2 Connect the charger to the proper voltage AC wall outlet. While
charging is in progress, the battery charge indicator scrolls on the display.
To use the battery
Use only batteries approved by the communicator manufacturer and
recharge the battery only with the chargers approved by the
manufacturer. With approved chargers and accessories, the battery can
be charged continuously. The battery need not be fully discharged before
recharging. When a charger is not in use, disconnect it from the power
source. Do not leave the battery connected to a charger for longer than a
week, since excessive charging may shorten its life. If left unused, a fully
charged battery will discharge itself over time.
The battery can be charged and discharged hundreds of times, but it will
eventually wear out. When the operating time (talk–time and standby
time) is noticeably shorter than normal, it is time to buy a new battery.
Note: The communicator can be used normally during charging.
Temperature extremes will affect the ability of your battery to charge:
allow it to cool down or warm up first.
Battery operation time is affected by the following: whether both the
phone and the communicator interface are on, radio signal strength,
various phone settings, the use of the backlight, and the length of the
screen blanker period.
It is recommended always to keep a charged battery in the communicator.
Keeping the battery charged maximises the lifetime of the backup battery
supplying power to the real–time clock of the communicator. In case the
backup battery is drained, it will be automatically charged the next time a
charged battery is reconnected to the communicator.
Always close the device cover before removing the battery. Closing the
cover will save all data.
Note
Use the battery only for its intended purpose.
Never use any charger or battery that is damaged or worn out.
Do not short–circuit the battery. Accidental short–circuiting can occur
when a metallic object (coin, clip or pen) causes direct connection of the +
and –terminals of the battery (metal strips on the back of the battery), for
example, 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 conditions, will reduce the capacity and lifetime of the
battery. Always try to keep the battery between +15
°
C (+59
°
F) and +25
