Preparation(1) Avoid direct blow from an air conditioner or an electric fan, and adjust the unit at normal room temperature15 °C ~ 30 °C (59 °F ~ 86 °F).(2) Presetting• POWER (Power source switch) OFF• SPEAKER (Speaker terminal) No load(Do not connect speaker, dummy resistor, etc.)2. Adjustment(1) Remove top cover and set VR101 FL, FR, C, SL, SR, on Main Amp. Unit, VR401, VR402 on 2ch- Amp.Unit at fully counterclockwise (c) position.(2) Connect DC Voltmeter to test points (FRONT-Lch: TP101, FRONT-Rch: TP105, CENTER ch: TP103, SURROUND-Lch: TP102, SURROUND-Rch: TP104, SURROUND-BACK Lch: TP401, SURROUND-BACK Rch: TP402).(3) Connect power cord to AC Line, and turn power switch "ON".(4) Presetting.MASTER VOLUME : "---" counterclockwise (c min.)SPEAKER (Speaker terminal) : No load(Do not connect speaker, dummy resistor, etc.)MODE : 7CH STEREO (5CH STEREO)FUNCTION : CD(5) Within 2 minutes after the power on, turn VR101 clockwise (x) to adjust the TEST POINT voltage to 1.5 mV ± 0.5 mVDC.(6) After 10 minutes from the preset above, turn VR101 to set the voltage to 2.0 mV ± 0.5 mV DC.(7) Adjust the Variable Resistors of other channels in the same way.VR101SRTP104VR101FLTP101TP102VR101SLTP402VR402TP103VR101C VR101FRTP105F Lch S LchS Back RchTP401VR401S Back LchC ch S Rch F RchDC VoltmeterPCB MAIN ASSYPCB 2CH ASSY
