Deactivating the Infrared Receiver on the Delta-3 and SSD-66 (cont.)
STEP THREE: Next to the microprocessor chip, there are three two-pin headers. Each Delta-
3 and SSD-66 comes from the factory with shunting plugs attached to all three two-pin
headers. These shorting plugs are easily recognizable because they slide over the two-
pin headers. They are used to connect the two pins of each header together, thus
activating the corresponding function labelled on the main printed circuit board.
STEP FOUR: To deactivate the infrared receiver on the front panel, simply remove the
shunting plug covering the "IRR" two-pin header. Note: do not remove the shunting
plugs that are covering the two-pin headers labelled "ADA RX" and "ADA TX." If
there are no shunting plugs covering these headers, make sure to put them on. The
following pictures illustrate this procedure.

STEP FIVE: If you removed any shunting plugs, make sure to put them in a safe place until
you need them. Replace the top cover and screws. It is a good idea to turn the unit
upside-down briefly to make sure that nothing was dropped inside before tightening
the screws.
