Selecting the Right Equipment
There are a number of companies that sell quality surge suppressors such as Sutton Designs, APC, and
Panamax. When you are looking for a surge suppressor, consider these things.
z
Expect to pay at least $50 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.
Vehicle Adapter
The Vehicle Adapter is an optional device that supplies power from the vehicle battery to operate the
computer and charge the battery installed in the unit. It typically connects to the vehicle battery using the
cigarette lighter socket.
CAUTION The Vehicle Adapter is only designed for temporary use. Use the optional
Vehicle Dock
to
power and secure the GoBook XR-1 for frequent or long term vehicle installations.
To prevent possible damage to the battery, the system will not allow the battery to charge at extreme
temperatures. Be aware of the following charging characteristics, especially if the computer is left
unattended in a closed vehicle.
