Hygienic lens filters (LF40/LF20)
Use a clean hygienic lens lter with each measurement:
1. To ensure hygienic use
2. To protect your child from cross-contamination
3. To ensure earwax residues do not impact accuracy
of the reading
Earwax and dirt on the tip of the hygienic lens lter, even a
microscopic layer, can create an obstacle between the sensor and
the infrared heat emitted by the ear and impact the accuracy
of the measurement.
Temperature taking hints
• Replace the hygienic lens lter with every use to maintain
hygiene and accuracy.
• A measurement taken in the right ear may dier from the
measurement taken in the left ear. Therefore, always take the
temperature in the same ear.
• The ear must be free from obstructions or excess earwax
build-up to take an accurate reading.
• External factors may inuence ear temperatures, including
when an individual has:
– been lying on one ear or the other
– had their ears covered
– been exposed to very hot or very cold temperatures
– been recently swimming or bathing, or
– been wearing hearing aids or headphones for an extended
period of time
In these cases, remove the individual from the situation and wait
20 minutes prior to taking a temperature.
