ONLY)BEFORE RETURNING THE AUDIO PRODUCT(Fire & Shock Hazard)Before returning the audio product to the user, perform thefollowing safety checks.1. Inspect all lead dress to make certain that leads are notpinched or that hardware is not lodged between the chassisand other metal parts in the audio product.2. Inspect all protective devices such as insulating materials,cabinet, terminal board, adjustment and compartment coversor shields, mechanical insulators etc.3. To be sure that no shock hazard exists, check for leakagecurrent 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 resistorparalleled by a 0.15F capacitor in series with all exposedmetal cabinet parts and a known earth ground, such asconduit 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 theresistor (See diagram).* Connect the resistor connection to all exposed metal partshaving 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 tests must be repeated with the AC line cord plug connectionreversed.Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp.AC.) or more is excessive and indicates a potential shockhazard which must be corrected before returning the audioproduct to the owner.FOR A COMPLETE DESCRIPTION OF THE OPERATION OF THIS UNIT, PLEASE REFERTO THE OPERATION MANUAL.AC SCALEVTVM1.5k ohms10W0.15FTEST PROBETO EXPOSEDMETAL PARTSCONNECT TOKNOWN EARTHGROUNDSPECIFICATIONSCD-CH1000CP-RW5000Specifications for this model are subject to changewithout prior notice.I GeneralPower sourceAC 120 V, 60 HzPower consumption175 WDimensionsWidth: 7-7/8 (200 mm)Height: 13-7/8 (352 mm)Depth: 14-7/8 (377 mm)Weight21.4 lbs.
