TROUBLESHOOTING
NOTE: When replacing the internal mechanism (computer part) of the audio system, be careful that no part of your body or clothing comes in contact with the terminals of the leads from the IC. etc. of the replacement part (spare part).

Always inspect the trouble taking the following items into consideration.
^ Open or short circuit of the wire harness
^ Connector or terminal connection fault.
The term "AM" includes LW, MW and the term "FM" includes UKW.
