Intended use

This door intercom is a system devised for controlling access and internal communication

inside residential buildings.

Any other use is considered unintended use. The manufacturer is not deemed liable for any

damage resulting from unintended use. The risk, in this case, is assumed solely by the

installation technician.

Intended use also includes observing the manufacturer's regulations concerning use and

maintenance. The system may only be installed and serviced by persons familiar with it and

informed of the risks involved.

Cleaning

The surfaces of the TwinBus devices can become dirty due to environmental influences and

frequent use. The surfaces should only be cleaned with a damp cloth and suitable, mild

household cleaning agent.

Make certain that the plastic parts of the door station (e.g. name labels) do not come into

contact with the cleaner.

Observe the information provided by the cleaning agent manufacturer.
