VOLTAGE SELECTION
The voltage selector is located on the AC voltage selector box. If
adjustment is necessary, use a screwdriver in order to slide the selector
to match to the correct voltage.
Aim the remote control at the remote control sensor within
50”,
with no obstacles, and operate as shawn.
Notes concerning use:
0
Replace the battenes if control distance decreases or
operation becomes erratic.
0
Periodically clean the transmitter window on the remote
control and the sensor on the main unit with a soft cloth.
0
Exposing the sensor on the main unit to strong light can
interfere with operation. Change the lighting or the direction of the unit.
0
Keep the remote control away from moisture, excessive
heat, shock, and vibrations.
0
The remote control’s usable range is between 0.2 m
and 6 m (20’) away from the sensor.

DISASSEMBLY
Caution on Disassembly
Follow the below-mentioned notes when disassembling the
unit and reassembling it, to keep it safe and ensure excellent
performance:
1. Take cassette tape and compact disc out of the unit.
2. Be sure to remove the power supply plug from the wall
outlet before starting to disassemble the unit.
3. Take off nylon bands or wire holders where they need be
removed when disassembling the unit. After servicing the
unit, be sure to rearrange the leads where they were
before disassembling.
Note 1: if the power supply cannot be turned on, f& turn the gear
by hand as shown in Figure 7-3 to open the disc tray.
Note 2: Withdraw upward straight the flat cable.

. Resistor:
To differentiate the
are used: the symbol K means 1000 ohm and the symbol
means 1000 kohm and the resistor without any symbol is an
ohm resistor. The resistor designated “Fusible” is a fuse type
resistor.
l
Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means pica-farad and the unit of the capacitor
without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.
