Initializing the GPSCOM 190 for First-Time Use
The first time you power up your new GPSCOM 190
is an important step in getting the best possible GPS per-
lormance The receiver must he given an oppoTtunify to
collect satellite almanac data and cstolilish ií5 present
position. This initialization process takes approximately
3 to 5 minutes and is only necessary for first time opera­
tion, after memory loss, or when the receiver has been
moved more than 500 miles from the last calculated posi­
tion with the power off. Once your GPSCOM 190 has
been properly initialized, you should acquire satellites
and obtain a position quickly each time you power up.
Your GPSCOM 190 is shipped in the AutoLocate
mode, which is designed to let the receiver “find itself
without using its last known position (you don’t need to
worry about what lai/lon is currently displayed on the
position page, as the unit is not using that information to
calculate your present position.)
To power up your unit for first time use:
1. Position the internal GPS antenna so it has the best pos­
sible view of the sky (the internal patch antenna is locat­
ed just above the keypad, marked by the embossed
globe.) if necessary, see Appendix A for instructions on
the installation of the GA 27 external GPS antenna.
2. Turn the unit on by rotating the volume control
clockwise.
3. Rotate the squelch control clockwise until receiver
noise disappears.
4. Remain in the same location until the GPSCOM 190 has
calculated a position (the status page will be replaced
by the position page if no other buttons have been
pressed during acquisition).
Welcome Page and Database Configuration
The welcome page will be displayed while the unit
conducts a self test. Once testing is complete, the wel­
come page will be replaced by the database page (see the
top of page 7), showing the database issue date. Updates
to the database are available from GARMIN or Jeppesen
on a subscription or one time basis.
