Power source
This LCD display operates on 120 volts 60 Hz, AC current. Insert the power
cord into a 120 volts 60 Hz outlet. The mains plug is used as the disconnect
device and shall remain readily operable.
To prevent electric shock from the display, do not use with an extension cord,
receptacle, or other outlet unless the blades and ground terminal can be fully
inserted to prevent blade exposure.
Never connect the LCD display to 50 Hz, direct current, or anything other than
the specified voltage.
CAUTION: Never remove the back cover of the LCD display as this can
expose you to very high voltages and other hazards. If the display does not
operate properly, unplug the LCD display and call your authorized dealer or
service center.
Adjust only those controls that are covered in the instructions, as improper
changes or modifications not expressly approved by NEC could void the
user’s warranty.
