External service provider (via the Internet)
If you, as a lift company, maintenance company or operator, connect the emergency calls of
your lifts to an external service provider, then please contact them for information about the
possibilities of connecting a display.
If your service provider is not yet able to offer this service, we will be happy to help you find
an alternative service provider.
