Follow the messages below to avoid your systems from damage:
1. Keep your system away from static electricity on all occasions.
2. Prevent electric shock. Don‘t touch any components of this card when the
card is power-on. Always disconnect power when the system is not in use.
3. Disconnect power when you change any hardware devices. For instance,
when you connect a jumper or install any cards, a surge of power may
damage the electronic components or the whole system.

2-3. HOW TO SET THE JUMPERS
You can configure your board by setting the jumpers. Jumper is consists of
two or three metal pins with a plastic base mounted on the card, and by
using a small plastic "cap", Also known as the jumper cap (with a metal
contact inside), you are able to connect the pins. So you can set-up your
hardware configuration by "opening"or "closing"pins.
The jumper can be combined into sets that called jumper blocks. When the
jumpers are all in the block, you have to put them together to set up the
hardware configuration. The figure below shows how this looks like.
JUMPERS AND CAPS
If a jumper has three pins (for example, labelled PIN1, PIN2, and PIN3),
You can connect PIN1 & PIN2 to create one setting and shorting. You can
either connect PIN2 & PIN3 to create another setting. The same jumper
diagrams are applied all through this manual. The figure below shows what
the manual diagram looks like and what they represent.
