Safety instructions
- Before installing or commissioning the device, please also be sure to read the complete user manual to ensure proper use and to comply with the warranty conditions.
- Keep the user manual in a safe place throughout the entire service life of the device.
- Do not charge used batteries or try to reactivate them using heat or other means. Do not short-circuit batteries. Do not expose batteries to strong sunlight. Do not throw batteries into fire! There is a risk of explosion!
- Ensure correct polarity when inserting the batteries! Only use batteries of the same type. Drained batteries must be removed from the device immediately. Remove batteries from the device if it is not used for a longer period of time. Increased risk of leakage!
- Keep small cells and batteries that could be swallowed out of the reach of children. Swallowing can result in burns, perforation of the soft tissue and death. Severe burns can occur within 2 hours after swallowing. In the event that a cell or battery is swallowed, seek medical assistance immediately.
- The device is not a toy! Do not allow children to play with it. Never leave the packaging material lying around unattended. Plastic film and small parts may pose a danger to children.
- 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.
- 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.
- We accept no liability for material damage or personal injury which is caused by improper use or by not observing the safety instructions. In these cases, any guarantee claim becomes void! We accept no liability for consequential damage.
- 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.
- 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.
- Please note that the emergency phone number in the app is not automatically called if the device detects a hazard. You must always make an emergency call if required!
- Please note that the device can only warn you via your mobile device if this is switched on and connected to the internet.
- With regard to the magnet supplied, maintain a minimum distance of 10 cm to 15 cm from a pacemaker. The magnets generate a field which can interfere with the functioning of pacemakers.
- Only use the device together with original components and recommended products from Bosch partners.
Notes
- The range within buildings can deviate greatly 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.

Environmental protection and disposal
These symbols mean that this product and the battery or batteries must be disposed of separately from general household waste. As an end user, you are obligated to dispose of the product and the battery or batteries via separated waste collection, for instance by passing it to an official collection point, in line with the relevant national regulations. Please note that used batteries and battery packs which are not enclosed within the old equipment must be separated from the equipment before returning the equipment. For information about the type and chemical system of the battery or batteries, as well as about replacing or safely removing them, please see the user manual.
By collecting waste separately, you are making a valuable contribution to protecting the environment and human health. This is because, by treating old equipment properly, on one hand, the potentially negative effects associated with the presence of hazardous substances are prevented and, on the other hand, raw materials are conserved through their recovery. Please also note that the avoidance of waste is an even more valuable contribution to environmental protection. Wherever possible, as well as finding a further use for the device yourself or having it repaired, passing the device to a second user is also an ecologically valuable alternative to disposal. It is also possible to return these to the place you bought the product from, provided the distributor offers a returns service voluntarily or is legally obligated to do so.
