ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

Note
To identify the first pin of a header or jumper, please refer to the following
information:
Usually, there is a thick line or a triangle near the header or jumper pin 1.
Square pad, which you can find on the back of the motherboard, is usually
used for pin 1.
2.3 Jumper Settings
Jumper is a small component consisting of jumper clip and jumper pins. Install jumper clip on 2
jumper pins to close. And remove jumper clip from 2 jumper pins to open. The following
illustration shows how to set up jumper.
Before applying power to MANO842 Series, please make sure all of the jumpers are in factory
default position. Below you can find a summary table of all jumpers and onboard default
settings.
Note
Once the default jumper setting needs to be changed, please do it under power-off
condition.

2.3.1 Clear CMOS Select (JP1)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, time, and system setup parameters by erasing the
CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS,
which includes system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper clip from pins 1-2 (default) to pins 2-3. Keep the clip on pins 2-3
for about 5~10 seconds, then move the clip back to pins 1-2.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter
data.
2.3.2 LVDS VDD Select (JP2)
This motherboard supports voltage selection for flat panel displays. Use this 3x2-pin
p=2.54mm jumper to set up VDD power of the LVDS connector. To prevent hardware
damage, before connecting please make sure that the input voltage of LVDS panel is
correct.
