Rotate Semi-fixed resistors VR102 and VR202 fully counterclockwise as viewed from the solder side. 2. No signal is entered, as input signal. 3. Apply the source voltage 14.4 V between +12 V, REMOTE and GND terminals. 4. Adjust the VR102 (L-CH) and VR202 (R-CH) so that the digital voltmeter reading becomes the adjustment limits below. Adjustment Limits: 5 ± 0.2 mV Adjustment Location: digital voltmeter + ­ L-CH [R-CH AMP BOARD] R-CH R215 + VR202 R-CH [L-CH AMP BOARD] L-CH R115 + VR102 ­ 11 ­ SECTION 5 EXPLODED VIEWS NOTE: · -XX and -X mean standardized parts, so they may have some difference from the original one. · Color Indication of Appearance Parts Example: KNOB, BALANCE (WHITE) . . .
