Maintenance
Since the expansion CF card consumes a
huge amount of power, use the external
power source whenever possible. Remove
the expansion CF card when not in use.
When connecting to the desktop PC,
connect the battery charger to DOT 400
power jack or the docking cradle for
recharging.
When DOT 400 is not in use, set DOT 400
to enter into the automatic suspend mode
or press the power button to turn DOT 400
off.
