Echo Quick Start Guide
If the LED next to the Battery button is a solid Green, then the Echo has sufficient battery
for use. When the battery is low the LED will flash every 5 seconds, indicating power is at
50%. The LED will flash every 2 seconds when the battery is at 10%.The Echo unit, at full
charge, will have a battery life of 8 days at a 15 minute reporting rate.
If the LED next to SAT is steady, then the Echo has a connection with the Iridium satellite
network. If it is flashing, then it is attempting to gain a connection. If the LED is yellow, this
would indicate a weak connection. If the LED is not lighting up at all, then this would
indicate that there is no satellite connection currently.
If the LED next to GPS is steady, then the Echo has a connection with the GPS network. If it
is flashing, then it is attempting to gain a connection. If the LED is yellow, this would indicate
a weak connection. If the LED is not lighting up at all, then this would indicate that there is
no GPS connection currently. When testing a satellite unit, there must be a clear line of
sight to the sky at all times.
It is recommended that the Echo unit is tested every month to ensure that it is getting a steady
Iridium and GPS fix. This will be indicated by the LEDs next to SAT and GPS holding a steady
green light.
