Section IV Operation
CONTROLS AND INDICATORS
There are eighteen controls, 2 meters, 1 LCD and 1 jack on the front panel of your
2010 GTL WX.
A. CONTROL FUNCTIONS
1. POWER SWITCH. Press in to turn on radio. Press in, again, and release to turn off
radio.
2. DYNAMIKE. Adjusts the microphone gain in the transmit mode. This controls the
gain to the extent that full talk power is available several inches away from the
microphone.
3. VOLUME. Turn clockwise to set the desired listening level.
4. SQUELCH . This control is used to cut off or eliminate receiver background noise
in the absence of an incoming signal. For maximum receiver sensitivity the control
should be adjusted only to the point where the receiver background noise or
ambient background 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. Further clockwise rotation
will increase the threshold level which a signal must overcome in order to be
heard. Only strong signals will be heard at a maximum clockwise setting.
5. RF GAIN CONTROL. Adjust as required to optimize the signal. This control is
used primarily to optimize reception in strong signal areas. Gain is reduced by
counterclockwise rotation of the control.
