Kenwood TS-850S - Manual (Page 72)

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

equipment to your servicing dealer or KENWOOD
authorized service center for repair, pack in its

accessory items unless directly related to the
service problem.
You may return your radio for service to the
Authorized KENWOOD Dealer from whom you

assemblies or printed circuit boards. Send the
