CAUTION
Handling of Electrostatic--sensitive Semiconductor Devices
Certain semiconductor devices used in the equipment are liable to damage due to static
voltage. Observe the following precautions when handling these parts or sub--units of
the system components which, because of the now open inputs of the semiconductor
devices, are endangered by static charge.
1) Persons removing sub--units from an equipment using these devices must be earthed
by a wrist strap and a resistor at the point provided on the equipment.
2) Soldering irons used during the repair operations must be low voltage types with
earthed tips and isolated from the mains voltage by a double insulated transformer.
3) Outer clothing worn must be unable to generate static charges.
4) Printed Circuit Boards (PCBs) fitted with these devices must be stored and trans-
ported in anti--static bags.
PCBs are to be laid down on non--conducting surfaces free from static charge only!
