BATTERY LOW WARNING
If the flashes in the display, you will need to recharge the
handset before you can use it again. During charging, the
will scroll in the display.
BATTERY PERFORMANCE
In ideal conditions, a fully charged battery pack should give
up to 12 hours talk time and up to 180 hours standby time on
a single charge.
Note that new battery packs do not reach full capacity until
they have been in normal use for several days.
To keep your battery packs in the best condition, leave the
handset off the base for a few hours at a time.
Running the battery packs all the way down at least once a
week will help them last as long as possible.
The charge capacity of rechargeable battery packs will
reduce with time as they wear out, giving the handset less
talk/standby time. Eventually they will need to be replaced.
After charging your handset for the first time, subsequent
charging time is about 6-8 hours a day. The battery pack and
handset may become warm during charging. This is normal.
