Setting Up an Infrared Transmission For information about using infrared software, refer to your operating system documentation. To set up infrared devices for optimal transmission: I Enable the infrared port on the external device as instructed in the documentation included with the device. (In Windows XP Professional and Windows 2000 Professional, the infrared port on the computer is fully enabled whenever the computer is on.) I Position the devices so their infrared ports face each other at a distance no greater than 3.3 feet (1 meter). I Position the ports so they face each other directly. Because the maximum capture angle is 30 degrees, the ports must be aligned no more than 15 degrees off center. I Shield the ports from direct sunlight, flashing incandescent light, and energy-saving fluorescent light. I Be sure no signals from remote control or other wireless devices, such as headphones or audio devices, aim at a port. I During the transmission, do not move either device and do not allow objects or movement to disrupt the beam. 7-8 Hardware Guide
