Preparation(1) Avoid direct blow from an air conditioner or an electricfan, and adjust the unit at normal room temperature 15 °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, onMain Amp. Unit, VR401, VR402 on 2ch- Amp. Unit at fullycounterclockwise ( ) position.(2) Connect DC Voltmeter to test points (FRONT-Lch:TP101, FRONT-Rch: TP105, CENTER ch: TP103, SUR-ROUND-Lch: TP102, SURROUND-Rch: TP104, SUR-ROUND-BACK Lch: TP402, SURROUND-BACK Rch:TP401).(3) Connect power cord to AC Line, and turn power switch"ON".(4) Presetting.MASTER VOLUME : "---" counterclockwise ( min.)SPEAKER (Speaker terminal) : No load(Do not connect speaker, dummy resistor, etc.)MODE : 7CH STEREOFUNCTION : CD(5) Within 2 minutes after the power on, turn VR101 clock-wise ( ) to adjust the TEST POINT voltage to1.5 mV ± 0.5 mV DC.(6) After 10 minutes from the preset above, turn VR101 toset the voltage to2.0 mV ± 0.5 mV DC.(7) Adjust the Variable Resistors of other channels in thesame way.VR104TP104VR101TP101VR102,TP102TP107VR107VR103,TP103VR105TP105F LchS LchS Back RchTP106VR106S Back LchC chS RchF RchDC Voltmeter
