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 
XR-1, 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 
p
ower line without protecting the modem line provides only partial protection. 
Quality of Electrical Wiring and Service 
Wiring should be up to current NEC standards and have verified good AC grounds. It is important that 
your computer system be plugged into a grounded AC outlet when charging and that all peripherals 
connected to
