Users are advised to use the ear thermometer in line with the instructions for use and to always seek professional medical advice without delay. Philips advises users against relying on the ear thermometer as the sole basis for a decision to seek treatment and/or professional help. Especially when the patient is a newborn (0-3 months), small child (4-36 months) or patient of any age that may not be able to communicate or take care of themselves.
