1 Precautions 1 Precautions Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as electrical shock. 1-1 Safety Precautions 1-1-1 Warnings 1. For continued safety, do not attempt to modify the circuit board. 2. Disconnect the AC power and DC power jack before servicing. 2. It is essential that service technicians have an accurate voltage meter available at all times. Check the calibration of this meter periodically.
1 Precautions 1-2 Servicing Precautions WARNING: An electrolytic capacitor installed with the wrong polarity might explode. Caution: Before servicing units covered by this service manual, read and follow the Safety Precautions section of this manual. Note: If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precautions.
1 Precautions 1-4 Installation Precautions 1. For safety reasons, more than two people are required for carrying the product. 6. Keep the antenna far away from any high-voltage cables and install it firmly. Contact with the highvoltage cable or the antenna falling over may 2. Keep the power cord away from any heat emitting cause fire or electric shock. devices, as a melted covering may cause fire or electric shock. 7.
