Even with S/A on, and without a DGPS receiver, your Eagle Expedition
gives you outstanding position and navigation information. Most people
are amazed when they actually use a GPS receiver and see what it does.
Please sit down with the unit and this manual and familiarize yourself with
them before using the Eagle Expedition in the “real world”. A simulator is
built in, which lets you practice.
INSTALLATION
The Expedition will operate from four AA batteries, one DURACELL
®
re-
chargeable battery, or from 5 to 16 volts DC. An optional cigarette lighter
adapter is available to plug into a car or boat’s electrical system. The
Expedition automatically switches to external power when it’s plugged
into the unit. If, for any reason, the external power fails, the unit will auto-
matically switch to the batteries.
The Expedition does not require batteries when the external power is in
use, however they make a good backup in case of power failure.
BATTERY INSTALLATION
For battery operation, the Expedition requires four AA batteries or the
optional DURACELL
®
DR-121 rechargeable battery. (The DR-121 battery
comes with the Eagle
®
BR-1B recharger. This charger lets you recharge
the DR-121 battery while it’s in the unit, plus you can use the Expedition
while the battery is charging.) If you use alkaline batteries, we recom-
mend DURACELL
®
brand, but other brands will work. You can also use
rechargeable ni-cad batteries (however, they won’t last as long as stan-
dard alkalines). Rechargeable alkaline batteries such as RayOVac
®
Re-
newals
®
will also work.
Do not use heavy-duty batteries or
any battery type other than the ones
listed above. Do not mix different
types of batteries. (For example,
don’t use both alkaline and ni-cad
batteries at the same time.)
To install the batteries, first turn the
Expedition over on its back. Now
push the two tabs to the left and
raise the battery cover as shown
below. The bottom part of the case
holds the batteries.
