3.2.1.5 Com Radio
The Com Radio Setup function is used to modify the RF Squelch and Mic Gain levels. Typical values
from the factory are RF Squelch = 56 and Mic Gain = 255, which are satisfactory for most installations.
The RF Squelch value is used by the Com function to control its squelch level. The larger the value that is
set the stronger the signal must be in order for the radio to break squelch.
To edit the RF Squelch value,
press the
EDIT RF SQUELCH
line select key. Turn the small, inner knob to adjust the squelch value (the
RF Squelch value is restricted to a number from 25 to 100). When the desired value is selected, press the
MENU/ENTER
key or the
SAVE RF SQUELCH
line select key to save the setting.
The microphone gain is used by the Com function to control the microphone pre-amplifier gain. The larger
the value that is set the higher the pre-amplifier gain is. To edit the Mic Gain value press the
EDIT MIC
GAIN
line select key. Turn the small, inner knob to adjust the gain value (the Mic Gain value is restricted
to a number from 0 to 255). When the desired value is selected, press the
MENU/ENTER
key or the
SAVE MIC GAIN
line select key to save the setting.
