3-8 Operating Instructions 3.6.1 Using the Fast Infrared (FIR) Port The FIR port, located on the rear of the computer, offers wireless communication with other Texas Instruments notebook computers or a variety of IRDA-compliant devices. Without a physical connection, you can print remotely, transfer files between computers, use a remote mouse during a presentation or receive information from a PDA or pocket organizer. To transfer a file follow these steps: Align the FIR ports of the two devices making sure that the distance separating them is between six inches and three feet (one meter). 3.6.2 Using Zoomed Video Features Your computer supports Zoomed Video (ZV) PC Cards through the PC Card slots. ZV PC Cards connect to the internal ZV port, allowing advanced multimedia capabilities such as video conferencing and on-screen television at full, smooth motion. The Zoomed Video port adds a dedicated video bus that provides a direct link between a PC Card and the VGA accelerator or audio DAC. This “detour” lets video and audio data bypass the PCI bus, reducing bandwidth impositions and improving system performance for more fluid audio and video. 3.6.3 MPEG PC Card The optional MPEG PC Card uses the Zoomed Video port built into the computer to display MPEG video and audio on the computer. The MPEG card features MPEG-1 video playback with 16.7 million colors, MPEG-1 audio layers I and II, is MPC3 compliant and Windows 95 Plug and Play. With this option you can run full-motion video, combined with digital audio, graphics, text and data, enabling you to create far more effective presentations or play the most advanced video games. 3.7 Battery Saving Tips There are a number of actions you can take to reduce the rate at which your computer depletes the battery. By taking some or all of these actions, you can substantially increase the time you can operate on battery power before recharging the battery: ¨Reducing screen brightness — Although the screen controller uses new technology to increase brightness without increasing energy consumption, the screen is still the largest single consumer of the battery charge. Reducing the brightness to the lowest acceptable level increases battery life. To reduce the brightness, press Fn+¯. ¨Caching the hard disk — By caching the hard disk, you can reduce the length of time the hard disk is rotating and using energy. Both Windows 95 and Windows for Workgroups use a disk-caching program by default. As long as you have not disabled these programs, you can take advantage of the battery savings.
