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.
Quality of Electrical Wiring and Service
Wiring should be up to current local 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 your
system reference the same AC ground.
Selecting the Right Equipment
There are a number of companies that sell quality surge suppressors. When looking for a surge suppressor, consider
these things.
z
Expect to pay more for a good quality surge suppressor
z
The surge suppressor should be a UL 1449, 497, and 1283 listed for surge suppression, modem surge
protection, and RFI/EMI noise filtering respectively
z
The surge suppressor should have diagnostic LEDs that verify good AC ground, proper wiring, and proper
surge operation. On/off switches that light are not recommended since they can produce electrical noise
z
The Joule ratings should be a minimum of 480 Joules for the AC surge circuit
z
The Joule ratings should be a minimum of 240 Joules for the modem
z
The modem surge circuit should present low capacitance to the modem line or it will slow the transmission
rate. Capacitance should be specified at less than 50 picofarads
z
Quality surge suppressor manufacturers generally offer a lifetime warranty
z
Consider obtaining a protected equipment coverage policy which insures the equipment in the event of surge
damage
z
The devices that will be attached to the computer also need to be surge protected
Memory Upgrade
Adding memory allows the computer to operate faster, handle more tasks simultaneously, and work more smoothly
with large files. Users who increase memory demands - by adding additional programs, for example - may notice a
slowdown in operating speed, and wish to increase memory. The GoBook VR-2 comes with one user accessible
memory socket supporting a 512MB to 1024MB memory module for memory upgrades. Please consult your dealer
if you need to add more memory.
