Battery Pack
The following shows statuses and levels available for the battery pack.
Normally the battery status is checked once every five seconds. Taking last immediate ten data of
the power voltage from AD converter, its average is calculated to classify the status into three
levels, either "Almost exhausted (10% of the capacity or less)", "Low (30% of the capacity or
less)", "O.K. (30 % of the capacity or more)". When VDET1 occurs, the level is at 10% of the
capacity.
