When disconnecting
the power cable,
be sure to grasp
it by the plug.
Never pull on the
connecting cord
itself, as doing so
increases the risk
of malfunction.
Do not drop the unit
into water. When
disconnecting the
connector on the
back side,
be sure it does
not get wet, as
doing so increases
risk of electrical shock or
malfunction.
Do not use or
install the unit
in a place where
the LCD is subject
to direct
sunlight, or in
a location near
heat sources
where the temperature
is 50°C (Display Unit), 55°C (Scanner
Unit) or more.
Doing so may cause a malfunction
or defect.
Do not turn on the unit immediately
after moving it from a cold place to a
warm one. Let the unit stand for
around 30 minutes before turn on,
until the inside temperature of the
unit reaches the same level as that of
the room it was moved to.
Not doing so increases risk of
malfunction.
