Power Saving Function
This display meets the power saving guidelines set by the International
ENERGYSTAR Program. It is capable of reduced power consumption when
usedwithacomputerequippedwithDisplayPowerManagementSignaling
(DPMS). By sensing the absence of the sync signal coming from the computer,
it will reduce the power consumption as follows:

Warning on Power Connection
· Use the supplied power cord.
For the customers in UK.
If you use the display in UK, please use the supplied UK cable with UK plug.
for 100 to 120 V AC
for 220 to 240 V AC
for 240 V AC only
· Before disconnecting the power cord, wait at least 30 seconds after turning
off the power switch to discharge static electricity from the CRT display
surface.
· After the power has been turned on, the CRT is demagnetized for
approximately 5 seconds. This generates a strong magnetic field around the
bezel which may affect the data stored on magnetic tape or disks near the
bezel. Place such magnetic recording equipment and tapes/disks at a distance
from this unit.
The socket-outlet shall be installed near the equipment and shall be easily
accessible.
