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 regulations. For non-
proprietary accessories such as PC Cards or printers, ensure
that the accessory functions properly with 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 issue that may cause
glitches, hang-ups, crashes, performance slow downs, and
computer down time. It is recommended that you use a
quality surge protector with your computer and any attached
peripherals.

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 GD8000 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.
