Troubleshooting
Here is some basic troubleshooting that should help you with the most common troubles. Most of the cases that require attention occur during startup (and setup) of the GSM module.
LED1:
GSM module status is reported by this LED.
ON: Normal operation, GSM successfully initialized.
Flashing slow: 1s on, 0.2s off - GSM module did not responded.
Flashing fast: 0.2s on, 0.2s off - incorrect/unrecognized GSM module response.
OFF: Failure, alarm didn’t start at all
Check that the battery is charged (for at least 1 hour), then disconnect the USB power cable, press the Standby/Reset Button, wait for about a minute and then press the Start Button. This will ensure a complete restart; if problems persist, contact support.
LED2:
LED2 indicates the status of the SIM card and GSM network registration.
ON: Normal operation. SIM functioning as expected, GSM registered.
Flashing fast: 0.2s on, 0.2s off - SIM failure. Check SIM.
Possible reasons: the SIM is incorrectly/incompletely seated, or bad.
Check for proper function of the SIM in another phone, and verify correct SIM insertion into the connector.
OFF: No GSM connection
GSM network unavailable (check signal strength in your area) or
SIM is PIN protected. Disable any PIN on the SIM.
Test the SIM on your phone to ensure it is able to register onto the GSM network.
Depending on your region and operator, there could be some additional steps required before using the SIM (i.e. activation).
LED3:
SMS status indicator
OFF: Normal
On: The last SMS attempt failed (bad number?).
Verify the numbers programmed into the alarm if this LED ever lights up.
