Initialization - Magellan NAV 5000 User Manual

The external power jack is located on the right side of the unit,
opposite the antenna. Insert the five-pin connector of the adapter into
the power jack.

INITIALIZATION

The NAV 5000 responds more quickly when used within 300 miles
(482.7 km) of its initialized position or last fix.
To initialize, you must know your location (latitude and longitude) within
300 miles (482.7 km). You should also know your altitude as accu-
rately as possible. (Note that normal tidal fluctuations do not affect this
measurement.) lt you do not know your position, call your local marine
electronics dealer, or consult an atlas or chart.
Although you can obtain a position fix without entering an initial posi-
tion, the unit obtains the first position fix more quickly if a correct initial
position was entered. lt is also possible to operate without having
entered an altitude, but this will affect the accuracy of the position
fixes, especially in 2D operation. Therefore, regardless of which mode
you plan to use, an altitude should be entered. When a 2D position fix
is obtained, the value entered will be used as the default altitude, and
will allow the unit to obtain more accurate fixes. If you will be using the
Automatic Mode, an altitude should be entered for the initial position
because the unit may use either 3D or 2D to obtain fixes.
If no altitude is entered, the unit assumes that altitude is 0.
