• The device works on the principle of electromagnetic induction. This means that when you press the button, kinetic energy is produced, when passing through a special mechanism converted to electric. To use the call, you do not need wiring or any additional batteries. Turn on and use!
• The device has 5 levels of sound volume, as well as 36 melodies to choose from. You can select the sounds you like so that unexpected calls do not make you surprise.
• When installing the device, instant synchronization is made between the receiver and the transmitter without the need for additional manipulation.
• For each of the receivers you can set up an individual ringtone, so in each room when calling there will be a specific sound.
• The doorbell is equipped with a “memory” function, which allows the gadget to remember the set melody and volume level even with sudden power outage
