The power switch of this unit is located on the secondary side of power transformer. So, be sure to disconnect
the power cord from the socket before starting the repair work. Also, when repairing the digital circuit, discon-
nect the power cord and then short-circuit across the gold capacitors (C920, C921, 2.3 V 3.3F) with a resistor
(10 ohms, about 1 W) to discharge the voltage.
