Chapter 4. Troubleshooting
If you are having problems with your T3, please read these
troubleshooting tips before contacting technical support.
If you continue to have problems, see Chapter 5 for more
information on contacting RTI technical support.
DISPLAY IS DIM, BLANK OR UNREADABLE
Make sure the battery pack connector is attached properly and the
battery is charged.
Try adjusting the backlight level from the Control Panel page
(Refer to Chapter 3 for more details). By nature, the contrast of an
LCD screen changes with temperature, so if the remote is cold the
display will be dark and will return to normal as it warms.
USB COMMUNICATION PROBLEMS
Verify that your PC is running Windows ® 98SE or higher.
Verify that the T3 USB driver was installed the first time the T3
was connected to your PC.
Verify that the T3 is present in the Device Manager within the
Windows
® Control Panel.
Make sure you are using the programming cable that was
supplied by RTI and that both ends are connected securely.
Make sure the PC detects the presence of the T3. If it doesn’t,
unplug the USB cable, wait for about ten seconds, and plug it in
again.
If the download fails after some data has been transferred, try re-
sending the program.
