This is UK , we don't read anything , especially manuals until we desperate

This is the second bell? Or all wired up inside the control panel with both cables I never had an issue the plastics on the Delta bell , unless that backplate tamper screw has snapped the tab maybe possible Or as said Bel is faulty but then I would swap the modules round if easy for you , that way you will know it's not the bell module as fault should follow Leaves you with plastics and cabling issue

External battery?

Can you post a full picture of the bell with cover off ?
