Check whether:
The 30A fuse installed in the fuse holder located on the red wire
of the power cable is good.
The 6.3A fuse installed on the right side of the MICOM-2ET-
RDP connections box, next to the AC connection, is good.
Proper grounding cables are connected from the radio and from
the antenna tuner to the vehicle chassis.
While speaking, check RF power bars for activity.
The resulting RF power output is displayed in approximately
15W increments (bars) being added from the bottom of the

Three or more bars disappear from the RF power bar display.
There may be a problem in the antenna system. If the antenna
cabling or the antenna mast rigging position has changed since
the antenna was last tuned, the antenna tuner will not be
adjusted automatically. To retune the antenna tuner, press the
ENTER key. If transmission is still poor, inspect the tuner,
antenna and ground plane for loose connections or misplaced
parts. If no loose connections are found, call your service
representative for assistance.
There are no bars on the RF power bar display.

faulty microphone, faulty transmitter, overheating, or defective
antenna system.
