Table 5-1. Troubleshooting for the CDM Control Station
Possible Solution(s)
Check the cabling to the radio and the
control station.
Ensure proper radio programming.
Verify Fuse is OK.
The control station by default expects
a desk mic. If another audio accessory
is to be used, reprogram switch set-
tings accordingly.
The desk mic must have a jumper in-
stalled to allow proper operation.
Ensure that Accessory Configuration/
RX Audio on the radio is set for Fil-
tered Audio.
Ensure radios are programmed with
the correct TPL/DPL code.
Verify correct I/O programming of the
accessory connector of the control sta-
tion radio.
Verify correct programming of field
radios.
Verify control station cabling.
Check for proper wiring of deskset
and control station.
