6. Do not remove a replacement ES device from its protective
package until immediately before you are ready to install it. (Most
replacement ES devices are packaged with leads electrically
shorted together by conductive foam, aluminium foil or
comparable conductive material).
7. Immediately before removing the protective material from the
leads of a replacement ES device, touch the protective material to
the chassis or circuit assembly into which the device will be
installed.
Caution
Be sure no power is applied to the chassis or circuit, and observe
all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement
ES devices. (Otherwise harmless motion such as the brushing
together of your clothes fabric or the lifting of your foot from a
carpeted floor can generate static electricity (ESD) sufficient to
damage an ES device).
7. Cautions to Be Taken When Handling Optical
Pickup
- The laser diode used inside the optical pickup could be destroyed
due to static electricity (potential difference is caused by
electrostatic load discharged from clothes and human body).
Handle the parts carefully to avoid electrostatic destruction during
repair & during replacement.
7.1. Handling Optical Pickup
1. Do not cause any strong impact on optical pickup as the unit
structurally uses an extremely precise technology.
2. Short-circuit the flexible cable of optical pickup removed from the
circuit board using a short-circuit pin or clip in order to prevent
laser diode from electrostatic destruction. (Refer to
