IDLING CURRENT
(1) Set controls as fotlows.
POWER Switch ~ off (mr)
VOLUME Control = 0 (min.)
SPEAKERS — off (gn)
Temperature =» 15°C ~ 30°C (59°F ~ 86°F)
VR305 and VR306 of the 1U-2718-1 (Main Unit) — MIN. (CY)
(2) Connect OC Voltmeter to the T.P Loh and T.P Reh of the 1U-2718.
(3) Tum ‘the Power Switch on’and rotate VR305 clockwise so that the DC Voltmeter reads 2.5 mV 40.2 mV DC at the TP Leh.
Follow the same procedure to VR306 for T.P Rech.
(4) Warm up for three minutes, then readjust VR305 and VR306 so that the DC Voltmeter reads 2.5 mV 10.5 mV DC.
(5) Warm up for 10 minutes, then readjust VR 305 and VR306 so that the DC Voltmeter reads 2.5 mV +0.5 mV DC.
Adjust T503 for maximum height and best symmetry curve.
