Battery Pack
The following shows statuses and levels available for the battery pack.
Normally the battery status is checked once every five seconds. However, it will be performed
every second when the power management property is displayed. Taking last immediate ten data
of the power voltage from AD converter, its average is calculated to classify the status in three
levels, either “Almost exhausted (10 % of the capacity or less)”, or “Low (30 % of the capacity or
less)”, or “O.K. (30 % of the capacity or more)”. The level is 10 % of the capacity when VDET1
