Cosmetic screws
A total of eight cosmetic screws are provided with the
monitor for use at such times when the main controls have
been relocated. (Refer to page 9)
Since these screws also serve to protect the internal
mechanisms, do not leave the screw holes empty but place
the screws inside them and tighten them up. Any screws
which are not being used should be kept in a safe place.

supply
If an external DC power supply is used, then check the
ratings of the external DC power supply so that they
are compatible with those of this unit.
Check the pin arrangements of the DC output terminal
of the external DC power supply and those of the DC
IN socket of this unit so that their polarities are
correctly arranged.
If +12 V are supplied to the unit’s GND terminal by
mistake, this may cause fire or injury.
<Notes>
≥DC cords should be no longer than 2 meters. Use of cords
any longer than 2 meters may result in noise appearing on
the screen.
≥If the battery pack and an external DC power supply are
connected simultaneously, then the external DC power
supply will have priority.
If the external DC power supply is used, then the battery
pack may be fitted or removed.
≥If an external DC power supply is used, then make sure
that the external DC power supply is first turned ON, then
this unit is turned ON. If they are turned ON in the reverse
order, then this unit may malfunction, because the output
voltage of the external DC power supply will gradually
increase.
≥A voltage of 20 V or more will not be indicated accurately
on the battery voltage display.
