Optional Equipment and Accessories

The GoBook II computer has several equipment and accessory options to further enhance your mobile

computing experience.

CAUTION When purchasing any additional accessories, purchase only those accessories that are

approved for use with your computer. Some accessories are proprietary items and can be obtained

through your system vendor. If you use items that are not approved for use with this computer, you may

cause your computer to malfunction, or to emit or receive electromagnetic radiation in excess of local

regulations. For non-proprietary accessories such as PC Cards or printers, ensure that the accessory

functions properly in your computer before making the purchase. Your system vendor may be able to

recommend reliable brands and models.

Surge Protection

A large number of computer and high technology equipment damage is directly related to AC power and

telephone line problems. These problems can include surges, spikes, noise, interference, and weather-

related problems, which in turn can cause glitches, hang-ups, crashes, performance slow downs, and

down time with computer equipment. The market is flooded with hundreds of AC power line surge

suppressors advertising high performance surge protection; only a few of them actually provide

adequate protection.

This section provides guidelines for selecting a quality surge suppressor to be used with your GoBook

II, and it helps identify a few sources for products with acceptable performance.

Selecting the Right Surge Protection

Consider the level of quality you need when selecting a surge suppressor. This depends on factors such

as surge environment, the type of equipment to be protected, and the quality of the electrical wiring and

service.

Surge Environment

Surge environment refers to the damage potential from electrical surges in a particular geographical

area. A high quality suppressor should be used if there is frequent lightning activity in the area and the

location service is fed by overhead utility poles.

Type of Equipment to be Protected

If the computer is equipped with a modem, the modem should also be surge protected. Protecting the

power line without protecting the modem line provides only partial protection.
