Communicating with the Infrared Port Considerations for Communication Consider the following when communicating with the infrared port: When communicating between the infrared port and an infrared port on another computer, the infrared ports on the computers must face each other directly at a communicating distance. You need to run the same communication application on both computers to communicate between your computer and another computer device. Refer to the application manuals for more information. Run only one communication application for the infrared port at a time. The communicating distance might need to be less if: - The other system is not the same model as your computer. - There is interference from ambient light. It is recommended that you do not use infrared communication in bright sunshine. Light from a certain type of fluorescent lamps can also interfere with communication. - The infrared port is not directly facing the other communicating port. Headphones or audio-visual devices that use infrared may interfere with your communication. You might hear noise through the headphones, or the computer might not be able to communicate with other devices through the infrared port. Chapter 3. Operating Your Computer 53
