Jumpers
Jumpers are small blocks on the system board with two or more pins emerging from
them. Plastic plugs containing a wire fit down over the pins, creating 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 from the elec-
trical outlet before you change a jumper setting. Otherwise, damage to
your system or unpredictable results may occur.
