Getting Started

Battery Use

Battery performance depends on many factors, including your

wireless carrier’s network configuration; signal strength; the

temperature at which you operate your phone; the features

and/or settings you select and use; and your voice, data,

and other application usage patterns.

Battery Care

Caution: To prevent injuries or burns, do not allow metal objects

to contact or short-circuit the battery terminals.

To maximize performance:

• Always use Siemens Original batteries and battery

chargers. The phone warranty does not cover damage

caused from using non-Siemens batteries and/or battery

chargers.

• New batteries or batteries that have been stored for long

periods of time may require a longer charge time.

• Maintain the battery at or near room temperature when

charging.

• When you do not intend to use a battery for a while, store it

uncharged in a cool, dark, dry place, such as a refrigerator.

• Over extended periods of time, batteries gradually wear

down and require longer charging times. This is normal. If

you charge your battery regularly and notice a decrease in

talk time or an increase in charging time, then it is probably

time to purchase a new battery.

The rechargeable batteries that power this product

must be disposed of properly and may need to be

recycled. Refer to your battery’s label for battery type.

Contact your local recycling center for proper disposal

methods. Never dispose of batteries in a fire because they may

explode.
