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 may only be used for the purposes described in these instructions. The manufacturer cannot be held liable for damage caused by incorrect application.
  • Never immerse this device in water or other liquids. For cleaning please follow the instructions in the «Cleaning and Disinfecting» section.
  • Do not use this device if you think it is damaged or notice anything unusual.
  • Never open this device.
  • A basic physiological effect called vasoconstriction can occur in the early stages of fever, resulting in a cool skin effect. The recorded temperature using this thermometer can, therefore, be unusually low.
  • If the measurement result is not consistent with the patient’s finding or unusually low, repeat the measurement every 15 minutes or double check the result by another core body  temperature measurement.
  • This device comprises sensitive components and must be treated with caution. Observe the storage and operating conditions described in the «Technical Specifications» section.
  • Ensure that children do not use this device unsupervised; some parts are small enough to be swallowed.
  • 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 it from:
    • extreme temperatures
    • impact and dropping
    • contamination and dust
    • direct sunlight
    • heat and cold
  • If the device is not going to be used for a prolonged period the batteries should be removed.

WARNING: The measurement results given by this device is not a diagnosis. It is not replacing the need for the consultation of a physician, especially if not matching the patient’s symptoms. Do not rely on the measurement result only, always consider other potentially occurring symptoms and the patient’s feedback. Calling a doctor or an ambulance is advised if needed.

WARNING: This device is not a toy! Keep out of reach of children and do not leave children alone during use.

How this Thermometer measures Temperature

This thermometer measures infrared energy radiated from the forehead as well as objects. This energy is collected through the lens and converted to a temperature value.

NOTE

  • Patients and thermometer should stay in similar room condition for at least 30 minutes.
  • Don’t take a measurement while or immediately after nursing a baby.
  • Don’t use the thermometer in high humidity environments.
  • Patients should not drink, eat or exercise before/while taking the measurement.
  • Don’t move the measurement device from the measuring area before hearing the termination beep.
  • 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.
  • Always take the temperature in the same location, since temperature readings may vary according to locations.
  • Doctors recommend rectal measurement for newborn infants within the first 6 months, as all other measuring methods might lead to ambiguous results. If using a non contact thermometer on those infants, we always recommend verifying the readings with a rectal measurement.
  • In the following situations it is recommended that three temperatures are taken with the highest one taken as the reading:
    1. Children under three years of age with a compromised immune system and for whom the presence or absence of fever is critical.
    2. When the user is learning how to use the thermometer for the first time until he/she has familiarized himself/ herself with the device and obtains consistent readings.
    3. If the measurement is surprisingly low.
  • Readings from different measuring sites should not be compared as the normal body temperature varies by measuring site and time of day, being highest in the evening and lowest about one hour before waking up. Normal body temperature ranges:
    • Axillar: 34.7 – 37.3 °C / 94.5 – 99.1 °F
    • Oral: 35.5 – 37.5 °C / 95.9 – 99.5 °F
    • Rectal: 36.6 – 38.0 °C / 97.9 – 100.4 °F
    • Microlife NC 400: 35.4 – 37.4 °C / 95.7 – 99.3 °F

Changing between Celsius and Fahrenheit

This thermometer can display temperature readings in either Fahrenheit or Celsius. To switch the display between °C and °F, press and hold the MODE button 6 for 3 seconds; the beeper icon is shown on the display. Press the MODE button again; the current measurement scale («°C» or «°F» icon) will be shown on the display AO. Change the measurement scale between °C and °F by pressing the MEMO-button 5. When the measurement scale has been chosen, press the START/IO button 7 to enter the «ready for measuring» mode; otherwise the device automatically switches to ready for measuring after 10 seconds.

How to recall 30 readings in Memory Mode

This thermometer can recall the last 30 readings with a record of both time and date.

  • Recall mode AP: Press the MEMO-button 5 to enter recall mode when the power is off. The memory icon «M» will flash.
  • Reading 1 – the last reading AQ: Press and release the MEMO-button 5 to recall the last reading. Number «1» and a flashing «M» are displayed.
    Pressing and releasing the MEMO-button 5 after the last 30 readings have been recalled will resume the above sequence from reading 1.
