nents are sensitive to, and easily affected by, static electricity. If such static electricity is high voltage,
components can be damaged, and for that reason components should be handled with care.

must be taken, therefore, to avoid repair or storage where the temperature of humidity is high, where
strong magnetism is present, or where there is excessive dust.
2. Notes for repa
ir
1) Before replacing a component part, first disconnect the power supply lead wire from the unit
2) All equipment, measuring instruments and tools must be grounded.

When removing the laser pick-up from its conductive bag, do not place the pick-up on the bag.
(This is because there is the possibility of damage by static electricity.)
4) To prevent AC leakage, the metal part of the soldering iron should be grounded.
5) Workers should be grounded by an armband (1M )

prevent static electricity changes in the clothing to escape from the armband.
7) The laser beam from the pick-up should NEVER be directly facing the eyes or bare skin.
