SAFETY CHECK-OUT
After correcting the original service problem, perform the follow»

ing safety checks before releasing the set to the customer:

Check the antenna terminals. metal trim. metallized knobs, screws,

and all other exposed metal parts for AC leakage.

Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and

from all exposed metal pans to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microampers.) Leak-

KLASS I LASERAPPARAT

This Compact Disc player is classified as a
CLASS 1 LASER product.

The CLASS 1 LASER PRODUCT label is
located on the rear exterior.

CAUTION

Use of controls or adjustments or performance of pro-
cedures other than those specified herein may result in
hazardous radiation exposure.

SAFETY-RELATED COMPONENT WARNING

COMPONENTS IDENTIFIED BY MARK A OR DOTTED
LINE WITH MARK A ON THE SCHEMATIC DIAGRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB~
LISHED BY SONY.

age current can be measured by any one of three methods.
1.

A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers' instructions to use these
instniments.

A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.

Measuring the voltage drop across a resistor by means of a VOM
or battery-operated AC voltmeter. The limit" indication is 0.75
V. so analog meters must have an accurate lowvvoltage scale.
The Simpson 250 and Sanwa SH-63Trd are examples of a pas-
sive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are suitable. (See Fig. A)
