GPS Sensor Mode Start-Up
When starting in GPS Sensor mode, the RAC Geo will Display GPSSen in
D-1, indicating it is set to GPS Sensor Mode. It will then switch to display
GPS FO in D-1 and SEnSor in D-2 and begin to look for GPS satellites.
The RAC Geo will display
GPS F1
in D-1 once it has found a minimum
number of satellites for a GPS signal (usually in less than 60 seconds).
Once the RAC Geo has reached an F1 lock the Geo will set itself in Count
Hold with
CH displayed in D-2 and 0 displayed in D-1. At this point, the
Geo is ready to start counting or access menu functions.

Looking for GPS Satellites
Once F1 is achieved, the Geo is ready to start, but it will continue to try to
find more satellites in the background. Also during start up, the RAC Geo
will perform some behind-the-scenes functions including: set the unit of
measuring (feet, mile, meter) and the vehicle number to be the last one used
when the RAC was turned off, set itself to count up, and set the Distance
Pulse Output interval to zero.
