Chapter 4. Troubleshooting
If you are having problems with your M2, 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 batteries are inserted properly and are new.
Try adjusting the contrast 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 M2 is present in the Human Interface Devices
section of 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 M2. 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.
IR CODE PROBLEMS
If you are using an IR repeater system, make sure it is working
correctly with the original OEM remote. If not, you will need to
troubleshoot the IR repeater system.
