▶ This device may be used by children from 8
years of age and by persons with reduced
physical, sensory or mental capacities, or a lack
of experience and knowledge provided these
persons are supervised or have been instructed
in the safe use of the device, and understand the
corresponding risks.
▶ When remotely or automatically controlling a
device, it is not always possible to guarantee
that commands are actually executed or that the
correct device status is displayed in the app and

on other Smart Home display devices because of
external circumstances. This may lead to material
damage and/or personal injury. Therefore, you
must ensure to the greatest extent possible that
no person is endangered at the time of remote
operation 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.
▶ Do not open up the device. It does not contain
any parts to be maintained by the user. If a fault
occurs, have the device checked by a specialist.
▶ We accept no liability for material damage or
personal injury which is caused by improper use or
failure to observe the safety instructions. In these
cases, any guarantee claim becomes void! We
accept no liability for consequential damage.
▶ For safety and approval reasons (CE/UKCA), the
device may not be modified and/or no changes
may be made to the device without authorisation.
▶ Any use other than that which is described in the
user manual is considered improper and leads to
the exclusion of guarantee and liability.
▶ Do not use the device if it has damage visible from
the outside, for example, to the housing, control
elements or connection sockets, or if it has a
malfunction. If in doubt, please contact our service
team.
▶ Only operate the device indoors and do not expose
it to moisture, vibrations, constant sunlight or
other sources of heat, extreme cold temperatures
and mechanical stress.
▶ Only use the device together with original
components and recommended products from
Bosch partners.

Notes
▶ The range within buildings can differ significantly
from the range in open spaces. In addition to the
transmitting power and the receiving properties
of the receiver, environmental factors such as
humidity, as well as the local structural situation,
play an important role.
▶ The device is only suitable for use in residential
environments.
▶ The device is only intended for private use.
