The Bell button (transmitter)

in to the button. Pay attention to the polarity of the inserted battery.
2. Attach the back cover that serves as a holder to a wall with two screws (not supplied). It can also be attached using
double-sided adhesive tape. Check if the set operates reliably at a chosen place before installation. It is advisable
