Teac CD-5 - Laser Diode and Voltage Checks

CD-5
3. Laser diode check
(lop (Intensity Optimum) check]
Connect a DC voltmeter to both ends of R415 on SERVO
PCB. Measure the DC voltage while playing a disc to check
that the measured value does not exceed the Iop value
indicated on the pickup by 5mA. (1=measured value/22)
If the measured value is higher than that indicated, the
pickup may be damaged.
* Pay special attention that parts are not damaged by
Static electricity.

VOLTAGE CONVERSION
(For general export/U.S.A./Canada models)
Be sure to remove the power cord from the AC outlet
before repositioning the voltage converter switch.
1. Locate the voltage selector on the rear panel.
2. Using a flat- bladed screwdriver, set to the appropriate
230 V or 120 V position according to your area.
