The standard IR remote keypad or the optional wired remote can be set to one of two
different protocols - "A" or "B". To hard-wire a protocol to "A" or "B" in either remote,
follow Steps 1 through 5:
Step 1
Unplug the keypad from the projector (applies to wired remote only).
Step 2
Unlatch and open the empty battery compartment on the back of the keypad as shown below.
NOTE: A wired keypad opens as shown, but a cable passes through the battery compartment
cover.
Opening the Keypad
Step 3
Find the 4 jumpers located along the latching side of the battery compartment. These jumpers set
the keypad protocol and other settings so that the keypad functions in a certain manner.
Step 4: Set the Jumpers
Set the jumpers as shown on the following page. Take care to refer to the correct part of the draw-
ing - IR or wired (optional). Use tweezers or needle-nose pliers to remove and replace each
jumper as necessary.
