Page 3: Safety Precautions
SC-EN38P / SC-EN38PC 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, ensure that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
Page 4 SC-EN38P / SC-EN38PC 1.2. Before Repair and Adjustment Disconnect AC power, discharge Power Supply Capacitors C501 and C502 through a 10Ω, 1W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.

SC-EN38P / SC-EN38PC 2 Prevention of Electro Static Discharge (ESD) to Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by electricity. Such components commonly are called Electrostatically 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
SC-EN38P / SC-EN38PC 3 Precaution of Laser Diode CAUTION: This unit utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pickup lens. When the unit is turned on: 1. Do not look directly into the pick up lens.
Page 7: Handling Precautions For Traverse Deck
SC-EN38P / SC-EN38PC 4 Handling Precautions For Traverse Deck The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
