Fast and contactless temperature
measurement
The innovative infrared technology ensures safe
and hygienic temperature measurement within
seconds.
Multifunctions
The extended measuring range (0 °C - 100 °C;
32 °F - 212 °F) permits the measurement of
body temperature and of the temperature of ob-
jects or surfaces, e.g. baby bottles, bath water,
ambient temperature.
Safe and hygienic
The avoidance of direct skin contact means re-
duced transmission of viruses and other germs.
Accurate and reliable
The unique measuring probe, which incorpo-
rates an advanced infrared sensor, ensures
that, when applied correctly, each measurement
is accurate and reliable.
Fever alarm indicator
10 short beeps and a red LCD backlight indi-
cated that the patient’s temperature is above
37.5 °C (99.4 °F).
Memory
The last 30 readings can be recalled from the
memory, enabling efficient tracking of tempera-
ture variations.

SAFETY PRECAUTIONS
IMPORTANT INFORMATION
ABOUT TEMPERATURE
MEASUREMENT
This thermometer measures infrared energy
radiated from the forehead as well as from ob-
jects. This energy is collected through lenses
and converted into a temperature value.
Temperature readings obtained by scanning
above the eyebrow area will provide the great-
est accuracy.

1.5 V size AAA batteries. The batteries need re-
placing when this icon “ ” is the only symbol
shown on the display.
Slide the battery cover open and insert 2 new
batteries, then close the battery cover again.
When replacing the batteries, ensure correct
polarity by referring to the symbols in the battery

NOTES:
• The thermometer and the patient must re-
main in a room with a stable room tempera-
ture for at least 30 minutes before measuring
the temperature.
• Do not take a baby’s temperature during or
directly after breastfeeding.
• Do not use the thermometer in a humid envi-
ronment.
• Use of the unit under operating conditions
outside the range indicated may result in
false readings.
• Patients should not drink, eat, or exercise be-
fore/while taking the measurement.
• Do not move the measuring device away
from the area to be measured until the termi-
nation beep has sounded.
• 10 short beeps and a red LCD backlight indi-
cate that the patient’s temperature is above
37.5 °C (99.4°F).
• Always take the temperature at the same
measuring site, otherwise the temperature
readings may vary.
• A control measurement using a conventional
thermometer is recommended in the follow-
ing cases:
1. In the case of new-born infants up to
100 days old.
2. In the case of children under three
years of age with a compromised im-
mune system, for whom the presence
or absence of fever is critical.
3. While the user is learning how to use
the thermometer, until such time as
he/she has become thoroughly familiar
with the instrument and obtains consist-
ent readings.
4. If the measurement is suspiciously low.

USE:
1. Press the ON/OFF button . The display
is activated to show all segments for 2
seconds.
2. The last measurement reading will automati-
cally be shown on the display for 2 seconds
with the “M” icon.
3. The thermometer is ready for measurement
as soon as the “°C” or “°F” icon starts flashing
and a beep sound is heard.
4. Press the mode button until you see a symbol
in the form of a head on the display. Now you
are in the body temperature measurement
mode.
5. Aim the thermometer at the centre of the fore-
head, holding it no more than 5 cm away from
the skin surface. If the forehead is covered
with hair, perspiration or dirt, please remove
this beforehand in order to ensure accurate
measurement.
6. Press the START button and steadily move
the thermometer from the middle of the fore-
head to the temple area (about 1 cm above
the eyebrow). The activated blue tracking
light will indicate the measurement area.
7. After 3 seconds a long beep will verify the
completion of measurement. If the temple
area has not been reached by the time the
long beep is heard, repeat the measurement
as described above, but move the thermom-
eter a little faster.
8. Read the recorded temperature from the LCD
display.
- If the reading is below 37.5 °C (99.4 °F), you
will hear a long beep and the backlight of the
display will be green.
- If the reading is at or above 37.5 °C (99.4 °F),
you will hear 10 short beeps, and the back-
light of the display will be red.

NOTE:
• Readings from different measuring sites
should not be compared, as normal body
temperature varies depending on the meas-
uring site and the time of day.
Normal body temperature ranges:
• In the rectum (rectal): 36.6 °C - 38.0 °C
(97.9 °F - 100.4 °F)
• In the mouth (oral): 35.5 °C - 37.5 °C
(95.9 °F - 99.5 °F)
• In the armpit (axillary): 34.7°C - 37.3°C
(94.5 °F - 99.1 °F)
• Geratherm®non contact: 35.4 °C - 37.4 °C
(95.7 - 99.3 °F)
1. Follow steps 1-3 in the chapter on Measuring
Body Temperature.
2. Press the mode button until you see a symbol
in the form of a house on the display. Now
you are in the object temperature measure-
ment mode.
3. Aim the thermometer at the centre of the ob-
ject whose temperature you wish to measure,
holding it no more than 5 cm away from the
surface. Press the START button. After 3 sec-
onds a long beep will verify the completion of
measurement.
4. Read the recorded temperature from the LCD
display.
