<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.
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.
Cosmetic screws
Screwsa4
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.
