Page 3: Safety Precautions
1 Safety Precautions 1.1. General Guidelines 1. IMPORTANT SAFETY NOTICE There are special components used in this equipment which are important for safety. These parts are marked by in the Schematic Diagrams, Circuit Board Layout, Exploded Views and Replacement Parts List. It is essential that these critical parts should be replaced with manufacturer’s specified parts to prevent X-RADIATION, shock, fire, or other hazards. -
Page 4: Caution For Ac Cord (Gs/Gsx Only)
1.2. Caution for AC Cord (GS/GSX only) 1.3. Before Repair and Adjustment Disconnect AC power, discharge AC Capacitors (C1702, C1710, C1725, C1727 and C1728) through a 10W, 1W resistor to ground. 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. -

Page 6: 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. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD). -
Page 7: 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: 790 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:... -
Page 8: Handling Precaution For Traverse Unit
2.4. Handling Precaution for Traverse Unit The laser diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must be taken avoid caution to electrostatic breakdown when servicing and handling the laser diode in the Traverse Unit. Cautions to Be Taken in Handling the Optical Pickup Unit 2.4.1. - Page 9 Grounding for electrostatic breakdown prevention 2.4.2. Some devices such as the CD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electricity in the working environment. Proceed servicing works under the working environment where grounding works is completed. 2.4.2.1.
