Certain semiconductor devices used in the equipment are liable to damage due to
static voltage. Observe the following precautions when handling these devices in their
unterminated state, or sub-units containing these devices:
Persons removing sub-units from an equipment containing these devices must be
earthed by a wrist strap and a resistor at the point provided on the equipment.
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.
Outer clothing worn must be unable to generate static charges.
Printed Circuit Boards (PCBs) fitted with these devices must be stored and
transported in anti-static bags.
Fit new devices in a special handling area.
For detailed information, refer to IEC Standard IEC 61340-5-1:1998 or other
equivalent standard.
