Moving and Lifting the Monitor

When moving or lifting the monitor, follow these
instructions to prevent the monitor from being
scratched or damaged and to ensure safe trans­portation, regardless of its shape or size.

yPlace the monitor in the original box or pack-

yBefore moving or lifting the monitor, discon-

nect the power cord and all other cables.

yHold the bottom and side of the monitor frame

firmly. Do not hold the panel itself.

yWhen moving the monitor, keep it upright and

never turn the monitor on its side or tilt it side­ways.

yAvoid touching the monitor screen as much as

possible.

- This may result in damage to the screen or
some of the pixels used to create images.

base, its joystick button may cause the moni­tor to become unstable and fall, resulting in
damage to the monitor or human injury. In
addition, this may cause the joystick button to
malfunction.
