Important Safety Instructions

• Follow instructions for use. This document provides important product operation and safety information regarding this device. Please read this document thoroughly before using the device and keep for future reference.
• This device is only to be used for measuring human body temperature through oral, rectal or axillary. Do not attempt to take temperatures at other sites, such as in the ear, as it may result in false readings and may lead to injury.
• Do not use this device if you think it is damaged or notice anything unusual.
• We recommend cleaning this device according to the cleaning instructions before first use for personal hygiene.
• For safety reasons (risk of rectal perforation) rectal measurement in children younger than 3 years must be performed only by trained health care personnel (professional user). Use another measurement method instead. For rectal fever measurement in small children younger than 3 years, thermometers with a flexible tip are available.
• Do not attempt rectal measurements on persons with rectal disorders. Doing so may aggravate or worsen the disorder.
• Ensure that children do not use this device unsupervised; some parts are small enough to be swallowed.
• The battery is well sealed inside the thermometer to reduce the risk to be swallowed by children.
• Do not use this device close to strong electromagnetic fields such as mobile telephones or radio installations. Keep a minimum distance of 3.3 m from such devices when using this device.
• Protect the device from impact and dropping!
• Avoid ambient temperatures above 60 °C. NEVER boil this device!
• Use only the commercial disinfectants listed in the section «Cleaning and Disinfecting» to clean the device to avoid damage to the device.
• We recommend this device is tested for accuracy every two years or after mechanical impact (e.g. being dropped). Please contact your local Microlife-Service to arrange the test.

WARNING: The measurement result given by this device is not a diagnosis! Do not rely on the measurement result only.

Batteries and electronic devices must be disposed of in accordance with the locally applicable regulations, not with domestic waste.

Turning on the Thermometer

To turn on the thermometer, press the ON/OFF button 1. A display test is performed. All segments should be displayed. Then at an ambient temperature of less than 32 °C, an «L» and a flashing «°C» appear at the display field 2. The thermometer is now ready for use.

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

Choose the preferred measuring method. When taking a measurement, the current temperature is continuously displayed and the «°C» symbol flashes. If the «°C» is no longer flashing, this means that the measured increase in temperature is less than 0.1 °C in 16 seconds and that the thermometer can now be read. To prolong the battery life, turn off the thermometer by briefly pressing the ON/OFF button 1. Otherwise the thermometer will automatically turn off after about 10 minutes.

Storage of Measured Values

If the ON/OFF button 1 is pressed for more than 3 seconds when turning on the thermometer, the automatically stored maximum temperature during the last measurement will be displayed. At the same time, a «M» for memory will appear on the display. About 2 seconds after the button is released, the temperature value disappears and the thermometer is ready for measurement.

Measuring methods / Normal body temperature

In the armpit (axillary) / 34.7 – 37.3 °CWipe the underarm with a dry towel. Place the measuring sensor 3 under the arm into the center of the armpit so the tip is touching the skin and position the patient’s arm next to the patient’s body. This ensures that the room air does not affect the reading. Because the axillary takes more time to reach its stable temperature wait at least 5 minutes.In the mouth (oral) / 35.5 – 37.5 °CDo not eat or drink anything hot or cold 10 minutes before the measurement. The mouth should remain closed up to 2 minutes before starting a reading. 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 3 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. If this is not possible due to blocked airways, another method for measuring should be used.Approx. measuring time: 1 minute!In the anus (rectal) / 36.6 – 38.0 °CAttention: For the prevention of rectal perforation in children (younger than 3 years), we recommend using another measuring method, or the use of a thermometer with flexible tip. Carefully insert the measuring sensor 3 of the thermometer 2 to 3 cm into the anal aperture. The use of a probe cover and the use of a lubricant is recommended. If you are unsure of this measurement method, you should consult a professional for guidance/training.Approx. measuring time: 1 minute!

Cleaning and Disinfecting

For disinfection in home use environment, use a 70% Isopropyl alcohol swab or a cotton tissue moistened with 70% Isopropyl alcohol to wipe surface pollutants off the thermometer probe. Always start wiping from the end of the thermometer probe (approx. at the middle of the thermometer) towards the thermometer tip. Afterwards the entire thermometer (see number 4 in the drawing) should be immersed in 70% Isopropyl alcohol for at least 5 minutes (max. 24 hours). After immersion, let the disinfectant dry off for 1 minute before next use.For professional use: You may apply probe covers (available as accessory). Contact Microlife for further details concerning suitable disinfectants for your thermometer model.

Battery Exhaustion

When the  symbol (upside-down triangle) appears on the right side of the display, the battery is exhausted and the thermometer needs to be replaced. For battery disposal please refer to «Important Safety Instructions».
