INSTALLATION

Contents Unpack and inspect your Stryker SR-655HPC for missing or damaged Components.

Location
Plan the location of the transceiver and microphone brackets before starling the installation. Select a location that is convenient for operation and does not interfere with the driver or passengers in the vehicle. In automobiles, the transceiver is usually mounted below the dash panel, with the microphone bracket beside it. Mounting Your mobile radio is supplied with a universal mounting bracket. When mounting the bracket and radio to your car, make sure it is mechanically strong. Also provide a good electrical connection to the chassis of the vehicle. Proceed as follows to mount the transceiver. Mount the Transceiver After you have determined the most convenient location in your vehicle, hold the mobile radio with the mounting bracket in the exact location desired. If nothing will Interfere with mounting it in the desired position, remove the thumbscrews and use the mounting bracket as a template to mark the holes for the mounting screws. Before drilling the holes. make sure nothing behind the surface will be damaged or interfere with the installation.
Electrical Connections
The Stryker SR655 is designed to work on any 13.8 volt DC. negative ground electrical source. The condition of a vehicle’s electrical system can have a profound affect on the performance of the radio. A low battery, worn generatodaftemator. or poor voltage regulator will seriously impair the performance of the transceiver. Any of the above conditions could result in a high level of receiver noise generation or a Substantial loss of the transmitter’s RF output. Make sure that all these components on your vehicle’s electrical system are in good condition prior to installing the transceiver.

1. Before making any electrical connections make sure the volume (VOL) control is in theOFF position.
2. Connect the positive (+) red wire of the DC power cord to a positive 13.8-volt source at the vehicle fuse block. If connecting to the fuse block, it is recommended that a switched power source be used so that the power to the Transceiver is disconnected when the vehicle is off. This eliminates the possibility the transceiver draining the vehicle’s battery.
3. Connect the negative (-) black wire to a metal part of the vehicle’s frame. or chassis ground. Make sure that this is a good ground connection.

Antenna Connections
The Stryker SR-655 has a jack in the rear for a standard PL-259 antenna plug. If you are looking for the most range for your transmission. use a vertically polarized, quarter-wave length antenna. If antenna height is a problem, you may use a shorter, loaded-type whip antenna although you can expect some loss of transmission range. Your antenna should always be adjusted for the lowest possible SWR (1.5 or less.) To adjust your antenna for best performance. you can take advantage of your radio’s built in SWR meter. Failure to properly adjust your antenna(s) will diminish your operational range and could result in damage to your radio. Damage that results from operating with high SWRs is not covered under your factory warranty!
Tuning the Antenna for Optimum SWR
For maximum performance we recommend the Stryker SR-2K
Trucker antenna or the Stryker SR-5K Magnetic Mount.
Antenna length is directly related to signal frequency. Therefore, it must be tuned to resonate optimally throughout the frequency range of the transceiver.
Lower frequencies require a longer antenna than higher frequencies.
Due to the various methods of adjusting antennas for proper SWR, we have chosen what we think is the optimum method:
A. Antennas with adjustable screws (setscrews).
Start with the antenna extended and tighten the setscrew lightly

1. enough so that the antenna can be lightly tapped with your finger for easy adjustment. Set your Stryker radio to your desired operating frequency or the 2

2. center of the range of frequencies you plan to use. Press the PTT (Press-To-Talk) switch, and tap the antenna (making it shorter).
   The SWR meter will show a lower reading each time the antenna is tapped. By continuing to shorten the antenna, you will notice the SWR reading will reach a low point and then start rising again. This means that you have passed the optimum point for the  middle frequency. Extend the antenna a short distance and again follow the procedure

3. above. When the lowest point has been reached, switch to the lowest

4. frequency you plan to operate on and then to the highest and compare SWR readings. They should be almost equal.
   B. Antennas that must be cut to proper length. Follow the procedure as in A above, but adjust the length by cutting
   1. in 1⁄8″ increments until a good match is obtained. Be very careful not to cut too much off the antenna at one time.
   2. Once it is cut, it can no longer be lengthened.

