8.2.5.2 Power monitoring
The MP2500 monitors battery voltage and displays power warnings when
this drops below a fixed threshold. Users cannot monitor power levels. The
MP2500 does not support fast charging. Once charging is detected by
inserting the charger, a constant current appropriate for the battery type will
flow for a maximum time of 8.5 hours (for a NiCd battery) or 12 hours (for a
NiMH battery) after which the charge current will drop to a maintenance
charge (NiCd) or zero (NiMH). This enables both NiCd and NiMH batteries
to be left on charge safely for long periods.
For information on using the HOT key to set up the power options, see
section 11.5.
8.2.5.3 Low Battery Warning
The MP2500 is designed to provide adequate warning of impending battery
failure and will protect user's data, even in the worst situations.
Warnings are given when the battery voltage is getting low. The low power
warning message is displayed on the top line of the screen and looks like
this:
WARNING BATTERY LEVEL LOW
The MP2500 bleeps to draw attention to the warning, displays it for a few
seconds, then restores the original display until the next warning. Warnings
are displayed every 10 seconds.
Since it is usually essential that all data and programs are preserved, the
user should save any files disk and switch off as soon as practical and
either replace the batteries with a fresh set or, if rechargeable batteries are
fitted, put them on charge.
If the user does not turn off, the warnings will be repeated every 10
seconds. After ten consecutive warnings, the MP2500 will switch off
automatically (unless overridden by your application).
When power is restored, program execution will continue from precisely
where it was prior to the interruption.
