Voice Mate H1 error code : 302

Can’t appairing with my system…

Have issues too with Voice Mate H1.

This foil strip that keeps the battery deactivated cannot be removed. It is too tight and I am afraid of damaging the Voice Mate H1.
How can I open the small metal plate without damaging the Voice Mate H1?