5. The whip is easily cut by filing a notch all the way around, then breaking the piece off with pliers.

NOTE:
The proper setting is achieved when the SWR is 1.5 or below and when it has the same reading for the low and high frequencies in the range you plan to use.
External Speaker
The external speaker jack (EXT) on the rear panel is used for remote receiver monitoring. The external speaker should have 8 ohms impedance and be able to handle at least four watts. When the external speaker is plugged in, the internal speaker is disabled.
Programming Jack
Using this jack and the optional USB preprogramming cable you can change many of the default options that your radio has. Our programming software is available for download via our website.
Public Address
To use the transceiver as a public address system, connect an external 8 ohm speaker that is able to handle at least four watts to the PA jack on the rear panel. Direct the speaker away from the microphone to prevent acoustic feedback. Physical separation or isolation of the microphone and speaker is important when operating the PA at high output levels.
Improper Radio Adjustments
Service by unqualified technicians could result in damage to your radio. Never allow anyone to disable your radio’s modulation limiting circuitry. We have designed your radio for optimal performance and durability. Disabling this circuitry could damage your radio and potentially void your factory warranty!

OPERATING GUIDE

1. FUNC: Pressing this button in for approximately three seconds allows you to access the function menu.
2. Mon: The variable Mon control (talk back) is used to monitor your awn voice.This can be used to compare different microphones. To increase the volume of the talk back rotate the control clockwise. To decrease rotate counterclockwise. To turn off the talk back rotate the control completely counterclockwise.
3. Transmit Power or PWR – This variable control allows you to adjust your power output.
4. Band Selector: This switch allows you to switch bands, each band contains 40 channels, with each channel being on a different frequency.
5. Dimmer Switch: This switch controls the brightness for the front panel. To adjust the brightness move this switch to the left ‘DIM” setting and then rotate the channel selector clockwise for more light a counter-clockwise for less.
6. HIC: This is the Hi-Cit Filter, once this function is enabled, the radio will cut out high frequency interference. Use is dependent on reception conditions.
7. RB: This switch controls the ‘roger beep” circuitry. Simply put the roger beep is a tone that sounds when a radio operator un-keys their microphone. When the switch is on the RB position the roger beep is turned on. When moved the switch is moved to the middle position it is switched off.
8. PRG: This switch allows you to select which roger beep is will be activated when the RB switch is on. It also allows you select if you’d like the auto squelch activated and lets you add specific channels to scanned when the scan feature is activated. See section ‘PRG Menu’ for more details on this function.
9. +10Khz-: This switch will add 10 Khz to your current operating frequency.
10. RX / TX: The TX symbol will appear when the radio is receiving and the TX symbol will appear when the radio is transmitting.
11. Channel Display: The channel display indicates the currently selected channel.
12. VFO: The VFO switch allows you to move through the radios entire frequency range without changing bands. To use VFO mode move this switch all the way to the right position. For Band operation this switch should be in the middle position.
13. Scan I CH9 I CH19: Pressing this button once when the radio is in band mode will automatically take you to CH9 of which ever band you are currently on. Pressing it a second time will bring you to CH19 on your current band To scan channels in band mode you must first press and release the FUNC button and then press the Scan button. the radio will then start to scan. In VFO mode this button will only enable scanning, therefore it’s notnecessary to first press the FUNC button.
14. Color: Pressing this button changes the color of the front panel and I display. Each time it’s pressed it will change to a new color. Pressing this button allows you to select the color loop mode where the radio will automatically cycle through all of the colors.
15. Mode: This switch controls what mode of operation the radio is in, option are AM. FM & PA.
16. Microphone Input: The Stryker SR655 accepts microphones with a female 4 pin connector. For maximum performance use the SR-6SBC noise canceling microphone. Please see our website for further details.
17. On/Off Volume Control: Turn clockwise to apply power to the unit and to set the desired listening level. During normal operation, the VOLUME control is used to adjust the output level obtained either at the transceiver speaker or the external speaker, if used.
18. Squelch: This control is used to cut off or eliminate receiver background noise in the absence of an incoming signal. For maximum receiver sensitivity it is desired that the control be adjusted only to the point where the receiver background noise or ambient backgrounds noise is eliminated. Turn fully counterclockwise then slowly clockwise until the receiver noise disappears. Any signal to be received must now be slightly stronger than the average received noise.
19. Microphone Gain: Adjusts the microphone gain in the transmit and PA modes. This controls the gain to the extent that full talk power is available several inches away from the microphone.
20. RF Gain: This control is used to reduce the gain of the RF (receive) amplifier under strong signal conditions. For maximum receiver sensitivity this control should be turn all the way to the right (clockwise).
21. Noise Blanker / ANL Switch: When this switch is in the NB position the noise Blanker circuits are activate. The NB+ activates both the noise blank and the Automatic Noise Limiter. The Noise Blanker is very effective in eliminating repetitive pulse type noise usually associated with ignition systems. The ANL helps reduce other types of noise. We recommend using the NB + setting. )
22. Echo Volume: Varies the volume or number of echo repetitions. To increase the echo volume. rotate the control clockwise.
23. Echo Delay: The Echo switch turn the echo on. A big advantage to this is you can turn it off and then back on with the switch without the need to adjust your volume & delay potentiometer To turn the echo off simply move the switch to the middle position.
24. RX Tone: This feature allows you to change the receiver frequency response of the radio. you can choose from 2.0Khz, 2.5Kkhz, 3.0khz, 3.5khz and 4.0K hz. Select which option sounds to your ear.
25. COA: This control operates slightly differently than a typical clarifier. At the 12 o’clock position it will be at +OK. tuning one click to the right will add +5K and once more to the right will add +10K. The opposite would be true when turned to the left from the 12 o’clock position. The first click to the left would be -5K and the second click would be -10K. You will find that this is much more useful than a clarifier typically is on an AM/FM radio.
26. Channel Selector: This control is used to select the desired transmit and receive channel

