GPS Information Page

The GPS Information Page displays your speed, elevation, the estimated accuracy,

receiver status, satellite locations, satellite signal strength, the date, time and the GPS
receiver’s current location.

Speed, Elevation and Estimated Accuracy

When the GPS is receiving at least three satellite signals, it will provide you with the

current GPS Speed and the estimated Accuracy of the GPS Location. The GPS must be
receiving at least four satellite signals to report the Elevation.

Current GPS Receiver Status

The current status of the GPS receiver will always be displayed.

Autolocate —

Forces the receiver to search for each satellite individually.

Acquiring Satellites —

The receiver will be in this mode when the unit is turned on.

The receiver will remain in this mode until it has acquired at least 3 satellite signals.

2D GPS Location —

Indicates that the receiver is only using three satellite signals. When

a 2D GPS Location is achieved, the GPS will display your current position but is inca-
pable of providing an altitude reading.

3D GPS Location —

Indicates the receiver is currently using at least four satellite signals

and is capable of providing your current position and altitude.

2D Differential Location —

Indicates the receiver is using DGPS or WAAS differential

data on three satellites. A “D” will be displayed in or above the indicator bar for each
differentially corrected satellite.

3D Differential Location —

Indicates the receiver is using DGPS or WAAS differential

data on at least four satellites. A “D” will be displayed in or above the indicator bar for
each differentially corrected satellite.

Lost Satellite Reception —
