i GENERAL INFORMATION
M HOW THE TX FINAL MODULE IS PROTECTED
@ BATTERY PRECAUTION
Your TM-201B has been factory aligned and tested to specification before
shipment. Under normal circumstances, the transceiver will operate in accor-
dance with these operating instructions.
If your transceiver fails to work, contact the authorized dealer from which you
purchased it for quick, reliable repair. All adjustable trimmers 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, may void the
warranty, peoceed with caution!
Final module protection is provided by sampling the reflected power. As the
reflected power is increased (higher SWR) transmitter drive is reduced, thus
decreasing input to the final module. This in turn reduces collector loss, protec-
ting the final transistor.
@ ORDERING SPARE PARTS
When charging your vehicle battery, or when jumpstarting a dead battery,
ALWAYS disconnect the power cable from the back of the transceiver, or
serious damage may result
