Infrared Connection Guidelines
■ Be sure the infrared ports on both devices are turned on and
facing each other at a distance no greater than 1.5 feet (about
0.5 meter).
■ Avoid moving the infrared ports away from each other during
data transmission.
■ Avoid interference from remote control units, such as
wireless headphones or audio devices, pointed at the infrared
ports.
■ Avoid direct sunlight, fluorescent light, or flashing
incandescent light close to the infrared ports.
■ Keep the path between the infrared ports free of any objects
that might interfere with data transmission.
