2.2 SYSTEM SETTINGS

Jumper pins allow you to set specific system parameters. Set them by changing the pin location of the jumper

blocks. (A jumper block is a small plastic-encased conductor that slips over the pins.) To change a jumper

setting, remove the jumper from its current location with your fingers or small needle-nosed pliers. Place the

jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful

not to bend the pins.

We will show the locations of the AR-B1651 jumper pins, and the factory-default settings.

CAUTION: Do not touch any electronic components unless you are safely grounded. Wear a grounded wrist

strap or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can

permanently damage electronic components.
