Indication is configurable in User Interface tab of configurator or via SMS/GPRS parameter ID.
Each 100 ms device checks if any indication is enabled in response to triggered scenarios. If two
scenarios need to indicate on the same indication source (LED or Vibration) then the active
indicating scenario needs to be finished first (with exception of Alarm and Device Off scenarios,
which can override the control of indication sources). Period setting is indicative of Periodic
scenarios and if Period is set to 0 the indication will take place immediately. When indication is
periodic and On parameter value is set to 0, the indication source will stay on until the scenario is
finished. Triggered scenarios will turn on LED and/or Vibration for a configured On duration and
then keep them off for a configured Off period of time. In case the configured Repeat value is higher
than 0 the device continues a periodic on/off cycle. Enable In Sleep parameter will let the
indication work while device is sleeping.
