Q. How do I know if my Siren Marine Unit has switched from cell to satellite via the SirenSat Off Shore antenna? ?

1. The Siren Marine main unit will switch to satellite when cell signal is lost. You will see the cell signal drop in the app and the Sat signal will be green (top of the app)
2. You will also notice that the course track history line will switch from red to yellow in the app.  This indicates that the positions have been captured using satellite communications.
