How do I form a factory reset on the Tascam DR-1 portable recorder?

The back panel of the unit has a reset hole.
If the unit is operating abnormally, push the end of
a paperclip or similar item into this hole to press a
button inside the unit. This turns the power OFF and
resets the DR-1’s system.
CAUTION
Do not press the reset button when the unit is
functioning properly.
