LED Indicators

LEDs indicate:
During Startup
Mode Remains off
T24 Activity Flashes when T24 data packets are received
Network Activity Remains off
T24 Error Flashes
Network Error Flashes
SIM Error Remains off
The startup mode can take up to a couple of minutes while cellular network connection is achieved.
Startup will commence after the Reset Button is pressed or power is first applied. During startup the Mode LED
will remain off.
If there is a problem with the on board T24 radio or the cellular network module then either the T24 Error LED or
the Network Error LED will remain lit while the Mode LED flashes and the module will be inoperable. Pressing
the Pair/Reset switch will reset and try the connections again.
If after applying power or pressing the Reset button the unit detects a problem with the internal real time clock
the LEDs will all go out. The unit will reset and try again a few seconds later causing all LEDS to flash on. If this
state persists you should remove the battery connector and any external power supply for a few seconds then re-
attach.
