Monitoring of instruments

EU countries except Germany:
Legal regulations for monitoring instruments apply to all EU countries except Germany.

Countries outside the EU:
For any countries where no legal regulations exist for monitoring instruments, it is recommended to examine the accuracy of measuring instruments in 2-year intervals.

Turning on the thermometer

To turn on the thermometer, push the button over the display window; a short signalling tone [beep] signals «thermometer ON.» A display test is performed. Then at an ambient temperature of less than 32°C, an «L» and a flashing «°C» appear at the upper right of the display. The thermometer is now ready for 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» symbol flashes during this period of time. If the signalling tone sounds (beep-beep-

beep-beep 10 times) and the «°C» is no longer flashing, this means that the measured increase in temperature is now less than 0,1°C 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 thermometer 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.

Measuring methodes

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 has a waterproof tip. For disinfecting please wipe with a alcohol moist towel.

Battery Replacement

When the «» symbol (upside-down triangle) appears in the lower right of the display, the battery is exhausted and needs replacing. For the battery replacement please remove the compartment lid of the thermometer. Replace the exhausted battery by positioning the + at the top. Make sure a battery of the same type is on hand. Batteries can be purchased at any electrical goods shops. For battery disposal please refer to «safety instructions».
