Adjusting the audio output level– AF OUT
Via the “AF OUT” menu, you can adjust the audio output level of the receiver. The level can be adjusted in eight steps. Adapt the level of the audio output (AF OUT) to the input of the connected unit. The following figures are a guide to the best settings:
y Line levelinput: | 0 to +18 dB |
y Microphone level input: | −24 to −6 dB |
Adjusting the squelch threshold– SQELCH
Thereceiver is equippedwitha squelchthat canbe adjusted via the “SQELCH” menu. The squelch eliminates annoying noise when the transmitter is switched off. It also suppresses sudden noise when there is no longer sufficient transmitter power received by the receiver.
Note:
Before adjusting the squelch threshold to a different setting, set the volume on a connected amplifier to the minimum.
There are three possible squelch settings:
y LO | = | low |
y MID | = | middle |
y HI | = | high |
Selecting the setting “LO” reduces the squelch threshold, selecting the setting “HI” increases the squelch threshold. Adjust the squelch threshold – with the transmitter switched off – to the lowest possible setting that suppresses hissing noise.
Important notes:
If the squelch threshold is adjusted too high, the transmission range will be reduced. Therefore, always adjust the squelch threshold to the lowest possible setting.
When in the setting mode of the “SQELCH” menu, pressing the button (DOWN) for more than three seconds will switchthe squelchoff. “SQ.OFF” appears on the display. If no RF signal is being received, hissing noise will occur. This setting is for test purposes only.
