ADJUSTMENT
Idling Current
Required measurement equipment: DC Voltmeter
1. Setup
(1) Place the unit at an ordinary position avoiding direct air
flow from an air-conditioner or fan. Do the adjustment at
a temperature between 15 °C (59 °F) and 30 °C (86 °F).
(2) Set control as follows.
* POWER switch — OFF ( HH).
«VOLUME control — fully counterclockwise ( O
min.)
* SPEAKER terminals — open: do not connect the
speakers, dummy load etc.
2. Adjustment
(1
~~
Remove top cover. And then connect DC Voltmeter to the
test points CN31 and CN32 of CUP11904 Main P.W.B.
Connect power cord to AC wall outlet, and turn POWER
switch "ON" ( m=).
Right after power on, adjust VR31 and VR32 so that the
DC voltmeter reads 10 +1mV.
Then after 2 minutes warm up adjust VR31 and VR32 so
that the DC voltmeter reads 10 +1mV.
And after 10 minutes warm up adjust VR31 and VR32 so
that the DC voltmeter reads 10 +0.5mvV.
