Adjustment Condition & Tuning
Connect the transceiver by cloning cable
(OPC-478) to a PC (IBM compatible) and
boot up the cloning software.
Be sure to use a tester with more than 50
ohm/V internal resistance when making
each test.
Set the transceiver to the highest
band frequency on the TX condition, and set
the LV voltage as follows by means of
spreadable coil L16.
Adj. Freq.

TX Side
Set the transceiver to the lowest
band frequency, and check that each of
the LV voltage is within as follows.

Connect a power meter or attenuator to the
antenna terminal. Loose coupling the ANT
and frequency counter.
Set the transceiver to near the TX greatest
high band frequency and set the unit to TX.
Use adjustment software to adjust the TX
frequency to the values below.
