MAINTENANCE
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 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

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.
