HANDLING CHIP COMPONENTS

WARNING
GB
All ICs and manyother semi-conductors are
susceptible to electrostatic discharges(ESD).
Careless handling during repaircan reduce life
drastically.
When repairing, make surethat you are
connected with the samepotential as the mass
of the setvia a wrist wrap with resistance.
Keep components andtools also at this
potential.
CLASS 1
LASER PRODUCT
ATTENTION
GB
Safety regulations requirethat the set be restored to its original
condition and thatparts which are identical with thosespecified,
be used.

AVVERTIMENTO
Tutti IC eparecchi semi-conduttori sono
sensibili alle scariche statiche(ESD).
La loro longevita potrebbeessere fortemente
ridatta in casodi non osservazione della piu
