CHAPTER 1. GENERAL DESCRIPTION

[1] 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 or

that hardware is not lodged between the chassis and other metal

parts in the audio product.

2. Inspect all protective devices such as insulating materials, cabinet,

terminal board, adjustment and compartment covers or shields,

mechanical insulators etc.

3. 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 1.5k ohm, 10 watt resistor paral-

leled by a 0.15µF 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).

* 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.

All check must be repeated with the AC line 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.
