Resetting the thermometer
If you press the °C/°F selection button on the side
of the thermometer for longer than 10 seconds, all
measurements are deleted from the device and all
settings return to the factory values.
Measuring temperature
Tips for proper measurement
External factors can influence your body
temperature. In the following cases, wait at
least
30 minutes before taking your temperature:
- When you have been lying on your ear
- When you had your ears covered
- When you have been exposed to very low or
very high temperatures
- When you have been swimming or bathing
- If you wear earplugs or hearing aids, remove
them first
We do not advise you to
use the device in the
following circumstances as this may cause
inaccurate measurements:
- When the temperature of the storage area
differs from the temperature of the measuring
area. In this case, wait at least
30 minutes
before you use the device.
- If you are using ear drops or other ear
medication. In this case, measure the
temperature in the untreated ear (if any).
Body temperature
Normal body temperature is a range. A person's
normal
temperature range tends to decrease with
age. The following table shows normal
temperature ranges by age.
The range of normal body temperature varies from
person to person and can be influenced by many
factors such as time of day, level of activity and
emotions.

Performing a measurement
Note: Before measuring, make sure that the probe
tip of the device
is clean.
1 Remove the protection cap before you use the
device (Fig. 6).
2 Press the power button to switch on the device.
-
The display shows the last measurement
result
as well as the history icon.
3 Hold the outer ear and gently pull it towards the
rear of the head to straighten the ear canal.
-
Children under the age of 1: hold the outer
ear and gently pull it straight back. (Fig. 7)
-
Children aged 1 year or older: hold the outer
ear and gently pull the ear up and back (Fig.
8).
4 Insert the probe tip
very gently and slowly into
the ear canal (Fig. 9).
-
Make sure the probe
tip points straight
towards the eardrum when you hold it (Fig.
10).
-
Always insert the probe tip into the same
ear, in the same direction and at the
same
depth.
Note: When you do not point the probe tip
towards the eardrum (Fig. 11), the measurement
result will be inaccurate.
Note: A temperature measurement taken in the
right ear may differ from a measurement taken
in the left ear.
5 Press the power button to start the
measurement. (Fig. 12)
-
When the measurement is done, you hear 2
beeps.
6 Remove the probe tip
from the ear canal (Fig.
13).
-
The display shows the measured
temperature. The temperature light ring
around the power button may light up red,
depending on the measurement result.
Note: The temperature display on the device
shows the measurement result for 30 seconds or
until you perform a new measurement.
Note: The thermometer is equipped with a thermal
sensor located in the tip of the device. Immediately
after a measurement the device needs a short time
(approx. 6 seconds) to stabilize the thermal sensor
to ensure the accuracy of the next measurement.
Within these 6 seconds a measurement cannot be
taken. The backlight of the device will switch off as
soon as the thermometer is ready to do a new
measurement. If you try to measure multiple times
within 6 seconds, the thermometer will give
audible feedback in the form of three short
sequential beeps, indicating no measurement was
done. In this case you should wait a few moments
and try again.
Temperature light ring
This device is equipped with a temperature light
ring around the power button (Fig. 14).
After the measurement, the ring may light up red,
depending on the measured temperature.
- When the temperature light ring lights up red,
the measured temperature is between 38.0°C
(100.4°F)
and 42.9°C (109.2°F)
Transmit and display personal
measurement results in the app
1 Start up the Philips Avent uGrow app, go to the
Temperature section and switch on Bluetooth
on your mobile device.
2 The Bluetooth symbol will light up on the
display of the thermometer to indicate it is
connected to your mobile device.
