CONTINUATION
12. Front Panel Meter: Indicates receive signal strength and RF output power. The
top bar on the meter indicates RF output power. The bottom bar indicates
receive signal strength.
13. Microphone Connector: This Stryker Radio accepts microphones with a
female 4 pin connector. For further wiring information please see the next page
of this manual.
14. 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.
15. 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.
16. 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)
17. 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.
18. Echo Delay: Varies the amount of delay, or duration of the echo repetition.
Rotate clockwise to increase the amount of delay and counterclockwise
to decrease.
19. Echo Volume: Varies the volume or number of echo repetitions. To increase
the echo volume, rotate the control clockwise.
