The bottle warmer allows you to keep water or solid food warm using the bottle or dinner mode. Simply pour 200 ml of water into the reservoir, place the bottle or jar inside, and select the appropriate mode and temperature on the display. The warming cycle will begin automatically and shuts off after 10 hours (bottle mode) or 3 hours (dinner mode). You can stop the program at any time. For safety reasons, prolonged warming is not recommended. Please refer to the manual for detailed instructions.
