AVT910 B

The castle uses typing entering the code using a remote keyboard. The coupling of both cooperating parts is possible on the acoustic path. To control the lock, a DTMF code transmitter is necessary. In the past, this function was performed by the so-called "dialer", now almost every mobile phone generates the necessary signals.
In order to enter the code, the phone needs to be closer to the microphone of the lock and enter a specific sequence of numbers.
