No, you cannot permanently set the thermometer to adult, so it will automatically stay in this mode. The Braun ThermoScan 7+ ear thermometer uses Age Precision® technology, which requires manual selection of age before each measurement.

To change the age setting, you must press the Age Precision button before each measurement to cycle through the different age groups (e.g. 0-3 months, 3-36 months, 36 months+). You must select the appropriate age each time before taking a temperature measurement.

Yes, you have to press the power button and the Age precision button at the same time for 4 seconds: once the different age icons flash, you have to move to the default age of your choice with the Age precision button. The thermometer will switch off automatically and when you switch it on again it will restart in the chosen default mode.
