SECTION 3 ELECTRICAL ADJUSTMENT FREQUENCY ADJUSTMENT
Adjustment and Connection Location:
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)
1. Connect AM RF SSG to the TP (DUMMY-IN) and TP (SG GND) of the ANTENNA board. J2

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.

Adjustment Procedure: 1. Adjust the receiving frequency of the radio for adjustment (ICFSW7600G) to the AM RF SSG frequency (refer to the following 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.
