SAFETY PRECAUTIONS

WARNING

Before servicing this unit, familiarize yourself with the following precautions:

1. Many electrical and mechanical parts in this
chassis have special safety characteristics that
often pass unnoticed and the protection
afforded by them cannot necessarily be
obtained by using replacement components
rated for higher voltage, wattage, etc.
Replacement parts that have these special
safety characteristics are identified in this
manual and its supplements: electrical
components having such features are
identified by in the schematic diagram and
the parts list.

Before replacing any of these components,
read the parts list in this manual carefully. The
use of substitute replacement parts that do
not have the same safety characteristics as
specified in the parts list may create shock,
fire, or other hazards.

2. Before returning the set to the customer,
always do an AC leakage current check on the

exposed metal parts of the cabinet, such as
terminals, screw heads, and metal overlays, to
be sure the set is safe to operate danger of
electrical shock. Plug the AC line cord directly
into a 120 V AC outlet(USA Version) or 230 V
AC outlet(EU Version). (Do not use a line
isolation transformer during this check.) Be
sure your AC voltmeter has a sensitivity of
5000 Ω per volt or greater. Then connect a
1500 Ω 10 watt resistor, paralleled by a 0.15 µF
150 V AC capacitor, between a known good
earth ground(such as a water pipe, or conduit)
and the exposed metallic parts, one at a time.
Measure the AC voltage across the combination
of a 1500 Ω resistor and a 0.15 µF capacitor.
Reverse the AC plug at the AC outlet and
repeat AC voltage measurements for each
exposed metalic part. Voltage measured must
not exceed 0.75 V RMS. This corresponds to

0.2 mA AC. Any value exceeding this limit
constitutes a potential shock hazard and must
be corrected immediately.

Measuring methods are based on IHF and IEC standard 268-3
Measurements conditions,unless otherwise noted :

Output resistive load = (6) ohms / Both channel driven
Tone Direct ON , Other SW's : OFF
Nominal input level : 5mV for MM, 0.5mV for MC, 500mV for general purpose inputs
Power figures should be kept minimum 10min. between 15 and 35
Terminator : 100ohm for MC, 1kohm for MM and general purpose inputs
Filter : IHF-A filter R/O = Rated Output

Power supply : 120V/60Hz (A), 230V/50Hz (D/E/RDS), 220V/50Hz (C), 220V/60Hz (K)
