The following chart is designed to help you correct
problems which are not equipment malfunctions.

If you are unable to locate the cause of a problem or
solve it through the use of this chart, contact your
nearest Icom Dealer or Service Center.

PROBLEM

POWER SUPPLY

RECEIVE

POSSIBLE CAUSE

SOLUTION

REF.

Power does not come 
on when the [POWER] 
switch is pushed. 

No sound comes from 
the speaker.

Sensitivity is low.

Receive audio is distor-
ted.

Receive signal is distor-
ted with strong signals.

DC power cable is improperly 
connected.

Fuse is blown.

Battery is exhausted if you are using 
a 12 V battery as the power source.

Reconnect the power cable correctly.

Check for the cause, then replace the 
fuse with a spare one.

(Fuses are installed in two places. One is 
installed in the DC power cable and the 
other is installed in the PA unit.

Check the battery voltage with the 
[POWER] pushed IN.

Volume level is set too low.

The squelch is closed.

The transceiver is in the transmitting 
condition.

An external speaker or headphones 
are connected.

The antenna is not connected properly.

The antenna feed line is cut or shorted.

unit, if connected.

Check the external speaker or head-
phone plug connection.

Check the speaker ON/OFF switch or 
speaker A/B switch, when an optional 
SP-20 

EXTERNAL SPEAKER

 is in use.

Reconnect to the antenna connector.

Check the feed line and correct any 
improper conditions.

Select an antenna suitable for the 
operating frequency.
Make sure that [ANT1] is used for 
frequencies less than 60 MHz and 
[ANT2] is used for frequencies of 60 
MHz and above.

Push [TUNE] to manually tune the 
antenna.

Push [ATT] to turn the function OFF.

Select a suitable operating mode.

Set [SHIFT] to the center position.
