  • Page 2: 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 3: Before Repair And Adjustment

    1.2. Before Repair and Adjustment This model uses switching mode power supply (SMPS) module to provide the necessary voltages for the Digital Receiver 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.
