Installing or removing jumpers: A jumper is a small plastic encased conductor that slips
over two jumper pins. Some jumpers have a small tab on top that you can grip with your
fingertips or with a pair of fine needle nosed pliers. If your jumpers do not have such a
tab, take care when using needle nosed pliers to remove or install a jumper; grip the
narrow sides of the jumper with the pliers, never the wide sides. Gripping the wide sides
can damage the contacts inside the jumper, causing intermittent problems with the
function controlled by that jumper. Take care to grip with, but not squeeze, the pliers or
other tool you use to remove a jumper, or you may bend or break the pins on the board.
