Infrared Port The infrared IrDA port allows for wireless data transfer between your notebook and other IrDAcompatible devices, such as another computer or a printer, without the use of a cable. (See figure 3 on page 15 for location) It is important to keep in mind that while carrying out IR communication, both devices must be placed so their infrared ports are directly facing each other without obstruction. The devices must be separated by at least 6" but no more than 36" for maximum performance. The following conditions may interfere with infrared communications: • A television, radio remote control unit, or a wireless headphone is being used nearby. • Direct sunlight, fluorescent light, or incandescent light shines directly on the port. • DO NOT MOVE EITHER DEVICE WHILE COMMUNICATION IS ACTIVE AS IT MAY INTERRUPT DATA TRANSMISSION. • BE CAREFUL NOT TO SCRATCH THE INFRARED PORT LENS. DIRT, SCRATCHES, OR OTHER SURFACE MARKS CAN DEGRADE OPERATION. 89 - Device Ports
