (expendable parts are typically connectors, cables, potentiometers, switches and similar components); damage or defects caused by abuse, neglect, accident, failure to connect or operate the unit in any way that does not comply with applicable technical or safety regulations, or improper repair, excessive heat or humidity, alteration or unreasonable use of the unit, causing cracks, broken cases/housings or parts; damage caused by leaking batteries; finish or appearance items; items damaged in shipment en route to Nady Systems, Inc. for repair. The warranty is null and void if any Nady serial number has been removed or defaced.
