Connect the charger to an AC wall outlet. If
the phone interface is switched on, the
CHARGING message appears on the display
and segments of the battery indicator bar on
the right-hand side of the phone interface
display will start scrolling. (Charging informa-
tion is also shown on the communicator in-
terface display, see "Indicators: Using the
applications".)
When the battery is fully charged (the bars stop
scrolling and five bars are displayed), you may
remove the adapter from the communicator:
Hold down the release button on the left side
of the adapter (see figure 2-7), and turn the
adapter away from the communicator.
When the charge is low and only a few minutes
of operation time remain, a warning tone will be
heard, and the message BATTERY LOW will be re-
peated at regular intervals on the display. When
the charge level becomes too low for operation,
the RECHARGE BATTERY message will be dis-
played, accompanied by a warning tone. If you do
not connect the communicator to a charger, the
communicator automatically switches itself off.
Note: If the tones have been switched off (see
chapter 14 "Phone interface: Menus - All sounds
(Menu 10)"), only the display messages will appear.

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.
Battery operation time is affected by the follow-
ing: whether both interfaces are on, radio signal
strength, various phone settings, and the length
of the communicator interface's screen blanker
time-out period (set in System application's set-
tings, see chapter 10 "System: System settings").
It is recommended always to keep a charged bat-
tery in the communicator. Keeping the battery
charged maximises the lifetime of the backup bat-
tery supplying power to the communicator's real-
time clock. In case the backup battery is drained,
it may be replaced by qualified personnel.
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 which 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, 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 condi-
tions, will reduce the capacity and lifetime of
the battery. Always try to keep the battery
between +15°C (+59°F) and +25°C (+77°F). A
communicator with 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
0°C (+32°F).
• Dispose of used batteries in accordance with
local regulations. Recycle! Do not dispose of
batteries in a fire!
