Status LED: when first entering Tracking Mode, the LED will not light up. This LED stays solid if
the last SBD transmission had a valid GPS fix and successfully received by the gateway, blinks if
the last SBD transmission was unsuccessfully sent or did not have a valid GPS fix but one was
sent since the unit was turned on, and stays off if no SBD transmission with a valid GPS fix was
sent to the gateway.
Emergency LED: lights up when the Emergency button is pressed or the Input S0 is activated.

Status LED: when first entering the Command mode, this LED will not light up. If the last SBD
session does not have an error the LED stays solid. An error occurs when a transmitted SBD
message is not being acknowledged by the Gateway or if a message received from the Gateway
contains an error(s). The LED blinks only after the 9602-LP is powered up with the last SBD
session having an error but the next SBD session is error-free.
For those applications where prolonging battery life is essential, the LEDs can be turned OFF using the
^LEDS AT command or using the SatTerm LED’s tab as shown in Figure 12. The 9602-LPs are shipped with
all LEDs set to on.
