Foreword

ESD Protection

Nokia requires that phone repair places have sufficient ESD protection
(against static electricity) when servicing cellular phones.
A cellular phone, which is ready for use, can be handled normally without
ESD protection. The SIM card and battery can be replaced in normal
conditions of use.
To replace the color cover ESD protection must be applied, except for the
phone covers which can be replaced by the customer.
All electronic parts of the phone , including the display, 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 phone or handling the phone
components must be done under ESD protection.
ESD protected spare part packages MUST NOT be opened/closed out of an
EPA.
For more detailed information about ESD protection and EPA, contact your
local Nokia After Market Services representative.
