6. MAINTENANCE AND ADJUSTMENTS
6-1. 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 and coils in your transceiver
were preset at the factory and should only be
readjusted by a qualified technician with proper
test equipment. Attempting service or alignment
without factory authorization can void the
transceiver's warranty.
When operated properly, the transceiver can give
years of service without requiring realignment. The
information in this section gives some general
service procedures which can be accomplished
without sophisticated test equipment.
6-2. SERVICE
Should it ever become necessary to return the
equipment to your servicing dealer or KENWOOD
authorized service center for repair, pack it in its
original box and packing, and include a full
description of the problems involved. Also include
your telephone number. You need not return
accessory items unless directly related to the
service problem.
You may return your radio for service to the
Authorized KENWOOD Dealer from whom you
purchased it. A copy of the service report will be
returned with the unit. Please do not send sub-
assemblies or printed circuit boards. Send the
complete unit, in its original boxes and packing.
Tag all returned items with your name and call for
identification. Please mention the model and serial
number of your radio in any correspondence,
whether phone or written. For future reference,
record this information in the space provided on
the back cover of this manual.
