No Touch Thermometer
Dear user,
®
Thank you for purchasing the No Touch Thermometer . This thermometer was
designed by an experienced group of engineers and was produced in conformance
to all the requirements of international standard of ISO 13485:2003 (Medical devices -
Quality management systems) and FDA ASTM standards. The thermometer measures
the infrared heat emitted from the forehead surface and converts these measurements
into an oral equivalent temperature and shows a very stable and reliable reading.
Characteristics
Body Temperature
Like blood pressure, body temperature is a fluctuating range, not a stable value.
Every person has their own individual body temperature range, which can fluctuate
during the course of the day from 35.5°C to 37.8°C. Body temperature can vary
according to age, gender, time of day, activity and emotion. For example, a child’s
body temperature is usually 0.5°C higher than an adult’s body temperature. In order
to understand you and your family’s normal body temperature range, measure the
temperature at different times of day over 3 to 4 days when your general health is
stable and there is no fever. Record the results for future comparisons in case of
fever.

How to take a Measuremant
How to Obtain Maximum Accuracy
- 4 -
• Use the thermometer indoors only.
• Prior to use, the thermometer must be in the room (measurement site), not in a draw
or cupboard, for 20 - 25 minutes to become conditioned to the room temperature.
Failure to do so may cause inaccuracy.
• The person whose temperature is being taken should be in the same indoor
environment (room temperature) as the thermometer for at least 5 minutes prior to
measurement being taken.
• Temples and forehead must be cleaned from make-up and sweat a few minutes
prior to measurement.
• Avoid taking measurement for 30 minutes after physical exercise, bathing or eating.
• For repeated measurements on the same person, allow the thermometer to switch
off and wait 2 minutes before scanning again.
• Always scan the same temple when repeating and comparing measurements on the
same person.
®
• Never compare measurements using the No Touch Thermometer and other
methods of thermometry, such as Axillary (underarm), Oral, Rectal or Tympanic
(Ear). Temperature ranges vary between each method of thermometry. Therefore,
it is incorrect to compare temperature readings, of the same person, using different
methods of thermometry.
1) The thermometer must be set in an environment where the reading is to be taken
20-25 minutes before taking the reading. The person who will be taking the
reading must also be in the room for at least 5 minutes.
2) Clean all sweat, make-up etc from the forehead and wait a few minutes before
taking the reading
3) Open the thermometer by turning the Protective Cover Switch (fig.1-no.4). The
thermometer turns on automatically. A blue ray appears which helps ensure
correct positioning of the probe when taking the measurement. In fact, this ray
indicates the exact point where the reading will be taken. Wait until the “READY”
message appears before taking the reading.
Note: Correct measurement can be taken at any distance up to 10 cm.
While scanning, the thermometer emits short beeps to indicate the temperature
measurement is in progress.
- 5 -
4) Position the thermometer ’s detector (fig.1-no.1) at a distance of not more than 10
cm (4 inch) and not less than 0.5 cm (0.2 inch) from the forehead. Press the
‘‘Measurement’’ button (fig.1-no.5) and explore the entire temple area. The best
position is above the left side of the left eyebrow or above the right side of the
right eyebrow, just under the hairline.
5) 4 sharp beeps indicate that measurement is completed. At this point you can read
the temperature on the display.
6) The thermometer turns off automatically 1 minute after the measurement has
been completed. To turn off the blue positioning ray, turn the Protective Cover
Switch (fig.1-no.4). Ensure this step is carried out to avoid draining the battery
and damage to the sensor when thermometer is not in use.
Important: For repeated measurements, always position the thermometer at the
same point on the forehead.
Important Notes
- 6 -
• It is dangerous for patients to perform self-evaluation and self-treatment based on
measuring results. Be sure to consult with and follow doctor’s instructions. A selfevaluation may cause deterioration of illness.
• Affer physical exercise, bathing or eating, wait 30 minutes before taking a
temperature reading.
• For greater accuracy wait at least 2 minutes between readings.
• When pointed toward a hot object, the thermometer detects the temperature
remotely. To prevent incorrect readings, position the thermometer as soon as the
“READY” message appears.
• Avoid direct sunlight, other sources of heat and direct air conditioning as they can
affect the forehead during the temperature reading, modifying the result.
• If the light ray is no longer visible, replace the 2 x AAA batteries.
• Never expose the thermometer to extreme temperatures, dust or abrupt
movements.
• Never let the thermometer get wet.
• Never use the thermometer on irritated skin or when the forehead presents other
problems.
• Never use the thermometer when the forehead is particularly sweaty, the reading
will not be reliable.
Pressing and releasing the “Memory” button again will call up the second to last
measurement taken. You can read all the values saved by continuing to press the
memory button.
To delete the memory, press the buttons “Memory” and “Measurement” simultaneously.
This will turn off the thermometer and reset the memories.
®
The No Touch Thermometer is powered by a 3V lithium battery (it also has two 1.5V
AAA batteries to power the light ray). The lithium battery can handle approximately
12,000 measurements. If the symbol appears on the display or if the
thermometer does not completely function, remove the battery as indicated below:
• remove the lid from the battery compartment;
• remove the old battery by gently pressing back the battery holder clip;
• insert the new battery with the positive side (+) facing up and the negative side (-)
facing down;
• replace the battery compartment lid.
Memory Function
The memory function records 8 readings and remembers them for 64 hours. The last
reading performed before the thermometer is turned off is recorded to memory. To use
the memory function, turn the Protective Cover Switch (fig.1 - no. 4), press the
“Memory” button (located under the probe, fig.1- no. 2) and release it. The display
alternates the following information four times:
• previous measurement
• how many hours ago the measurement was taken
Replacing the Battery
- 7 -
Warning: Replace only with 1.5V AAA batteries (e.g. Duracell, Energizer).
other types of batteries can cause explosions or fires.
Using
Warning: The battery can explode if handled carelessly. Never recharge, remove or
position the batteries near sources of heat higher than 100°C (212°F). Do not
incinerate. Dispose of spent batteries at an appropriate differentiated collection point.
Warning: Unauthorized product modification may result in unacceptable risk.
Maintenance
®
The No Touch Thermometer has an infrared sensor located inside the probe. To
prevent damage to the sensor, close the thermometer by turning the Protective Cover
Switch. If there is dust or water inside the probe, clean it delicately with a soft cloth
and let it dry before closing.
It is best to occasionally clean the outside of the probe (without touching the sensor)
using a 70% alcohol solution.
Switching Between °F/°C
Open the thermometer by twisting the Protective Cover Switch; turns off automatically
after 1 minute; press the “Memory” button (fig.1-no.2) to change from °C to °F
readings and vice versa.
- 8 -
Warning: Replace only with CR 2032 batteries (e.g. Energizer, Varta, Panasonic).
If there is no blue ray, replace the two AAA batteries, as indicated below:
• remove the lid from the battery compartment;
• remove the old batteries;
• insert the new batteries with the positive (+) and negative (-) sides positioned
as indicated by the symbols on the housing;
• replace the battery compartment lid.
