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.

2.4.1 LVDS Voltage Selection (JP1)
The board supports voltage selection for flat panel displays. Use this jumper to set LVDS
connector (CN16) pin 1~6 VCCM to +3.3V, +5V or +12V. To prevent hardware damage,
before connecting please make sure that the input voltage of flat panel is correct.
2.4.2 Restore BIOS Optimal Defaults (JP2)
Put jumper clip to pin 2-3 for a few seconds then move it back to pin 1-2. Doing this
procedure can restore BIOS optimal defaults. Use SPI select to determine which BIOS
to restore; BIOS on COM ExpressTM module or BIOS on baseboard (see section 2.4.3).
2.4.3 Boot BIOS Selection (JP5)
Use JP5 to select system to boot from module BIOS or baseboard BIOS.
2.4.4 Auto Power On (JP6)
If JP6 is enabled for power input, the system will be automatically power on without
pressing soft power button. If JP6 is disabled for power input, it is necessary to manually
press soft power button to power on the system.
