SECTION 3 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. [ANTENNA BOARD] (Conductor Side)
Adjustment and Connection Location:
1. Connect AM RF SSG to the TP (DUMMY-IN) and TP (SG GND) of the ANTENNA board.

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+) and TP (ANT) of the ANTENNA board. 3. Connect the ANTENNA MODULE, ANTENNA CONTROLLER, RADIO for adjustment (e.g. multi-band radio having external antenna input terminal (ICF-SW7600G)), and level meter as shown below.
