This device contains electrostatically sensitive components. Damage can occur to these components if the appropriate handling is not adhered to.

ESD Handling precautions:

A working area in which Digital Cellular Telephones may be safely handled without undue risk of damage from electrostatic discharge must be available.

The area must be equipped as follows:

All working surfaces must have a dissipative bench mat, safe for use with live equipment, connected via 1.2M resistor to a common ground point.

A quick release skin contact device with a flexible cord, which has a built-in safety resistor of a range between 5.2K and 1.2M shall be used. The flexible cord must be attached to a dissipative earth point.

All containers and storage must be of the conductive type.
