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® Smart to the Philips Avent uGrow app
for charting and tracking purposes.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part of
the device, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
d = 1.167 ÖP
d = 1.167 ÖP 80 MHz to 2.5 GHz
d = 2.333 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.
(b) Over the frequency range 150 kHz to 80 MHz,
field strengths should be less than 3V/m.
Recommended separation distances

communications equipment and the ME
equipment or ME system – for ME
equipment and ME systems that are not
life supporting
Recommended separation distances between
portable and mobile RF communications
equipment and the device.
The device is intended for use in an
electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the
user of the device can help prevent
