Unable to use infrared transfer between Windows CE- based devices

If you are unable to use infrared to transfer information between Windows CE-based devices, try the following.

Transfer only one file, or no more than 25 contact cards, at a time.

Position the infrared ports so that they line up and are less than 20 centimeters (8 inches) but more than 2 inches apart.

￿Make sure nothing is between the two infrared ports.

Adjust the room lighting. Some types of light interfere with infrared communication. Try moving to a different location or turning off some lights.
