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 level input: 0 to +18 dB
y Microphone level input: −24 to −6 dB
Adjusting the squelch threshold –
SQELCH
The receiver is equipped with a squelch that can be 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 MI D = m iddle
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 switch the squelch off. “SQ.OFF” appears on
the display. If no RF signal is being received, hissing
noise will occur. This setting is for test purposes only.
