1-5. Turning the power off
1.
Turn the computer off.
2.
Press the monitor's POWER button.
The Power LED will disappear.
If the monitor will not be used for a long time, turn off the main power
switch of the monitor, and remove the power plug from the outlet.
1-7. Instructions for attaching a VESA compliant arm
An arm or stand based on the VESA standard (commercially available)
can be attached to the monitor.
Procurement of the arm or stand is at the customer's discretion.
 Arms or stands able to be used
Attachments must satisfy the following.
•  Compatible with the VESA standard.
• Have a gap of 100 mm x 100 mm between the screw holes on the
section to be attached.
•  Not be likely to fall off or break off after being attached to the monitor.
 
How to attach the arm or stand
• Be careful not to over bend the cable or add extension cords as this
could lead to malfunction.
•  While following these instructions, please also refer to the installation
instructions in the operation manual included with the arm or stand.
1.
Remove the cable.
2.
Spread out a soft cloth on a suitable horizontal surface.
3.
Being careful not to damage the monitor, gently lay the monitor on it
display-side down.
4. Remove the four screws and then remove the stand from the moni-
tor.
Note:
•  The stand is specially made for use with this monitor. Once having
removed the stand, never attempt to attach it to another device.
•  Once having removed the screws, store them together with the
stand and if the stand is ever re-attached be sure to use the original
screws.
Using different screws could lead to a malfunction.
5. Attach the arm to the monitor with the four screws.
Note: The screws used to attach the arm should be M4 screws with a
length of 6 mm ~ 8 mm protruding from the surface to be
attached. Using different screws could couse the monitor to fall
off or to be internally danaged.
Caution:
Securely grasp both the display and stand, and gently tip over.
When the monitor is inclined, the stand may suddenly pop out and
cause injury.
OFF
