To measure the lifetime of the battery
The remaining lifetime of the battery is measured more precisely
by using the battery type setting on the H4n.
Saving period for the setting <DATE/TIME>
Whenever power supply is off by dead battery, the H4n can save
the date/time setting for three minutes. When the saving time is
over, the setting will be returned to the default value.
