•Before plugging the unit into a power outlet, ensure that the outlet
provides the same type and level of power required by the device.
•Take care to prevent damage to the power cord. Do not allow it to
become crimped, pinched, walked on, or become tangled with other
cords. Ensure that the power cord does not present a tripping hazard.
•Never unplug the unit by pulling on the power cord. Always grasp the

in". Alternatively, ensure that the monitor is powered off for at least 2
hours out of every 12.
