Communications Setting Up an Infrared Transmission For information about using infrared software and enabling or disabling infrared ports, refer to the operating system Help files and to the documentation included with the external infrared device. To set up 2 infrared devices, such as the notebook and an optional printer, for optimal transmission: ■ Position the devices so that their infrared ports face each other at a distance of no more than 3.3 feet (1 meter). ■ Position the ports so that they face each other directly. The maximum capture angle is 30 degrees, so the ports must be aligned no more than 15 degrees off center vertically or horizontally. ■ Shield the ports from direct sunlight, flashing incandescent light, and fluorescent light. ■ Be sure that signals from a remote control or other wireless device (such as a cell phone, a headset, or an audio device) do not aim at either port. ■ During the transmission, do not move either device and do not allow objects or movement to disrupt the beam. Avoiding Standby While Using Infrared Standby is not compatible with infrared transmission. If the notebook is in Standby, an infrared transmission cannot be initiated. If Standby initiates during an infrared transmission, the transmission stops. To resume from Standby, briefly press the power button. The transmission resumes when the notebook resumes from Standby. 7-14 Startup and Reference Guide-Part 2
