Jumpers are small blocks on a circuit board with two or more pins emerging from them. Plastic plugs containing a wire fit down over the pins. The
wire connects the pins and creates a circuit.
To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated.
NOTICE: Make sure your system is turned off and unplugged before you change a jumper setting. Otherwise, damage to your
system or unpredictable results may occur.
