Thank you for your purchase of this thermometer. To correctly utilize all the advantages of this product, you should
familiarize yourself with these operating instructions before using the thermometer the first time. Keep these
instructions in a safe place for future reference.
SPECIAL FEATURES
• Automatic self-test: guarantees a specified measuring accuracy for each temperature reading! «ERR»‑(error) is
immediately indicated if any deviation is registered.
• Temperature measurement within 60‑90 seconds depending on measuring method used.
• Digital display for temperature changes as minor as 0.1°C / 0.1°F.
• Automatic switch off: after approx. 10 minutes – for longer battery life.
• Battery: Silver oxide high drain. (Non disposable)
IMPORTANT SAFETY INSTRUCTIONS
• The thermometer is suitable exclusively for measurement of body temperature.
• The battery cover is sonic-welded with the main housing of the thermometer; the battery is well sealed inside the
thermometer to reduce the risk of being swallowed by children.
• Protect the thermometer from hitting and striking.
• Avoid ambient temperatures above 60°C / 140°F. NEVER boil the thermometer!
• Use only the commercial disinfectants listed in the section «cleaning and disinfecting» to clean the thermometer. The
thermometer must be intact when immersed in liquid disinfectant.
• Warning: The thermometer contains a long‑life battery. For disposal, please comply with local regulations for special
waste.
• Do not use the device if you think it is damaged or if anything appears unusual.
• Ensure that children do not use this device unsupervised; some parts are small enough to be swallowed.
• The manufacturer recommends to verify the accuracy by an authorized laboratory every 2 years.
• Do not store the unit under direct sunlight, at a high temperature , or in high humidity or dust. Performance may be
degraded.
• Using the unit in the immediate vicinity of mobile phones, microwave appliances or other devices with strong
electromagnetic fields may result in impaired functioning.
• IP22: Protected against solid foreign objects of 12.5 mm diameter and greater. Protected against vertically falling
water drops when the device is tilted up to 15°.
• Batteries and electronic instruments must be disposed of in accordance with the locally applicable regulations, and
not as domestic waste.
• Do not use this device close to strong electromagnetic fields, such as mobile telephones or radio installations. Keep a
distance from such devices when using this unit.
TURNING ON THE THERMOMETER
To turn on the thermometer, push the button on the top; the display test is performed. Then at an ambient tempe rature
of less than 32°C / 89.6°F, an «L» and a flashing «°C/°F» appear at the upper right of the display. The thermometer is
now ready to use.
FUNCTION TEST
Proper functioning of the thermometer is tested automatically each time it is turned on. If a malfunction is detected
(measurement inaccuracy), this is indicated by «ERR» on the display, and a measurement becomes impossible. In this
case, the thermometer must be replaced.
USING THE THERMOMETER
During a measurement, the current temperature is displayed continuously. The «°C/°F» symbol flashes during this
period of time. If the «°C/°F» is no longer flashing, this means that the measured increase in temperature is now less
than 0.1°C / 0.2°F in 16 seconds and that the thermometer is ready for reading.
To prolong the life of the battery, turn it off after use by pressing the operating button briefly. Otherwise the thermo‑
meter will automatically turn off after about 10 minutes.
STORAGE OF MEASURED VALUES
If you hold the button down for more than 3 seconds when turning the thermometer on, the maximum temperature
stored automatically at the last measurement will be displayed. At the same time, a small «M» for memory will appear
at the right of the display. After 3 more seconds, this value will disappear and the thermometer will switch to the
normal measurement mode. Then the stored value is erased.
SWITCHING °C / °F
Press the button to turn the thermometer ON. The last measurement will display as mentioned in “Storage of Measured
Values” above. Once the «M» disappears and before «°C/°F» start to flash, press the button again and you can toggle
between °C or °F.

MEASURING METHODS
In the mouth (oral)
Position the thermometer in one of the two pockets under the tongue, to the left or right of the root of the tongue. The
measuring sensor must be in good contact with the tissue. Close your mouth and breath evenly through the nose to
prevent the measurement from being influenced by inhaled/exhaled air.
Approx. measuring time: 1 minute.
In the anus (rectal)
This is the most reliable measuring method, and is especially appropriate for infants and small children. Carefully insert
the tip of the thermometer 2 to 3 cm into the anal aperture.
Approx. measuring time: 1 minute.
In the armpit (axillary)
From a medical viewpoint, this method will always provide inaccurate readings, and should not be used if precise
measurements are required.
Approx. measuring time: 5 to 10 minutes.
CLEANING AND DISINFECTING
The thermometer is 100% waterproof and may be immersed in water or disinfectant solution,
then wipe it off with a moist towel. Please use one of the following disinfectants for cleaning, following the manu-
facturer’s instructions in each case.
Name of Disinfectant Dilution with Water Max. Duration Method
Isopropyl alcohol 70% 95.0% Immerse for 24 hours
Note: Any other cleaning solution, dilution or cleaning method can cause a malfunction of the thermometer.
The thermometer must never be boiled.
BATTERY DISPOSAL
Please break the end cap from the main body with a pair of pliers. Remove the battery and the PC board from the plastic
housing and dispose of separately. Battery cannot be replaced.
