NOTES
•Do not install the monitor in a location near heat sources such as radiators or air ducts, or in a place subject to direct
sunlight, or excessive dust or mechanical vibration or shock.
•Save the original shipping carton and packing materials, as they will come in handy if you ever have to ship your
monitor.
•For maximum protection, repackage your monitor as it was originally packed at the factory.
•To maintain the cleanness of your LCD display, wipe it periodically with clean and soft cloth. The screen may be
damaged by any liquid splash.
•To keep the monitor looking new, periodically clean it with a soft cloth. Stubborn stains may be removed with a cloth
lightly dampened with a mild detergent solution. Never use strong solvents such as thinner, benzene, or abrasive
cleaners, since these will damage the cabinet. As a safety precaution, always unplug the monitor before cleaning it.

D704(SSM12L) Vf=0.38V and If=1A.
So when system power on, the
system loading is about 400mA
(3.3V is about 200mA and 1.8V is
about 200mA), So D35 changed
from 1N4148(or BAT42) to
SSM12L(schottky diode).
