Page 3: Safety Precautions
1 Safety Precautions 1.1. General Guidelines 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed. -
Page 4: Before Repair And Adjustment
1.2. Before Repair and Adjustment Caution : DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid overcurrent. • Current consumption at AC 230V, 50Hz in TUNER mode at volume (min) should be (~300 mA). 1.3. -
Page 5: Warning
2 Warning 2.1. Prevention of Electro Static Discharge (ESD) to Electrostatically Sensi- tive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor “chip”... -
Page 6: Precaution Of Laser Diode
2.2. Precaution of Laser Diode CAUTION! THIS PRODUCT UTILIZES A LASER. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. Caution: This product utilizes a laser diode with the unit turned "on", invisible laser radiation is emitted from the pickup lens. Wavelength: 795 nm (CD) Maximum output radiation power from pickup: 100 μW/VDE Laser radiation from the pickup unit is safety level, but be sure the followings:... -
