2. LCD Monitor Description
The LCD MONITOR will contain a main board, a power board, an audio board and a key board which house the flat
panel control logic, brightness control logic and DDC.
The power board will provide AC to DC Inverter voltage to drive the backlight of panel and the main board chips each
voltage.

5. Menu / Enter
•Power Button / Power Indicator: Press this button to turn the monitor ON or OFF.
Green — Power On mode. Orange — Off mode.
•MENU / ENTER : Activate OSD menu when OSD is OFF or activate/de-activate adjustment function when
OSD is ON or Exit OSD menu when in Volume Adjust OSD status.
•> / Contrast :This button will activate the Contrast control when the OSD is OFF or navigate through adjustment
icons when OSD is ON or adjust a function when function is activated.
•< / Brightness: This button will activate the Brightness control when the OSD is OFF or navigate through
adjustment icons when OSD is ON or adjust a function when function is activated.
•Auto Config / Exit:
1. When OSD menu is in active status, this button will act as EXIT-KEY (EXIT OSD menu).
2. When OSD menu is in off status, press this button for 2 seconds to activate the Auto Adjustment function.
The Auto Adjustment function is used to set the HPos, VPos, Clock and Focus.
NOTES:
• Do not install the monitor in a location near heat sources such as radiators or air dusts, or in a place subject to direct
sunlight, or excessive dust or mechanical vibration or shock.
• Save the original shipping box 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 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).
