(a) Field strengths from fixed transmitters, such as
base stations for radio (cellular/cordless) tele
phones 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 mea
sures 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 between
portable and mobile RF communications equip
ment and the device.
The device is intended for use in an electromagnet
ic environment in which radiated RF disturbances
are controlled. The customer or the user of the
device can help prevent electromagnetic interfer
ence by maintaining a minimum distance between
portable and mobile RF communications equip
ment (transmittters) and the device as recommend
ed below, according to the maximum output pow
er of the communications equipment.

For transmitters rated at a maximum output power
not listed above, the recommended separation dis
tance d in metres (m) can be estimated using the
equation applicable to the frequency of the trans
mitter, where P is the maximum output power rat
ing of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1 At 80MHz and 800MHz, the separation dis
tance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situa
tions. Electromagnetic propagation is affected by
absorption and reflection from structures, objects
and people.

Introduction
Congratulations on your purchase and welcome to
Philips! To fully benefit from the support that Phi
lips offers, register your product at www.phi

Intended use
The product is intended for measuring the tempera
ture 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 ear thermometer has been developed
for accurate and fast human body temperature
measurements in the ear.
Research indicates that the ear is an ideal site for
taking the body temperature. The body temperatu
re 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 HealthSuite health
app for charting and tracking purposes.

Important safety information
Read this important information carefully before
you use the device and save it for future reference.
Warning
- Do not measure the body temperature at the
ear site if the ear is inflamed or infected.
- Keep the device out of the reach of children.
Children may not be able to use it according to
the instructions in this user manual. It is not a
toy.
- Do not throw disposable batteries into fire. Bat
teries may explode.
