Page 92: Precautions
PRECAUTIONS ** To prevent the risks of unit damage, electrical shock and radiation, take the following safety, service, and ESD precautions. Handling Precautions for Plasma Display – PDP module use high voltage that is dangerous to human. Before operating PDP, always check the dust to prevent circuit short.
Page 93 – Must use a soldering device for ground-tip when soldering or de-soldering ESD. – Must use anti-static solder removal device. Most removal device do not have antistatic which can charge a enough positive electric enough damaging ESD. – Before removing the protective material from the lead of a new ESD, bring the protective material into contact with the chassis or assembly that the ESD is to be installed on.
