correctly set to enable effective operation with your transceiver.
The ARD9000 allows you to apply separate settings for analog and digital
transmissions (also see the diagram below).
.
1. Connect the supplied speaker microphone to the ARD9000 first, then
connect your radio to the RADIO terminal of the ARD9000 by using your
prepared connection cable. Now turn ON the ARD9000.
2. Make sure that the output level pot ANA-OUTO or DIG-OUTO is set to
factory default.
3. Press PTT switch on the supplied speaker microphone and speak
normally into the speaker-microphone.
In case the OVERLOAD LED cc is not lit, it means that the microphonec s
sMIC-INI level has not been set properly. Refer to the previous
IMicrophone levelI chapter to correct this level first.
4. Adjust microphone gain control on the radio transceiver to suitable level.
It is recommended that you adjust the level so that the ALC function is
activated. If the ALC function activates too much, it might create audio
distortion and as a result, the communication link with the distant station
may be broken.
5. Adjust the output level pot on the bottom side of the ARD9000 when the
microphone gain control on the radio transceiver does not adjust for
sufficient level.
