Product Usage Instructions

Before using the thermometer, it is recommended to read the instructions carefully and follow the safety precautions mentioned.

Here are the usage instructions:

1. Ensure the device is clean by following the cleaning instructions provided before the first use for personal hygiene.
2. Do not attempt rectal measurements on individuals with rectal disorders, as it may worsen the condition.
3. Choose the desired mode of measurement (oral, rectal, or axillary) based on the intended use.
4. Press the ON/OFF button to turn on the thermometer.
5. Place the measuring sensor or measuring tip in the appropriate location (mouth, rectum, or armpit) for temperature measurement.
6. Wait for the temperature reading to be displayed on the screen.
7. Record the temperature if necessary.
8. After use, clean and disinfect the entire surface of the thermometer using the recommended cleaning instructions.

Note: It is important to only use the thermometer for measuring body temperature in the specified areas (oral, rectal, or axillary). Avoid measuring temperature in other areas such as the ear, as it may result in inaccurate readings and potential injuries. Do not use the device if it is damaged or shows any abnormalities.

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.

• The minimum measurement time until the beep is heard must be maintained without exception! Consider that different measurement locations may require continued measuring even after the beep, see section «Measuring methods / Normal body temperature».

• 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. Be aware of the risk of strangulation in case this device is supplied with cables or tubes.

• 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.

Read the instructions carefully before using this device.

Type BF applied part

Turning on the Thermometer

To turn on the thermometer, press the ON/OFF button 1; a long beep signals «thermometer ON». A display test is performed. All segments should be displayed. Followed by the last measurement shown for 2 seconds. Then «– -» and a flashing «°C» or «°F» appear at the display field 2. 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
  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, this means that the measured increase in temperature is less than 0.1 °C in 5 seconds. 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.

• Changing from °C to °F
  With the thermometer turned off, press and hold the ON/OFF button 1 for 5 seconds until «°C» or «°F» flashes. Now press the ON/OFF button to switch between °C and °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 armpit (axillary) / 34.7 – 37.3 °C
  Wipe the underarm with a dry towel. Place the measuring sensor 4 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, regardless of the beep sound.

• In the mouth (oral) / 35.5 – 37.5 °C
  Do 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 4 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: 30 seconds!

• In the anus (rectal) / 36.6 – 38.0 °C
  Attention: 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 4 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: 30 seconds!

• 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 5 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:
  Additionally, you may apply probe covers (available as accessory). Contact Microlife for more details concerning further disinfectants for your thermometer model.

Battery Replacement

When the « » symbol (upside-down triangle) appears in the display, the battery is flat and needs replacing. To replace the battery remove the battery compartment cover 3 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.
