ESD protection

Nokia requires that product service points have sufficient
ESD protection (against static electricity) when servicing
products.

Any product of which the covers are removed must be han-
dled with ESD protection. The SIM card can be replaced
without ESD protection if the product is otherwise ready for
use.

To replace the covers ESD protection must be applied.

All electronic parts of the product are susceptible to ESD.
Resistors, too, can be damaged by static electricity dis-
charge.

All ESD sensitive parts must be packed in metallized pro-
tective bags during shipping and handling outside any ESD
Protected Area (EPA).

Every repair action involving opening the product or han-
dling the product components must be done under ESD
protection.

ESD protected spare part packages MUST NOT be
opened/closed out of an ESD Protected Area.

For more information and local requirements about ESD
protection and ESD Protected Area, contact your local
Nokia After Market Services representative.
