I TO SERVICE PERSONNEL

1. Critical Components Information.

Components having special characteristics are marked A
and must be replaced with parts having specifications equal
to those originally installed.

2. Leakage Current Measurement (For 120V Models Only).
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.

0 Meter impedance should be equivalent to 1500 ohm shunted
by 0.15I1F.

o Leakage current must not exceed 0.5mA.

0 Be sure to test for leakage with the AC plug in both
polarities.

CAUTION: USE OF CONTROLS OR ADJUSTMENTS
OR PERFORMANCE OF PROCEDURES
OTHER THAN THOSE SPECIFIED
HEREIN MAY RESULT IN HAZARDOUS
RADIATION EXPOSURE.

THE MINI DISC RECORDER SHOULD NOT BE
ADJUSTED OR REPAIRED BY ANYONE EXCEPT
