Preparations
Power
The unit can be powered by four IEC R6, size AA batteries (alkaline), the
optional AC adapter NC-98 series, and the optional battery pack BP-21A.
Rechargeable nickel metal-hydride batteries may also be used, but the unit
does not have a facility for charging the batteries.
WARNING
If the unit is heated during use or the unit
produces smoke or smell of burning, im-
mediately remove the batteries from the
unit or disconnect the AC adapter plug
from the outlet, and then contact your
supplier.
Note
When the AC adapter is connected, the unit will be
powered from the adapter, also when batteries are
inserted. (The AC adapter has priority.)
In case of a power failure or other interruption of AC
power, the unit will automatically switch to battery
power and continue operation.
When the unit is operated on external power only, the
fi le auto close function and auto shutdown function
will not be executed. We recommend that new batteries
be set in the unit.
The unit responds to the momentary stop up to 50 ms.
