8. POWER SUPPLY
The power supplied for the printer is either from the AC Adapter or the alkaline batteries. When the
AC adapter is used while the alkaline batteries are installed, the power will be supplied from the AC
adapter.
When the power to the printer is turned off, all the statistical calculation data stored
in memory will be erased. Also, if the AC adapter is connected/disconnected while
the printer is operating (disregarding whether the printer is operated by the AC
adapter or the batteries), the data accumulated may be erased.
