WARNING

All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.

ESD

CLASS 1

LASER PRODUCT

GB

Safety regulations require that the set be restored to its original
condition and that parts which are identical with those specified,
