LED in the unit will turn on to indicate the unit is ready for use.
System operation
A registered user can gain access by calling the unit which will automatically activate its output to
trigger the gate/door to open. If the user’s mobile number is a privet number, then he can gain access
by sending an SMS to the unit. If access by SMS is desired, then SMS: O (lowercase or uppercase) to
the unit.

The unit can be programmed by SMS commands.
