Initial Setting

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 one included, you will
need to rewire your microphone cable to match the pins of the ARD9000MK2
and then adjust the microphone level as described in the following steps:
1. Connect your microphone to the Microphone connector on the
ARD9000MK2.
2. Make sure that the input level pot "MIC-IN" located on the bottom
side of the unit is set to factory default (9 o'clock position).
3. Press the 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-IN" pot on the bottom side of the ARD9000MK2 by
observing the OVERLOAD LED as follows:

Output Level to Radio

Before readjusting the output levels to the transceiver, be sure that the
microphone level is correctly set first, as described above.
Although the factory setting should work with most transceivers, it is possible to
readjust the audio output level manually, as described below. This level must be
correctly set to enable effective operation with your transceiver.
The ARD9000MK2 allows you to apply separate settings for analog and digital
transmissions.
.
1. Connect the supplied speaker-microphone to the ARD9000MK2 first,
then connect your radio to the RADIO connector of the ARD9000MK2
by using your prepared connection cable. Now turn on the
ARD9000MK2.
2. Make sure that the output level pot "ANA-OUT" or "DIG-OUT" located
on the bottom side of the unit is set to factory default (4 o'clock
position for analog, 9 o'clock position for digital).
