Note: No information or user data will be lost if the battery is removed or completely discharged. User data is automatically retained by the flash memory and is unaffected by the status of the battery.

Using the battery

Use only batteries approved by the communicator manufacturer. With approved chargers and acces- sories, the battery can be charged continuously.

The battery need not be fully discharged before recharging. When a charger is not in use, discon- nect it from the power source.

The battery can be charged and discharged hun- dreds of times, but it will eventually wear out. When the operation time (talk-time and stand-by time) is noticeably shorter than normal, it is time to buy a new battery.

Temperature extremes will affect the ability of your battery to charge: it may require cooling or warming first.

Factors affecting battery operation time:

•Whether both interfaces are in use.

•Radio signal strength.

•Various phone settings.

•Length of the communicator interface’s screen power-down period (set in System application’s settings, see Chapter 10 "System: System settings" on page 10-1).

Always keep a charged battery in the communica- tor. Keeping the battery charged maximizes the lifetime of the backup battery supplying power to the communicator’s real-time clock. In the un- likely event that the backup battery is drained, it may be replaced by qualified personnel.

Always close the device cover before removing the battery. Closing the cover automatically saves all data.

Note:

•Use the battery only for its intended purpose.

•Never use any charger or battery which is damaged or worn out.

•Do not short circuit the battery. Accidental short circuiting can occur when contact with a metal object (coin, paperclip or pen) causes direct connection of the + and - terminals of the battery. This could occur when you carry a spare battery in your pocket or purse. Short circuiting the terminals may damage the battery or the connecting object.

•Leaving the battery in hot or cold places, such as in a closed car in summer or winter condi- tions, will reduce the capacity and battery lifetime. Try to keep the battery between +59°F (+15°C) and +77°F (+25°C). A hot or cold battery may temporarily not work, even when the battery is fully charged. Li-Ion batteries’ performance is particularly limited in temperatures below +32°F (0°C).

•Dispose of used batteries in accordance with local regulations. Recycle! Do not dispose of batteries in a fire!
