Presetting
Output Level to Radio Transceiver
This level has to be supplied properly to the radio transceiver for operation.
1. Connect the supplied hand microphone to the ARD9800 first. Then connect
your radio to the RADIO terminal on the ARD9800 by using your prepared
connection cable certainly. Turn ON the ARD9800.
2. Make sure that the output level adjusting volume (y) is set to minimum.
3. Select the mode switch (i) to [10101] position as digital.
4. Press PTT switch on the supplied hand microphone.
5. Adjust microphone gain control on the radio transceiver to suitable level.
Particularly, it is recommended to adjust the level that activates ALC function.
If the ALC function activates too much, it might create audio distortion. As a
result, the communication with a distant station might be compromised.
6. Adjust the output level located on the bottom side of the ARD9800 when the
microphone gain control on the radio transceiver does not adjust for sufficient
level.
7. If the microphone gain is still not enough even though you proceeded as per
step (6.), turn OFF the ARD9800 first and go to step (8).
8. Remove the upper cover of the ARD9800 and locate the jumper pin for Output
level setting. Change the jumper pin (The default is inserted between 1-2) to 2-
3 for high level. Put the cover back into place.
Proceed again with steps 1 to 6.
9. If the microphone gain is still not enough, set the ATT command to OFF with a
terminal software . Then try again steps 1 to 6.
