If a program cannot be shut down even by
the Task Manager when it has stopped
running, or if DOT 400 cannot be
synchronized despite several attempts to
access the desktop PC, Carry out software
reset by quickly pressing the Reset button
on the bottom of DOT 400.
To software reset DOT 400, the Reset
button should be pressed for less than a

lost.
Hardware
reset
If DOT 400 does not respond to any input,
nor can the problem be solved by software
reset, You must perform hardware reset.
To hardware reset DOT 400, press the
Reset button on the bottom of DOT 400
and hold it for more than 4 seconds. Then,
DOT 400 battery power is shut down and
DOT 400 becomes down. Press the Reset
button again shortly, then DOT 400 is
connected to the battery power and DOT
400 is hardware reset.
Since the hardware reset will result in loss
of all files and data, it is recommended
that the data and files stored in DOT 400
should be backed up periodically in the
desktop PC, CF memory card, or flash
ROM.
Reset by
battery fault
If DOT 400 does not work due to full
discharge of the battery, it should be
recharged using the battery charger. Do
not attempt to operate DOT 400 when its
battery is completely discharged. When the
battery is recharged, DOT 400 will be
hardware reset automatically.
