C.ritical Components Information

Components having special characteristics are marked [K
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
by015uF

0 Leakage current must not exceed 0.5mA.
0 Be sure to test for leakage with the AC plug in both polarities.

CAUTION

WARNING: CHEMICAL CONTENT NOTICE!

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and
possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-

SON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose

eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands before

handling food.

About lead-free solder / fifil \ > 51 I: 3

The Ioil side of all P.C.B.:s used for this product are
soldered with lead-free soldering material which is an alloy
of Sn+Ag+Cu (tin + silver + copper).

However, the surface mount devices on the component
side of the DSP P.C.B., FUNCTION P.C.B. and
CONVERSION P.C.B. are soldered with the lead solder.

Among some types of lead-free solder currently available,
it is recommended to use one of the following types for the
repair work.

- Sn + Ag + Cu (tin + silver + copper)

- Sn + Cu (tin + copper)

- Sn + Zn + Bi (tin + zinc + bismuth)

Caution:

1. As the melting point temperature of the lead-free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.

2. If lead solder must be used, be sure to remove lead-
free solder from each terminal section of the parts to be
replaced and from the area around it completely before
soldering, or make sure that the lead-free solder and
lead solder melt together fully.
