more set phone numbers. When the Alarm function is activated the device starts searching its location

Cycle call method
To configure this alarm method you need to create a phone number list.
No answer time - when alarm is active, device will call to the first number in the list. If this number is
busy or did not answer after this time limit is reached, device will terminate this call and start calling to
the next phone number on the list.
Conversation time and conversation overtime - if the call will be answered device starts counting
conversation time. When the conversation time reaches its limit, the device will make a warning
notification and start counting Conversation overtime. When the conversation overtime reaches its
limit, the device will terminate the conversation and start calling to the next phone number on the list.
Time for alarm stop - if the conversation time or overtime reaches or the call is ended by the caller or
recipient the device will start counting the alarm for alarm stop parameter. When it reaches, if there is
no request for call termination and alarm has not stopped, the device will start calling the next number
in the phone number list.
