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 ra
ting 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.

Intended use

The product is intended for measuring the tempera
ture of the human body via the ear canal by an in
frared 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 tempera
ture is regulated by the hypothalamus (Abb. 2).
The hypothalamus (1) shares the same blood sup
ply 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.
- Do not put the device in a wet ear canal after
swimming or bathing. This may cause injury to
the ear canal.
- Do not use the device if it is broken or dama
ged. Using a broken or damaged device may
cause injury.
Caution
- Only use the device as described in this user ma
nual. Do not use it for any other purpose.
- The device is not intended as a substitute for
consulting a doctor. Measurement results are
for reference only.
- When the device is used to measure the tempe
rature of a child, it has to be operated by an
adult.
- If you clean the ear, wait 5-10 minutes before
you use the device.
- Earwax in the ear canal may cause inaccurate
measurements. Make sure the ear canal is clean
before you use the device.
- Do not take apart, repair or change any part of
the device at any time.
- Do not store the device in extreme temperature
(below -20°C/-4°F or over 60°C/140°F) or in ex
treme levels of humidity (below 15%RH or over
85%RH). This may cause inaccurate measure
ments.
- Keep the infrared sensor dry, clean and unda
maged to ensure accurate measurements.
- Do not touch or blow at the infrared sensor. A
polluted infrared sensor may cause inaccurate
measurements.
- Never clean the device with an abrasive clea
ner, thinner, benzene or immerse the device in
water or other liquids.
- When the temperature of the storage area dif
fers from the temperature of the measuring
area, wait at least 30 minutes before you use
the device.
