Infrared Receive
Infrared Receive or IR is used to receive files between
two IR devices. In most cases, you can also receive
files from your PC when it is equipped with an IR port.
The two devices are aimed at each other approximately
four inches apart.
If you have difficulty getting the two devices to send or
receive information, try the following:
• Transfer only one file at a time. No more than 25 contacts
should be done at once.
• Make sure that the IR port windows are clear and free of any
dirt or obstacles.
• Adjust the room lighting or move to another location. Some
types of lighting may interfere with the transmission.
