Installation & Accessories
Power
For your safety, we have designed the AirMap to work with several
power sources, so you can ensure continuous operation by providing
multiple emergency backups. The AirMap operates on 6 volts DC using
an external power cable with a cigarette lighter adapter.
In case your plane has no cigarette lighter, we also sell an optional re-
chargeable gel cell battery with connectors. If you do have a cigarette
lighter, this rechargeable battery can function as a backup in case your
plane's power fails. If you're interested in a rechargeable battery (or
other accessories for this product), see the ordering information inside
the back cover of this manual.
Whether your AirMap is connected to the plane's power or the optional
rechargeable battery, if either of these external power sources fails, the
unit will automatically switch to the emergency backup batteries. For
the emergency backup, the unit uses AA batteries.
WARNING!
Due to the powerful backlight and the vivid color screen, sustained
use of the AirMap 2000 requires more power than AA batteries alone
can supply. Although the unit won't operate long on battery power, we
strongly recommend that you keep fresh batteries in the unit as an
emergency backup power source. If the primary power source fails,
the unit will automatically switch to the batteries, thus keeping the
unit on without interruption.
Flash memory and an internal lithium battery will keep your stored
data safe and accessible for the life of the product.
Emergency Backup Batteries
The unit requires four 1.5-volt AA batteries. We recommend that you
use alkaline batteries for the best trade-off between battery life and
cost. We recommend DURACELL

brand, but other brands will work.
If you're looking for an extended-life battery, the Duracell

ULTRA bat-
tery has performed well in our tests.
You can also use rechargeable AA alkaline batteries, such as those
made by RAYOVAC

, or rechargeable AA nickel metal hydride (NiMH)
batteries. We do not recommend nickel cadmium (NiCd) rechargeable
batteries because you will get poor battery life.
