This section provides a procedure for troubleshooting the computer’s infrared (IR)
port.
Make a copy of the Diagnostics Checklist found in Chapter 5, “Getting Help,” and fill it
out as you perform the following steps:
1. Check the setting for the Infrared Port option in the Page Two menu of the
System Setup program.
For information on the System Setup program, see Appendix B, “Using the
System Setup Program.” Is the Infrared Port option set correctly for the external
device with which you are communicating?
Yes. Go to step 3.
No. Go to step 2.
2. Change the Infrared Port option to the appropriate setting, and then reboot the
computer.
Is the problem resolved?
Yes. The problem is resolved.
No. Go to step 3.
3. Insert the System Software CD into the CD-ROM drive, reboot the computer, and
run the Serial Ports device group in the Dell Diagnostics. (See “Running the Dell
Diagnostics” found later in this chapter.) The Serial/Infrared Ports device group
checks the basic functions of the computer’s infrared logic.
4. Do the tests complete successfully?
Yes. The infrared port is functioning properly. There may be a problem with
the infrared application program or with the external device. Check the
documentation that came with the application program and with the external
device.
No. Call Dell for technical assistance. (See Chapter 5, “Getting Help,” for
instructions.)
