MINI COMPONENT SYSTEM

MODEL CD-E800

CD-E800 Mini Component System consisting of CD-E800 (main unit) and CP-E800 (speaker system).

• In the interests of user-safety the set should be restored to its original condition and only parts identical to those specified be used.

This Serivce Manual is for the CD-E800/CD-E88, which is a

minor-modification model of the CD-E700/CD-E77, This manual, therefore, describes only the changed points from the service manual. Pleasa refer to the CD-E700/CD-E77, service manual (No. S1301CDE700//) together with this manual.

IMPORT ANT SER VICE 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 1.5 kohm, 10 watt resistor

paralleled by a 0.15 µF 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.

TEST PROBE

METAL PARTS

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.
