Introduction

Congratulations on your purchase and welcome to
Philips! To fully benefit from the support that
Philips offers, register your product at
www.philips.com/welcome.

Intended use

The product is intended for measuring the
temperature of the human body via the ear canal
by an infrared sensor. The device is intended for all
ages in a home environment.

General

This Philips Avent uGrow smart ear thermometer
has been developed for accurate and fast human
body temperature measurements in the ear in the
adjusted mode.
Research indicates that the ear is an ideal site for
taking the body temperature. The body core
temperature is regulated by the hypothalamus
(Fig. 2). The hypothalamus (1) shares the same
blood supply as the tympanic membrane (2).
Measurement results can be transmitted via
Bluetooth® to the Philips Avent uGrow app for
charting and tracking purposes.

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.

Age

0-2 years 36.4 - 38.0 °C 97.5 - 100.4 °F

3-10 years 36.1 - 37.8 °C 97.0 - 100.0 °F

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.

recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
d = 1.2 ÖP
d = 1.2 ÖP 80 MHz to 800MHz
d = 2.3 ÖP 800 MHz to 2.5 GHz
where P is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey (a),
should be less than the compliance level in each
frequency range (b).
Interference may occur in the vicinity of equipment
marked with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, the higher
frequency range applies.
NOTE 2 These guidelines may not apply in all
situations. Electromagnetic propagation is affected
by absorption and reflection from structures,
objects and people.
(a) Field strengths from fixed transmitters, such as
base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field
strength in the location in which the device is used
exceeds the applicable RF compliance level
above, the device should be observed to verify
normal operation. If abnormal performance is
observed, additional measures may be necessary,
such as re-orienting or relocating the device.
