Remote constantly disconnecting DOS2

[polrbt]

Hello guys,
I am still using my old volume remote on my "glossy" gold Devialet.
Since a few weeks, I cannot pair the remote to the Devialet. I can see a fast blue blinking light when I touch de remote and then a slow blinking light when I turn upside down the remote near the Devialet, but without any consequences.

Does anyone has a solution for me ?
I called Devialet after sales services and they told me "buy the new one". LOL

Please help me if anyone has a solution !

Best regards,

Pol
