Do you have had some troubles, installing the Interphone app on your iOS device?
With the Release R142, the compatibility with iOS 10 has been improved to ensure a safer navigation and a more powerful connection.
First of all, to install the App you need to pair Interphone with iOS device.
Keeping off the intercom, press and hold the power button until the LED flashes are red and blue alternately.
Now you are ready to turn on the Bluetooth function on your device. Do you have in the list of the visible devices this voice "INTERPHONE (Tour, Sport or Urban)"?. If you see this, select it to match it and, if requested, enter the code "0000".
The dual blue flashing of the LED will indicate the correct connection with the device.
