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:

• A mobile terminal 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 mobile terminal
covers which can be replaced by the customer.

• All electronic parts of the mobile terminal, 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 mobile terminal or handling the mobile
terminal 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.
