• The minimum measurement time until the beep is heard must be maintained without exception!
• Ensure that children do not use the instrument unsupervised; some parts are small enough to be swallowed.
• Protect the instrument from impact and dropping!
• Avoid bending the tip more than 45°!
• Avoid ambient temperatures above 60°C. NEVER boil the instrument! •Use only the commercial disinfectants listed in the section «Cleaning and Disinfecting» to clean the instrument. The instrument must be intact when immersed in liquid disinfectant.

Turning on the Thermometer

To turn on the thermometer, press the ON/OFF button ; a short beep signals «thermometer ON». A display test is performed. All segments should be displayed.
The last measurement reading will be shown on the display automatically for 2 seconds with the «M» icon.
Then at an ambient temperature of less than 32°C, an «L» and a flashing «°C» or «°F» appear at the display field . The thermometer is ready for use now.

Function Test

Correct 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

Place the thermometer at the measuring site before switching it on in order to achieve the most accurate result. Choose the preferred measuring method. When taking a measurement, the current temperature is continuously displayed and the «°C» symbol flashes. If the beep is heard 10 times and the «°C» is no longer flashing, the predictive end-temperature has been determined and the thermometer can be read now.
10 short beeps and a red LCD backlight alert the patient that he/she may have a temperature equal to or higher than 37.5°C.
To prolong the battery life, turn off the thermometer by briefly pressing the ON/OFF button . Otherwise the thermometer will automatically turn off after about 3 minutes.

Changing from °C to °F

With the thermometer turned off, press and hold the ON/OFF button for 5 seconds until «M» disappears. Shortly press the ON/OFF button to switch between °C or °F. Wait 3 seconds till «°C» or «°F» starts blinking and press ON/OFF button again to confirm your selection. The thermometer is set to your selection for future use.

Measuring methods / Normal body temperature

• In the mouth (oral) / 35.5 - 37.5°C
  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 breathe evenly through the nose to prevent the measurement from being influenced by inhaled/ exhaled air.
  Approx. measuring time: 10 seconds!
• In the anus (rectal) / 36.6 - 38.0°C
  This is the most reliable measuring method, and is especially suitable for infants and small children. Carefully insert the measuring sensor of the thermometer 2 to 3 cm into the anal aperture.
  Approx. measuring time: 10 seconds!
• In the armpit (axillary) / 34.7 - 37.3°C
  To receive more reliable results we recommend measuring temperature orally or rectally.

Cleaning and Disinfecting

Name: Isopropyl alcohol 70%; immerse: max. 24 hours.

Battery Replacement

When the « » symbol (upside-down triangle) appears at the display field, the battery is flat and needs replacing. To replace the battery remove the battery compartment cover from the thermometer. Insert the new battery with the + at the top. Make sure you have a battery of the same type to hand. Batteries can be purchased at any electrical store.
