electrical charge to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical
charges sufficient to damage ES devices.
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 body 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).
3. Precaution of Laser Diode
Caution :
This product utilizes a laser diode with the unit turned "ON", invisible
laser radiation is emitted from the pick up lens. / Wavelength : 780 nm /
Maximum output radiation power from pick up : 100 W/VDE / Laser
radiation from pick up unit is safety level, but be sure the followings:
1. Do not disassemble the optical pick up unit, since radiation from
exposed laser diode is dangerous.
2. Do not adjust the variable resistor on the pick up unit. It was already
adjusted.
3. Do not look at the focus lens using optical instruments.
4. Recommend not to look at pick up lens for a long time.