ALTERNATE MICROPHONES AND INSTALLATION

For best results, the user should select a low-impedance dynamic type microphone or a transistorized microphone. Transistorized type microphones have low output impedance characteristics. The microphones must be provided with a four-lead cable. The audio
conductor and its shielded lead comprise two of the leads. The third lead is for transmit control and fourth is for receiving control. The microphone should provide the functions shown in the schematic below.
4 WIRE MIC CABLE

If the microphone to be used is provided with pre-cut leads, they must be revised as follows.
Cut leads so that they extend 7/16″ beyond the plastic insulating jacket

1. of the microphone cable.
   All leads should be cut to the same length. Strip the ends of each wire

2. 1/8″ and tin the exposed wire.

Before beginning the actual wiring, read carefully the circuit and wiring information provided with the microphone you select. Use the minimum heat required in soldering the connections. Keep the exposed wire lengths to a minimum to avoid shorting when the microphone plug is reassembled.

To wire the microphone cable to the plug provided, proceed as follows:

1. Remove the retaining screw.
2. Unscrew the housing from the pin receptacle body.
3. Loosen the two cable clamp retainer screws.
4. Feed the microphone cable through the housing, knurled ring and  washer as shown Figure 2.

This function basically emits an audible beep whena feature is turned on or off, for example moving the NB switch to NB+position. TOT: This menu is used to set transmitting limit time. When pressing PTT key at a single time longer than the due time setup in advance, the radio would stop transmitting automatically and the speaker will emit a voice prompt until the PTT key is released. Then. the radio can transmit again.
Options: 30-600s Step: 30s Default: 180s SCM: This menu is used to set the Scan mode. Options are as follows: SO: When SO is selected, scan would stop when a valid signal is detected. The radio would resume scanning after signal disappears for 5s. Ti: When TI is selected, scan would stop when a valid signal is detected. The radio would resume scanning 5 seconds later, whether signal disappears or not. Default: SO SCT: Scan resume time. When the scanned signal disappears, how many seconds before it will start to scan again.
Options: 5S 108 155. TSR: Choose whether to enable the Transmitting SWR Protection function or not. ON: When ON is selected, the radio will detect the SWR of your antenna. Once the SWR is beyond the SWR limit set in advance, the radio would stop transmitting automatically and the speaker will emit a voice prompt. Then, 1-11 S” icon will display on the LCD to remind you that the antenna SWR is too high.
OFF: When OFF is selected, the SWR Protection function is disabled.
( NOTE: To protect the radio from long transmission under high SWR, the radio would automatically start SWR Protection once the SWR Value is higher than 20:1.
TDC: Choose whether to enable Voltage Protection function or not.
ON: When ON is selected, the radio will detect the supplied voltage. Once the voltage surpasses the limit that was set in advance, the radio would display ‘DC LO’ or ‘DC HI’ to remind you that the voltage is not in normal state. Meanwhile, the radio will prohibit transmitting and emit a beep sound.
OFF: When OFF is selected, the Power Supplying Voltage is disabled.
Default: ON LCD: This option lets you choose if you’d like to display the following on the LCD meter. The first option is to display the model name of the radio. the second option will display the DC voltage present at the power
jack and the third option will display the model name during receive and the voltage during transmit
