About your phone

Prolong battery life

A battery lasts longer and performs better if you fully discharge it from time to time. To discharge your battery, leave your phone switched on until the battery drains completely. Ignore any messages to recharge your battery and let the battery completely discharge.

Important: Do not attempt to discharge the battery by any means other than those just described.

SWITCH YOUR PHONE ON OR OFF

To switch your phone on or off, press and hold the power key (located on the

top of the phone) for two seconds.

Power key

Warning! Do not switch on the phone when wireless phone use is prohibited or when it may cause interference or danger.

• CHECK THE START SCREEN

The Start screen refers to the phone’s display when no calls are in progress, and there are currently no menu or phone book entries displayed.

You can easily return to the Start screen from any location (other than an active call) simply by

pressing the key. However, keep in mind that any text or numbers that you were entering at the time will be lost, and your work will not be saved.
