Safety Information

Adhere to the following guidelines when assembling and disassembling the mobile terminal.
•QUALIFIED SERVICE Only qualified personnel may install or repair mobile terminal equipment.
ACCESSORIES AND BATTERIES Use only approved accessories and batteries. Do not connect incompatible products.
CONNECTING TO OTHER DEVICES When connecting to any other device, read its user’s guide for detailed safety instructions. Do not connect incompatible products.

ESD Protection

Nokia requires that mobile terminal repair centers have sufficient ESD protection against static electricity when servicing mobile terminals. Use the following guidelines:

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.
