15、ENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/

16、or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If

17、 you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food.

26、RGE The laser diode in the DVD mechanism may be damaged due to static electricity from clothes or the human body. Use caution to prevent electro static damage when servicing or handling the DVD-mechanism. 1. Grounding for electro static damage prevention Some devices, such as the DVD player, use an

27、optical pickup (laser diode) that will be damaged by static electricity in the working environment. Only attempt service after ensuring that all grounding procedures have been completed. 1. Worktable grounding Put a grounded conductive material (sheet) or iron sheet on the area where the optical pic

28、kup is placed. 2. Human body grounding Use an anti-static wrist strap to discharge the static electricity from your body. 1M Conductive material (sheet) or steel sheet Anti-static wrist strap 2. Handling Precautions for DVD mechanism 1. Handle the DVD mechanism gently, as it is an extremely high-pre

29、cision assembly. 2. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable. 3. The semi-fixed resistor for laser power adjustment should not be adjusted. Do not turn the resistor. Warning for power supply The primary side of the power supply ca
