Power
The monitor should be operated only from the type of power source indicated on the label. If you are
not sure of the type of power supplied to your home, consult your dealer or local power company.
The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin.

the three-wire plug, have an electrician install the correct outlet, or use an adapter to ground the appliance
safely. Do not defeat the safety purpose of the grounded plug.
Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will
protect the monitor from damage due to power surges.

Do not place the monitor on an unstable cart, stand, tripod, bracket, or table. If the monitor falls, it can
injure a person and cause serious damage to this product. Use only a cart, stand, tripod, bracket, or table
recommended by the manufacturer or sold with this product. Follow the manufacturer’s instructions when
installing the product and use mounting accessories recommended by the manufacturer. A product and
cart combination should be moved with care.

If you mount the monitor on a wall or shelf, use a mounting kit approved by the manufacturer and
follow the kit instructions.
Leave some space around the monitor as shown below. Otherwise, air-circulation may be inadequate

To avoid potential damage, for example the panel peeling from the bezel, ensure that the monitor does
not tilt downward by more than -5 degrees. If the -5 degree downward tilt angle maximum is exceeded, the
monitor damage will not be covered under warranty.
See below the recommended ventilation areas around the monitor when the monitor is installed on the wall

Other
If the product is emitting a strange smell, sound or smoke, disconnect the power plug IMMEDIATELY
and contact a Service Center.
Make sure that the ventilating openings are not blocked by a table or curtain.
Do not engage the LCD monitor in severe vibration or high impact conditions during operation.
Do not knock or drop the monitor during operation or transportation.
IThe power cords shall be safety approved. For Germany, it shall be H03VV-F, 3G, 0.75 mm2, or better. For
other countries, the suitable types shall be used accordingly.
IExcessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the
equalizer to maximum increases the earphones and headphones output voltage and therefore the sound
pressure level.

Adjusting Viewing Angle
To achieve the best viewing experience, it is recommended that the user can make sure they are able to look
at their whole face on the screen, then adjust the monitor’s angle based on personal preference.
Hold the stand so you will not topple the monitor when you change the monitor’s angle.
You are able to adjust the monitor as below:
130mm
30°
30°
90°
90°
NOTE:
Do not touch the LCD screen when you change the angle. It may cause damage or break the LCD screen.
WARNING:
1. To avoid potential screen damage, such as panel peeling, ensure that the monitor does not tilt downward
by more than -5 degrees.
2. Do not press the screen while adjusting the angle of the monitor. Grasp only the bezel.
