Notes:
If the application receives the low battery warning message (PBT_APMBATTERYLOW),
the application should reset the Virtual OFF mode and warn the user of low battery. If the
user continues to operate the terminal ignoring resetting the Virtual OFF mode, turning off
the power will occur (ordinal process to turn off the power) due to low voltage of the battery.
This causes a confusion and makes the user unable to judge whether the terminal cannot
resume from the Virtual OFF mode or troublesome caused by the battery ran out.
During the Virtual OFF mode, if low battery or turning off the power by opening the battery
cover lock switch occurs, there will be discrepancy between the expected condition the
application assumes at the next time of starting up and actual condition. For turning off the
power in ordinary process, the discrepancy is caused by two kinds of setting, one should be
reset and the other to be saved. These settings must be set to ON state again in the Virtual
OFF mode when the application receives the Power On message
(PBT_APMRESUMESU|SPEND).
