IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)

BEFORE RETURNING THE AUDIO PRODUCT

(Fire & Shock Hazard)

Before returning the audio product to the user, perform the

following safety checks.

1. Inspect all lead dress to make certain that leads are not
pinched orthat hardware is not lodged between the chassis
and other metal parts in the audio product.

. Inspect all protective devices such as insulating materials;
cabinet, terminal board; adjustment and compartment
covers or shields, mechanical insulators etc.

. To be sure that no shock hazard exists, check for leakage
current in the following manner.

Plug the AC line cord directly into a 120 volt AC outlet.
Using two clip leads, connect a 15K ohm, 10 watt resistor
paralleled by a 0.15uF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).

To EXPOSED GROUND

METAL PARTS
Connect the resistor connection to all exposed metal parts
having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.
Allcheckmust be repeated with theACline cord plug connection
reversed.
Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp.
AC.) or more is excessive and indicates a potential shock
hazard which must be corrected before returning the audio
product to the owner.
