6-1. 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 trim-
mers 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 in-
formation in this section gives some general service
procedures which can be accomplished without
sophisticated test equipment.
