Garmin GPS 100 - Manual (Page 24)

Your GPS 100 will automatically update satellite orbital data as it operates.
If you have not operated your unit for a period of six months or longer, it will
search the sky to collect new orbital data. You will be informed when your
unit is searching the sky with the message “SEARCHING THE SKY”. Once
satellite orbital data is collected, it will be stored in battery backed up
memory. This means the data will not be lost when you turn your GPS 100
off.
If the GPS 100 cannot acquire enough satellites for 2D or 3D navigation, you
will be informed with the message “POOR GPS COVERAGE”. If this
situation occurs, check the installation and make sure the antenna is properly
connected and not obstructed. You may wish to repeat the initialization steps
and verify that the initial data are correct.
Where to go from here...
If you are using your GPS 100 for the first time, we encourage you to review
Chapter 4 on waypoints, Chapter 5 on navigation, and Chapter 6 on GOTO.
Additionally, you may wish to go through Chapter 11 on custom setups.
Finally, you don’t want to miss our sample trip in Chapter 15 using the built-
in simulator! This will help you quickly master the power and capability of the
GPS 100.
