WORKING ON BATTERIES; BATTERY lOW
INDICATOR
You will be informed in two ways that the batteries have
become discharged:
1. The battery indicator light beside the display (40,8)
comes on.
2.
An acoustic signal is emitted through the speaker
(4O,A) (5 beeps), at short intervals.
When the battery indicator light comes on and you hear the
acoustic signal, this means that the batteries have become
discharged and there remains between one and five minutes
of battery power. The exact time remaining depends on the
age of the batteries and on the working conditions (hard
disk on/off, backlight on/off etc.).
BATTERY OPERATION, CHARGING UP THE
BATTERIES
When the battery indicator light ca.es on, it is very
i~ortant to take the following steps i..ediately:
1. Switch off the backlight to save battery power.
2. Bring your
current work session to a close.
3. Avoid as far as possible all activities which involve
long read/write operations on the disk drive(s)/hard
disk. (For example: do not execute the FORMAT
command.)
4. Store all your data.
5. Switch the system off.
If your system is equipped with a hard disk: switch the
hard disk off.
