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.
2.3 Jumper and Switch 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 MANO526 Series, please make sure all of the jumper and switch are
in factory default position. Below you can find a summary table of jumper, switch and onboard
default settings.
Note
Once the default jumper and switch settings need to be changed, please do it
under power-off condition.

2.3.4 Clear CMOS (SW1)
This switch 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. Press the tact switch for at least 1 second.
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.
