    ELECTRICAL ADJUSTMENT Method of Using the Jig Remote Controller Most of the video circuit and the deflection circuit of this set can be adjusted by using the jig remote controller. Jig remote controller: RC-AVC01 The jig remote controller RC-AVC01 has the two operating modes. One is the NORMAL mode and the other is the TEST mode. Either the NORMAL mode or the TEST mode can be selected by short-circuiting or opening the shorting land of the printed foil pattern.
