2.5 Signal Acquisition Time
The first time you use your Magellan Maestro 4000/4040/4050, or if you
travel over 500 miles with it off, there may be a delay in receiving the initial
satellite fix; depending on your position and the position of the satellites,
this could take 15 minutes or more. Normal usage will receive the satellite
fix much faster, but still may take several minutes. It is important to have
your antenna rotated upward and an unobstructed view of the sky to receive
the best possible satellite signal.

2.6 GPS Maps and Your Safety
Remember, your GPS device is an aid to navigation. It must be used with
common sense, and it is important that users interpret GPS map data with a
critical eye. Landscapes and roads change or may be impassable, trees and
tall buildings can obscure GPS signals, and your GPS device may not
always reflect the complete picture. When using GPS, you must combine the
information provided by your GPS map with your relevant local knowledge,
road signage, buoys, depth soundings and changing local conditions to
generate a complete understanding of your situation.
It is your responsibility to ensure compliance to all traffic laws, including
pedestrian observance of crosswalks, and to use good judgment while
operating the Magellan GPS receiver. Safety must be your primary concern.
The Magellan GPS receiver must not be used while engaged in any activity
requiring the user's full attention to the environment. For instance, the
Magellan Maestro 4000/4040/4050 GPS receiver should be operated only by
vehicle passengers or by the driver when the vehicle has come to a complete
stop. The driver must not attempt to view the display while driving.
Disregard any unsafe, hazardous or illegal route suggestions.
Magellan maps do not include, analyze, process, consider or reflect any of
the following: legal restrictions (such as weight, height, width, load and
speed restrictions); road slope or grade; bridge height, width, weight or other
limits; population density; neighborhood quality or safety; availability or
proximity of law enforcement, emergency rescue, medical or other
assistance; construction work zones or hazards; road, sidewalk, or waterway
closures or conditions; weather conditions; pavement characteristics or
conditions; special events; traffic congestion; time of day.
