In order to protect the circuitry, the battery cannot
be charged if the unit is in a location exposed to
extremely high or extremely low temperatures.
Do not wind the AC adapter cable around the adapter
or bend the cable, otherwise the cable may be dam-
aged.
It takes approximately three hours for the battery
to be recharged from completely empty to fully
charged (with the printer turned off).
