Kenwood TM-3530A - Manual (Page 33)

5. MAINTENANCE AND ADJUSTMENT
5-1. GENERAL INFORMATION
Your transceiver has been factory aligned and tested to
specification before shipment. Under normal circum­
stances, the transceiver will operate in accordance with
the instructions in this manual.
If your transceiver fails to work, contact the authorized
dealer from which you purchased it for quick, reliable re­
pair. 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 authori­
zation, may void the warranty.
When operated properly, the transceiver can give years
of service without requiring realignment. The informa­
tion in this section gives some general service proce­
dures which can be accomplished without sophisticated
test equipment.
5-2. SERVICE
Should it ever become necessary to return the equipment
to your dealer or 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 dir­
ectly related to the service problem. If you do include ac­
cessory items please list them in your correspondence.
You may return your radio for service to the Authorized
TRIO-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 identi­
fication.
Please mention the model and serial number of your ra­
dio in any correspondence, whether phone or written.
For future reference, record this information in the space
provided on the back cover of this manual.
