IMPORTANT SERVICE NOTES (FOR GX-CD30/130 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 VTVM
pinched orthat hardware is not lodged between the chassis 0AC SCALEO
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials, 1.5k ohms
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.
10W
-l
Plug the AC line cord directly into a 120 volt AC outlet. 015 H F
Using two clip leads, connect a 1.5k ohm, 10 watt resistor TEST pRoBE CONNECT TO
paralleled by a 0.15pF capacitor in series with all exposed TO EXPOSED KNOWN EARTH
metal cabinet parts and a known earth ground, such as METAL PARTS
R ND
conduit or electrical ground connected to earth ground. G 0U
" 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.

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.
