ESD Protection

Nokia requires that phone repair centers have sufficient ESD protection against static
electricity when servicing cellular phones. Use the following guidelines:
• A cellular phone that is ready for use can be handled normally without ESD
protection. The battery can be replaced in normal conditions of use.
• Use ESD protection when replacing a color cover, 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 also 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 outside an EPA.
For more detailed information about ESD protection and EPAs, contact your local Nokia
Customer Care representative.
