Iridium will be changing the system time on its satellites on March 3rd, 2015. Iridium calls this "re-epoching." After that point, Iridium handsets (like the Iridium Extreme, Iridium 9555, Iridium 9505a, Iridium 9505, and the Iridium 9500) will display the incorrect system time until users enter in a string of numbers. 

You can reset the system time on your satellite phone to reflect the correct time by entering a quick string of numbers into your handset. 

• If you are reading this and it is not yet March 3rd, 2015, don't do anything to your handset. You won't see an incorrect time until after March 3rd. 
• If you are reading this and it is already past March 3rd, 2015, please follow the instructions below. 

Note: There will be no impact to handset functionality other than system time display.
