In the Preferences menu, make sure that the desired keypad option (Front IR,
Rear IR, or Wired Keypad) is set to Option 1 "A or B". This will ensure that the
projector will continue to respond to the keypad after you change protocol.
Unplug the keypad from the projector (applies to wired remote only).
Unlatch and open the battery compartment on the back of the keypad as shown in
Figure 2-29. Make sure the batteries are in place (IR keypad only).
NOTE: The optional wired keypad appears as shown, but there is a cable
passing through the battery compartment cover.
Figure 2-29. Opening the Keypad (shown without batteries)
Find the 4 jumpers located along the latching side of the battery compartment
(Figure 2-30). These jumpers set the keypad protocol and other parameters so
that the keypad functions in a certain manner.
