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-B1631ET 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.
