1.1.12 Status LEDS
Three LED indicators provide information on GSM/GPRS Network
status, GPS data-quality and on General unit’s Status. Each LED
normally indicates unit’s status except when in Auto-OFF mode: Af-
ter one minute of a button press, magnetic switch change, or charger
connection/disconnection event all LEDs go OFF and

LED
starts blinking very shortly every 5 seconds. This is an energy saving
state where LED indicators do not reflect status of the unit. To make
all three LEDs show unit’s status again press the button once.
A single-button press on the Auto-OFF state will only make the
unit enable LED indicators so that state of the unit can be known.
Hence, a button-pressed event is not generated by this button
press. Only button presses done out of LEDS-Auto-OFF state
are considered a button-press event.
Note:
This feature is controlled by a configuration command that can be set
to instruct the unit to never use LEDs-Auto-OFF mode. The default
state is to use LEDs-Auto-OFF mode.
