● Do not touch the lens of the probe with your fingers, and do not
dissemble the device by yourself.
● Do not use the device to measure body temperature within 30 minutes
of exercising, eating or bathing.
Notice
● When the ambient temperature of a location has changed, the
thermometer should not be used for 30 minutes to ensure accurate
measurement.
● Multiple measurements should be taken over several minutes and the
average temperature of all readings noted.
● It's advisable to take readings of your temperature when you are healthy,
so you can refer to this when you have a high temperature.
● Do not measure at the sites of scars or tissue compromised by skin
disorders.
● Do not measure at the site of the forehead if the patient has trauma on
the forehead.
● Do not measure if that patient is treated with certain drug therapies.
● Do not immerse the device into water or any other liquid, and not directly
sunlight exposure.
● Do not use a mobile or cordless phone near the thermometer when
measuring temperature.
● Do not use in environments with strong electromagnetic radiation, such
as microwaves or high frequency equipment.
● Do not measure at the point of the ear when the ear has been exposed
to cold temperatures prior to measuring temperature.
● Do not use the unit to measurement ear temperature when the external
auditory canal is wet such as after swimming or a bath. It may cause
inaccurate measurements.
● Do not disassemble, repair, or modify the unit.
● This thermometer is a personal device. Do not share with others.
● The thermometer must be stored according to the technical

WHAT IS BODY TEMPERATURE?
Body temperature refers to the internal temperature of the body (core
temperature). 'Normal' body temperature fluctuates over the course of 24
hours. It tends to be lowest in the early morning and highest in the late
afternoon. Body temperature also varies depending on the part of the body
where the temperature is measured and also differs with age Hence, the
body temperature measurement obtained depends on when and where the
temperature is taken and on who the patient is.

OPERATION OF THE THERMOMETER
1. Unpack
2. Remove protective foil from the display
3. In order to ensure accurate measurement, the patient should first rest
for 30 minutes in the same room as the infrared thermometer. Do not
use immediately after exercise or bathing.

TEMPERATURE MEASUREMENT - EAR
- 09 -
@nursalonline
Press the button to turn on the unit and a
beep is heard, remove the probe cover of the
thermometer. It will switch from
forehead mode to ear mode.
For children under 1 year old, pull the ear
gently backwards.
For children over 1 year to adult, pull the ear
gently backwards and upwards.
Insert the probe into the ear canal.
Pull the ear upwards and backwards so that
the middle of the ear is clearly visible.
For the temperature to be measured
accurately in the ear canal, the tip of the
probe must be directed towards the eardrum.
If the measured temperature is higher than 38.0 °C, the device will give off
3 short beeps. The backlight of LCD will change from green to red.
•
It is advisable to take the temperature in the same ear, since the values
measured in the left and right ear may be different.
•
In the case of patients whose auditory canal is curved, the temperature
values measured may deviate owing to anatomical influences.
•
The ear should not be obstructed, for example by excessive amounts of
ear wax.
NOTE:

Press the Measurement button and wait
until you hear a short beep and a long beep,
measuring indicator light will flash. If no beep
is heard, press and release the Measurement
button button again.
As soon as you hear the long beep, remove

@nursalonline
Always check that the probe cover is fixed
onto the infrared thermometer. Prior to
measurement, the forehead should be free
of perspiration and make-up, etc.
It will automatically switch to Forehead Mode.
Press the ON button
Place the probe tip on the patient's forehead.
The recommended area is in the middle of
the forehead.
Press the measurement button and you will
hear a short beep followed by a long beep
and the indicator light will flash. Then remove
the infrared thermometer from the point of
measurement.
• The precise sensing system records the heat emitted naturally through the
skin. If the infrared thermometer is not moved over the temple, the
temperature recorded may be lower.
• It is advisable to take the temperature 2-3 times and to record the highest
value.
• In some patients the forehead temperature may differ as a result of
environmental factors and it is advisable to take and record your forehead
temperature when healthy.
• The measurement of forehead temperature is an excellent point of reference
for recognizing raised body temperature.
• If you are in any doubt about the temperature measured, please measure it
again in the ear and for the sake of accuracy, record the highest value.
NOTE:
Temperatures measured in forehead mode are displayed as comparable
rectal temperatures
