replace the florescent tube unit. Please
inquire at the shop where you purchased the
monitor or your nearest Sharp authorized
Service Center. (Never attempt this
replacement on your own.)

- In the initial period of use, due to the

characteristics of florescent tubes the screen
may flicker. (This is not a malfunction.)
Should this happen, check by first turning off
the power, then turning it on again.

- Recommended resolution is 1024 x 768.
- All are compliant only with non-interlaced.
- Frequencies for Power Macintosh are reference

values.

- If the monitor is receiving timing signals that are

not compatible, [OUT OF TIMING] will appear.
Follow your computer

'

s instruction manual to set

the timing so that it is compatible with the
monitor.

- If the monitor is not receiving any signal (synch

signal), [NO SIGNAL] will appear.

The monitor is based on VESA DPMS (Display
Power Management Signaling).
To activate the monitor's power management
function, both the video card and the computer
must conform to the VESA DPMS 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 DDC1 and DDC2B.

6. Attach the arm to the monitor with four screws.

Note:
- The screws used to attach the arm should be M4

screws with a length of 8 mm ~ 10 mm protruding
from the surface to be attached. Using different
screws could cause the monitor to fall off or to be
internally damaged.

7. Connect the analog signal cable, the audio

cable and the power cord.

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.

When choosing the arm to be installed please take
note of the following points.
- The arm should be compatible with the VESA

standard, and there must be a gap of 75 mm x
75 mm between the screw holes on the section
to be attached.

- The arm must not fall off or break off after being

attached to the monitor.

1. Ensure that both the monitor and computer are

switched off.

2.Unplug the power cord from the AC outlet.
3. Remove the analog signal cable and the audio

cable from the computer.

4. Press down on the stand and gently fold back the

monitor.

- Be careful not to allow your fingers to be

pinched.

- Do not overly bend the cable or add extension

cords as this could lead to malfunction.

5. Being careful not to damage the monitor, spread

out a soft cloth and lay the monitor on it display-
side down.
