4. ESD PROTECTION
Nokia requires that service points have sufficient ESD protection (against
static electricity) when servicing the phone.
Any product of which the covers are removed must be handled 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 discharge.
All ESD sensitive parts must be packed in metallized protective bags during
shipping and handling outside any ESD Protected Area (EPA).
Every repair action involving opening the product or handling 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.
