Title: C79DMMST CreationDate: 07/16/97 13:09:22

Danger:

Do not disassemble, incinerate, or short-circuit the rechargeable battery pack. Do not put it in trash that is disposed of in landfills. Dispose of it as required by local ordinances or regulations. In the United States, call IBM at 1-800-IBM-4333 for information on disposal.

Caution:

The fluorescent lamp in the liquid crystal display (LCD) contains mercury. Do not put it in trash that is disposed of in landfills. Dispose of it as required by local ordinances or regulations.

The LCD is made of glass, and rough handling or dropping the computer can cause the LCD to break. If the LCD breaks and the internal fluid gets into your eyes or on your hands, immediately wash the affected areas with water for at least 15 minutes; then get medical care if any symptoms are present after washing.

Laser Compliance Statement

The optional CD-ROM and DVD drives in the IBM ThinkPad 770 are laser products. The drives' classification label (shown below) are located on the top of these drives.

CLASS 1 LASER PRODUCT LASER KLASSE 1 LUOKAN 1 LASERLAITE APPAREIL A LASER DE CLASSE 1 KLASS 1 LASER APPARAT

The CD-ROM and DVD drives are certified in the U.S. to conform to the requirements of the Department of Health and Human Services 21 Code of Federal Regulations (DHHS 21 CFR) Subchapter J for Class I laser products.

In other countries, the drives are certified to conform to the requirements of EN60825.

Caution:

Do not open the CD-ROM or DVD drive; no user adjustments or serviceable parts are inside.

Use of controls, adjustments, or the performance of procedures other than those specified may result in hazardous radiation exposure.

Class I (1) laser products are not considered to be hazardous. The CD-ROM and DVD drives have an internal, Class I (1), 0.5-milliwatt, aluminum gallium-arsenide laser that operates at a wavelength of 760 to 810 nanometers. The design of the laser system and the CD-ROM and DVD drives ensure that there are no exposure to laser radiation above a Class I (1) level during normal operation, user maintenance, or servicing conditions.

Infrared

Infrared technology makes wireless communication possible between infrared-enabled devices. Your computer has two infrared ports. Each port can be aimed for point-to-point communication with a portable computer, printer, or other infrared-enabled device. Each port can communicate at a distance of up to approximately 1 m (3.3 ft.) at a rate of up to 4 megabits per second (Mbps).

Video Phone Features

The Intel Video Phone** feature lets you use your computer like a telephone. It lets you see the person you are talking to in a window after you've made a call with your computer's call center. This program also lets you send such files as documents or spreadsheets, or play games with the person you are talking to. You can use either a regular telephone line or the Internet to make calls. Regular phone lines produce better audio and video quality. However, long distance calls over the Internet might save money, since you pay only for the local call. You can use this function only in receive mode if you don't have a camera; that is, you can see your caller, but he or she can't see you. To enable send mode so that the caller can see you, you must purchase an upgrade kit from Intel. This kit comes with a camera.

System Management Features

Your computer has features that enable a network administrator to control it remotely over a network from a management console. If your computer is connected to a SelectaDock III docking station with an IBM 100/10 Ethernet PCI Adapter with Wake on LAN and an IBM Auto Wake Token Ring ISA Adapter installed, the Wake-on-LAN capability is also supported.

TrackPoint with Enhanced Controls

Your computer has an enhanced TrackPoint function that enables you to make selections merely by pressing on the TrackPoint. A new center button converts the TrackPoint into a scroll controlling device or a magnifying glass on the screen.
