Port Check menu option, verify the IR Receiver is powered-on, and send a
signal from a powered-on IR Clicker to the IR Receiver. If the IR Receiver
is connected to the COM port you selected in the Connection Menu, a
Clicker Identified message will appear in the black Port Check window. If
the Port Check window remains blank, select another COM port in the
Connection Menu and repeat the transmission check process.
Transmitter Test
As indicated in the white message box on the Port Check window, the
Port Check feature verifies that a signal from an IR Clicker is received by
the IR Receiver. Not only can you use Port Check to verify the IR Re-
ceiver COM port connection, you can also use it to test an IR Clicker.
Verify the IR Clicker does not need new batteries. (Under normal operat-
ing conditions, the LED indicator light on a powered-on IR Clicker is
bright green. Change the batteries when the LED indicator light is dim.)
Select the Port Check option and send a transmission by pointing the
tapered end of the powered-on IR Clicker toward one of the IR Receivers
in the room and pressing a numbered button. If nothing shows up in the
Port Check window, there is a problem with the IR Clicker. Try resetting
it. Straighten a paper clip and stick the end of the paper clip into the hole
on the back of the IR Clicker. The hole is located to the right side, near
the battery pack. Push until you feel a slight click. Power on the IR Clicker
and rerun the Transmitter Test.
