4．Connect all the signal lines, cable, panel-control circuitry and power supply；
5．Start the computer，finish BIOS setup.
Key components of this motherboard are Integrated circuit, and these components
will be easily damaged by electrostatic influence. So, before installing the motherboard,
you should always keep the following precautions in mind:
1．Hold the board by the edges; don't touch any components or pins on the board.
2．Use a anti-static wrist strap or wear anti-static gloves while getting in touch with integrated
circuit components (such as CPU, RAM).
3．Place components in a grounded anti-static bag/pad when these components are
uninstalled.
4．Please make sure the power switch is disconnected before inserting the power plug.
2.3 CPU & Memory Installation
This motherboard is equipped with 1xDDR3Lslot.Please pay attention to the following two
points when installing memory bank：
1．When fixing, make sure the notch matches SO-DIMM socket and then insert memory bank
into the socket. Press it down to tight the connection.
2．Choose the proper memory bank that supports motherboard specification。
2.4 Jumper Setting
Please setup the jumpers accordingly before installing hardware devices.
Note: How to identify jumper and PIN1 of interface
Please observe the word mark of plug socket, it will use “1”or bold line or triangular
symbols; and please look at the back of PCB,each weld spot has a squar point, that is PIN 1;
Usually there is a withe arrow beside PIN 1.
2.4.1 CMOS Content Clearance /Hold Setting（JCC）
CMOS powered by on board button battery. Clean CMOS will lead to a permanent
elimination of the previous system setting and back to the original (default setting) system
settings.
Steps :（1）Turn off the computer, disconnect the power supply ；
（2）Use jumper cap short JCC Pin 1 and Pin 2 for 5~6 sec，Then restore the default
setting of Pin2 and Pin 3.；；
