■■■■SERVICE PRECAUTION
[OVERCURRENT PROTECTION ELEMENT FOR USB OUTPUT OF THE POWER UNIT]
The USB output (5V, connector CN2) of the power unit is provided with an overcurrent protection element (Part Number PTC101) of PTC (positive
characteristics thermister). Its resistance becomes high when heated by an overcurr ent, and shuts down the circuit similarly with a fuse. When it is
cooled down by non-conduction, its resistance returns to a low level and allows a current to flow through the circuit.
If a user erroneously allows an overcurrent to flow through an USB device, the PTC101 cuts off the current. When repaired, it returns to normal. Note
this operation of the PTC 101 in case of an USB error.

Power management
The monitor is based on the VESA DPMS*1 and the DVI DMPM*2 standards.
To activate the monitor's Power Management function, both the video
card and the computer must conform to the VESA DPMS standard and
the DVI DMPM standard.
This monitor supports the VESA DDC (Display Data Channel) standard.
DDC is a signal standard for carrying out Plug & Play functions on the
monitor or PC. It transfers information such as degree of resolution
between the monitor and PC. You can use this function if your PC is
DDC compliant and if it is set so that it can detect the Plug & Play monitor.
There are many varieties of DDC due to the differences between systems. This monitor works with DDC2B.

The display can be rotated for a long height or width to suit the displayed content.
• Before rotating, move the display to its uppermost position. If the display is rotated while it is set low, it will contact the stand and could
lead to damage.
• The display can only be rotated through a range of 90°. Applying
excessive force may cause malfunction.
• Do not apply excessive force when the cable is connected.
To set to long height
Gently turn in the clockwise direction (to 90°).
To set to long width
Gently turn in the counterclockwise direction (to 90°).

CHAPTER 2. CONNECTION, ADJUSTMENT, OPERATION, AND FUNCTIONS
1. CONNECTING THE MONITOR AND TURNING THE MONITOR ON AND OFF
Caution: • When connecting, ensure that both the monitor and com-
puter are switched off.
• Be careful not to overly bend the cable or add extension
cords as this could lead to malfunction.
Cable storage
If necessary, excess cable can be housed in the stand.
1. Remove the cover.
Gently pull the top of the cover towards yourself.
2. Run cable along the back of the stand.
Pass cable in front of the stand, and then bring it through the back.
CONNECTING THE MONITOR TO A COMPUTER
Connecting using accessory analog signal cable
Connect the accessory analog signal cable to the analog RGB input terminal of the display, and the analog RGB output terminal of the computer.

• Paying attention to connector direction, firmly insert the signal
cable to terminal, and then tighten the screws at both sides.
If connecting to a D-sub 15 pin 2 row Apple P ower Macint osh, attach a
Macintosh conversion adapter (commercially available) to the analog
signal cable.

• If the display is to be ro tated, first house the cab les with the display in the long height position, so there is sufficient length when
the display is turned.
3. Refit the cov e r.
Be careful not to pinch the cable.
• If the cover is hard to refit, do not force it. Check whether cables
are trapped.
Caution: If the display is to be rotated, first house the cable, and then
check while gently turning the display. If it cannot be turned,
rehouse the cable with sufficient slack. (If there is insufficient
cable length, rotation will be impossible. Forcing rotation may
cause cable disconnection.)
