<Notes>
Use a shield cable with a length of 2 m (6.56 feet)
or less for the DC cord. Use of cords any longer
than 2 m (6.56 feet) 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.
Input voltage that above the specification is not
displayed accurately.
