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.
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.
