General Information

Your transceiver has been factory aligned and tested to specification before shipment. Under normal circumstances, the transceiver
will operate in accordance with these operating instructions. All adjustable trimmers, coils, and resistors in the transceiver are preset at
the factory. They should only be readjusted by a qualified technician who is familiar with this transceiver and has the necessary test
equipment. Attempting service or alignment without factory authorization may void the transceiver warranty.
When operated properly, the transceiver will provide years of service and enjoyment without requiring further realignment. The
information in this section gives some general service procedures requiring little or no test equipment.

Service

If it is ever necessary to return the equipment to your dealer or service center for repairs, pack the transceiver in its original box and
packing material. Include a full description of the problems experienced. Include both your telephone number and fax number (if
available) along with your name and address in case the service technician needs to call for further information while investigating your
problem. Don't return accessory items unless you feel they are directly related to the service problem. Please do not send subassemblies
or printed circuit boards. Send the complete transceiver.
You may return your transceiver for service to the authorized KENWOOD dealer from whom you purchased it or any authorized
KENWOOD service center. A copy of the service report will be returned with the transceiver.
Tag all returned items with your name and call sign for identification. Please mention the model and serial number of the transceiver in
any communication regarding the problem.
