5. MAINTENANCE
GENERAL INFORMATION
Your transceiver has been factory aligned and tested to
specification
before shipment. Under normal cir­
cumstances the transceiver will operate in accordance with
these operating instructions. All adjustable trimmers and
coils in your transceiver has been adjusted 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 will provide many
years of service without requiring realignment. The infor­
mation in this section gives some general service pro­
cedures which can be accomplished without sophisticated
test 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
