I'm having a problem using the IR port. What can I do?
Verify that the IR port is enabled. Enter the BIOS Setup utility and access
the Peripheral Setup menu.
Check that both the sending and receiving system and device are using the same
transmission software.
If you are transmitting underneath a fluorescent light, try repositioning the system and
device so that they are not directly under the fluorescent light.
