GENERAL INFORMATION
Your transceiver has been factory aligned and tested to

trimmers, coils and resistors in the transceiver were
preset at the factory. They should only be readjusted by
a qualified technician who is familiar with this transceiver

service or alignment without factory authorization can
void the transceiver warranty.
When operated properly, the transceiver will provide
years of service and enjoyment without requiring further
realignment. The information in this section gives some
general service procedures requiring little or no test
equipment.
