Congratulations on your purchase of this product.
Please read the instructions carefully before using
the thermometer for the first time and keep these
instructions in a safe place. This product is i11tended for
measurement of human body temperature.
Operating Instructions
Before using, please disinfect the probe. To switch on,
press the ON/OFF button next to the display. A short
beep will sound indicating that the thermometer runs
a self-check test during which all the digital segments
appear on the LCD. This will be folowed by the last
measured temperature. After this, the letters "Lo" and
a flashing " 0 C" or "°F" appear and the thermometer
is ready for use. If the ambient temperature is below
32°C or 89.6°F , then "Lo °C" or "Lo °F" will appear on
the LCD. If the ambient temperature is over 42.9°C
or 109.2°F; "Hi
0
( "
or "Hi °F" will appear on the LCD.
During the temperature reading, the temperature is
displayed continuously and the "
0
C"
or "°F" symbol
flashes. The measurement is completed when a
constant temperature value has been reached. The
temperature value is considered constant when the
temperature rises less than 0.1 °C within 3 seconds.
When the constant temperature value is reached, a
beep will sound 10 times "bi-bi-bi-bi-.. :; and the "°C" or
"°F" symbol will stop flashing. The highest measured
temperature appears on the LCD.
Fever alarm
If the detected body temperature exceeds 37.5°C/
99.5°F the thermometer will sound a fever alarm: "bi-
bi-bi---bi-bi-bi---.. :' .
Note: this a maximum thermometer and the displayed
temperature can increase slightly if the measurement
continues after the beeps. This is particula rly the case
with axillary measurements which require a signifi-
cantly longer measurem~nt time for accurate measu-
rements. Please follow the instructions described in
the "Methods of measuring temperature" section.
Fever indication
@
Over 37.9°C/ 100.2°F; fever!
A 37.5°C-37.9°C/ 99.5°F-100.2°F; slig htly higher

temperature.
@
<
37.4°C/ 99.5°F; good temperature.
Auto-off function
When the measu rement is completed, switch the
t hermometer off by pressing t he ON/ OFF button. If not
switched off, the thermometer wi ll sh ut off automati-
ca lly after 10 m inutes.
Memory function
When the thermometer is turned on, the last measu-
rement will show on screen for 2 seconds. Press the
button again to turn the thermometer off. When the
thermometer will remain turned on, the result will be
overwritten by the new measurement.
Methods of measuring temperature
It is important to remember that the body tempe-
rature reading depends on the position where it is
measured. For this reason, the measurement position
must always be specified in order to ensure that a
correct temperature reading is recorded.
Rectal/ Vaginal Measurement
This is the most accurate method from a medical point
of view because it is closest to the core body tempera-
ture. The thermometer tip is inserted carefully into the
rectum for a maximum of 2 cm. The usual measuring
time is approximately 8 to 15 seconds.
Axillary Measurement
Placing the thermometer in the armpit provides
a measurement of surface temperature that can
fluctuate by around 0.5°C/0.9°F to 1.5°C/2.5°F from
rectal/ vaginal temperature readings in adults. The
usual measuring time for this method is approxi-
mately 20 to 30 seconds. It should be noted that an
exact reading won't be obtained if, for example, the
armpit temperature is lower than normal (the armpit
tem perature has been cooled down). If this is the case,
extend the measuring time to 5 minutes in order to
obtain a reading that corresponds more closely to the
core body temperature.
Oral Measurement
There are different heat zones in the mouth. As a
general rule, the oral temperature is 0.3°C/0.5°F to
0.8°C/1.4°F lower than the rectal/ vaginal tempe-
rature. To ensure that the reading is as accurate as
possible, place the thermometer tip to the left or right
of the root of the tongue. The thermometer tip should
remain in constant contact with the tissue under the
tonque during the reading. The mouth should remain
closed during the reading. Eating or drinking or bre-
athing through the mouth just before measuring will
result in an inaccurate temperature reading. The usual
measuring time is approximately 8 to 15 seconds.
°C and °F switch
Turn the thermomete r off. Press and hold the On/Off
Button for 3 seconds t o switch the measuring scale.
Cleaning and disinfection
The best way to clean the thermometer tip is by
applying a disinfectant (e.g. 70% ethyl alcohol) with
a damp cloth. Th is waterproof thermometer can be
immersed in lukewarm water for thorough cleaning
and disinfection .
Safety precautions
Do not expose the thermometer to hot water
over 50°C/122°F.
Do not expose the thermometer t o high tem pe
ratu res or direct sunlight.
