3.2 SYSTEM SETTINGS

Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks.
(A jumper block is a small plastic-encased conductor [shorting plug] 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-B9622 jumper pins, and the factory-default settings.

CAUTION: Do not touch any electronic component 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 the electronic components.
