How do I reinstall a Somfy Protect Keyboard that I removed from my app?

Start installing the keyboard in your Somfy Protect application.
When you arrive on the screen below:

• Remove the batteries from the keyboard and wait 5 seconds before reinserting them.
• You have 30 seconds after reinserting the batteries to hold the “Cancel” button until you hear a long beep.

The keys in the right column will flash and the installation will continue.
