7. Measuring

Note
Check before each use that the lens is intact. If it is damaged, contact
your retailer or the service address.
Bear in mind that the ear thermometer needs to have been in the room
in which the measurement is taken for at least 30 minutes before use.
WARNING
• Some people produce different readings in their left and right ear.
In order to record temperature changes, always measure a person's
temperature in the same ear.
• The ear thermometer may be used by children only under adult su-
pervision. Measurement is usually possible over the age of 6 months.
In infants under 6 months, the ear canal is still very narrow so the
temperature of the eardrum often cannot be recorded and the result
displayed is often too low.
• The measurement must not be taken in an ear affected by inflammatory
diseases (e.g. discharging pus or secretion), after possible ear injuries
(e.g. eardrum damage) or in the healing period after operative proce-
dures. In all of these cases, please consult your doctor.
• Use of the thermometer on different persons can be inappropriate in
the event of certain acute infectious diseases because of the possible
spread of germs despite cleaning and disinfection. If you have any
doubts, please consult your doctor.
• This ear thermometer may only be used with the protective cap in place.
• If you have been lying on one ear for some time, the temperature is
slightly raised. Wait a little while or measure in the other ear.
• As ear wax can affect the measurement, you should clean the ear
before measuring if necessary.
