How to use

Turn off power to the doorbell circuit before installation. Mount the cup-shaped chime housing on a suitable flat surface at the chosen location using screws and wall plugs appropriate for the substrate. Connect the unit to an 8V low-voltage supply or existing 8V doorbell wiring, observing correct polarity if indicated.
