ELECTRICAL ADJUSTMENT
FREQUENCY ADJUSTMENT
Connection:
Note: Make this adjustment, if either ANTENNA board or CONTROL
board in this set was replaced or if equivalent work was executed,
because these boards have been adjusted in a pair.
2. Disconnect a loop antenna assy from the ANTENNA board,
and connect a dummy antenna coil (2.2µH (1-410-320-00))
between TP (ANT+) andTP (ANT–) of theANTENNA board.
3. Connect the ANTENNA MODULE, ANTENNA CONTROL-
LER, RADIO for adjustment (e.g. multi-band radio having ex-
ternal antenna input terminal (ICF-SW7600G)), and level meter
as shown below.
Adjustment Procedure:
1. Adjust the receiving frequency of the radio for adjustment (ICF-
SW7600G) to the AM RF SSG frequency (refer to the follow-
ing table).
2. Adjust respective adjusting elements on the CONTROL board
so that the level meter reading becomes maximum when the
frequency of AM RF SSG and the FREQ SELECT switch are
set as listed below.
