1O. ADJUSTMENTS
ldle CurrentAdjustment 1. Without any load or input signal, turn the VOLUME control to the minimum position. 2. T\rrn the POWER switch ON and let stand for 10 minutes. 3. Check that the voltage (DC) between TP-L (TP-R) terminal (-) on the complex assembly and SPEAKERS + terminal (+) on the rear panel lies within 2.35mV-L17.5mV range. 4. If the voltage is lessthan 2.35mV, cut jumper JP 1(JP 2). It the voltage exceeds117.bmV, check for circuit failure.
FM Tuner Adiustment o Connect the FM signal generator (FM SG) to the FM ANTENNA 300O terminal through a 300O dummy antenna. o Set the FM (FUNCTION) switch to the ON position and the MONO/MUTE OFF switch to the MONO/MUTE OFF position. . Connect between pin 10 and pin 38 of Q5 on the control assembly (GWX-721) for a short period of time. (The test frequencies are stored in memories. This operation is program controlled of the computer.) (*1) Tune the FM SG to the SX-4. (*2) Connect the FM multiplex signal generator to the FM SG external modulator terminal. Set the modulation to a Main ]-kHzlL+P"l!67.5k}l2 deviation. Pilot 19kHzl!7.]oklHz deviation.
