Use hot mode to warm up a bottle or food. Fill the water reservoir with the correct amount of water (in ml) and place the basket and bottle (incl. bottle teat excl. cap) in it. Turn the warmer on to hot mode and let the bottle warmer do its work. Depending on the amount of food, warming will take between 3 and 5 minutes. Once the bottle warmer has beeped to indicate it is ready, use a tea towel to remove the bottle from the reservoir. NB: the bottle will feel hot due to the condensation. Make sure you dry the bottle thoroughly. Bottles with a removable bottom have a rim at the bottom; make sure this is completely dry as well. Always check the temperature of the food on your wrist before feeding. The food is at the correct temperature if you cannot feel the food or if it is lukewarm when you drip it on the wrist.
