Presetting

Microphone Level

The microphone level has been properly adjusted at the factory with the
provided speaker-microphone. Therefore, no further adjustment is needed for
normal operation.
If you wish to use your own microphone rather than the included one, you will
need to wire your microphone connector to match the pins of the ARD9000, and
then adjust the microphone level as described in the following steps:
1. Connect your microphone to the Microphone connector on the
ARD9000.
2. Make sure that the input level pot MIC-INI is set to factory default.
3. Press PTT switch on your microphone and speak normally into the
microphone.
4. The OVERLOAD LED is lit either red for analog, or orange for digital
transmission (depending on your rotary switch position).
Adjust the MIC-INI pot, on the bottom side of the ARD9000, by
observing the OVERLOAD LED as follows:
LED off
LED sometimes lit
LED always on

Output Level to Radio

Before modifying the output levels to the transceiver, be sure that the
microphone level is correctly set first, as described in the previous chapter.
Although the factory setting should work with most transceivers, it is possible to
adjust the audio output level manually, as described below. This level must be
Input level too low
Input level optimal
Input level too high
