or automated control. Please take special
care when setting up or adjusting the remote
control or when using the automated control
and check the desired functionality at regular
intervals.

any parts to be maintained by the user. If a
fault occurs, have the device checked by a
specialist.

instructions. In these cases, any guarantee
claim becomes void! We accept no liability for
consequential damage.
