6. MAINTENANCE
6-1. 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
these instruction manuals. 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 information in this section
gives some general service procedures which can be
accomplished without sophisticated test equipment.
