SAFTY PRECAUTIONS
GENERALS 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 are property installed.。
3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connect a jumper between the two prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between the jumped AC plug and each exposed metallic cabinet part on the equipment
such as screw-heads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis, the reading should be
between 1MΩ and 5.2MΩ. When the exposed metal does not have return path to chassis, the reading must be ∞.

Rolsen RDV-4002/RDV-4003 DVD Service Manual LEAKAGE CURRENT HOT CHECK ( See Figure 1.) 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5KΩ, 10 Watts resistor, in parallel with a 0.15uF capacitors, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1. - Page 3 Rolsen RDV-4002/RDV-4003 DVD Service Manual electro static discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching a known earth ground.

It is essential that these critical parts should be replaced with manufacture’s special parts to prevent shock, fire, or other hazard. - Page 5 Rolsen RDV-4002/RDV-4003 DVD Service Manual Handling of optical pickup Do not subject the optical pickup to static electricity as it is extremely sensitive to electrical shock. To prevent the breakdown of the laser diode, an antistatic shorting pin is inserted into the flexible board (FPC Board).
- Page 6 Rolsen RDV-4002/RDV-4003 DVD Service Manual Grounding for electrostatic breakdown prevention 1、Human body grounding Use the antistatic wrist strap to discharge the static electricity from your body. 2、Work table grounding 3、Put a conductive material (sheet) or steel sheet on the area where the optical pickup is placed and ground the sheet.
