Frequency Selection Guide

Radio frequencies used for wireless communication in most countries including the United States are under strict control and regulations. These regulations specify which devises can be used at what frequency and tend to limit interference within the frequency bands.

To ensure consistant reliable frequency availability and to minimize the intereference that might occur the user can choose frequency bands between 470 and 489 MHZ or 514 and 542 MHZ.

For the user’s convenience, preset frequency groups have been created to minimize intermodulation distortion. When using multiple receivers and transmitters each system must use a seperate and different channel. Grouping the receivers and then using seperate channels on the transmitters will provide the best frequency use and distribution.

When using up to 3 units (max of 6 channels) in the same frequency range, the wireless microphone system does not require an antenna combiner under normal conditions. If using 4 to 7 units (8 to 14 channels) the use of an approved antenna combiner is highly recommended.

For assistance in selecting the best operating frequency range in your zipcode, you may call Airwave Support at 305-891-7399

Navigating The Menu On The Receiver (AT-4200)

1. Hold SET button for 3 seconds to unlock display.
2. Press SET button again and you will scroll through the different settings on the display. Volume (default), GR Group, CH Channel, SQL Squelch, RF (Radio Frequency) Range, & Gain.
3. Selected setting will flash.
4. Press up and down buttons to change selection values.
5. System saves settings and auto locks when idle for 10 seconds.

Syncing Transmitters (u-41 Handheld or U-42 Body Pack)

1. Turn ON transmitter and lower or remove its battery cover. Locate its IR transmission window.
2. Press the ASC button on receiver to sync its setting to the transmitter. Receiver will transmit selected group, channel, and gain adjustments for approximately 25 seconds.
3. Hold up the IR window of the transmitter to the IR window of the receiver about 3-6” apart during the 25 second IR transmission cycle. NOTE*** On units manufactured after 2021, the ASC button acts as an ON / OFF toggle. Long pressing the button will not activate the syncing sequence. Lightly press the ASC button and the IR Window Icon will flash during IR transmission.
4. Verify matching channels and settings between the transmitter and receiver. The RF meter of the receiver should have full bars across the screen with matching frequency. The AF meter should display bars when you speak into the transmitter.

Selecting A Clear Channel

1. Turn ON the receiver and keep the transmitter OFF.
2. On the top of the display you will see 2 metered bars, RF (Radio Frequency Indicator) and AF (Audio Frequency). Goal is to select a channel without RF and AF activity during selection process.
3. Groups and channels can be selected manually following the instructions above.
4. You can use AUTO function to select best available frequency within the selected group. Press the AUTO button after unlocking the system (no icons flashing). AUTO scan can take up to 30 seconds.
5. Turn on transmitter and sync it to the receiver. See instructions for “Syncing Transmitters”.
6. For multiple systems, repeat step 3-5 for each transmitter. Turn onone transmitter at a time to make sure there’s no interference on any of the other receivers.

Tips For Best Performance

1. If experiencing interference or signal dropouts, search and change to another channel using instructions above.
2. If signal dropouts persist, you may increase the transmitter signal strength in settings which should give the system longer range, at a slightly greater risk of experiencing interference.
3. If Interference is the persistent, try increasing the SQL (Squelch) set tings. Increasing the Squelch will help ignore audible artifacts /in terference at the slight cost of transmission range. Experiment with adjusting the squelch and transmission signal strength for optimal performance.
4. If issues persist, please contact the Airwave Technologies support number or email so we may assist with troubleshooting and frequency selections.

Important Safety Instructions

Transmitter and antenna should remain in line of sight for best signal reception.

Do not place the receiver in close proximity to a metal surface or near any digital device.

Receiver should be placed 3′ off the ground and have space surrounding to ventilate.

Ventilation holes should not be covered.

Two-way radios can interfere with any audio transmission. Insure the transmitter and receiver are far from these devices to eliminate potential sources of interference.

Receiver should not be placed in direct sunlight and should be kept away from any water sources or open flame.

Nominal operating temperature is -5° C ~ +50° C (23° F ~ 122°F)

Troubleshooting

onConfirm batteries are inserted correctly +/­Confirm batteries in transmitter are charged
Receiver Power Indicator Off| Confirm AC power is connected to receiver via power jack.Confirm AC power supply is normalConfirm Voltage on power supply is normal
Receiver RF Indicator illuminated| Adjust high receiver volume controlAdjust high transmitter gain switch setting Check receiver / amplifier / mixer connections
Receiver Power Indicator Off
Receiver RF Indicator illuminated| Ensure receiver is away from metal surfaces. Ensure space between transmitter and receiver is free of obstacles.Verify transmitter and receiver are using the same frequency.
