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.

Set the jumpers as shown in Figure 2.31. Take care to refer to the correct part of the
drawing — IR or wired (optional). Use tweezers or needle-nose pliers to remove and
replace each jumper as necessary.
