Thank you for purchasing the Braun SensianTM 3 Non-contact forehead thermometer (BNT050). This thermometer is a high-quality product incorporating the latest technology and tested in accordance with international standards. With its unique technology, the product can provide a stable, accurate reading with each measurement. The thermometer performs a self-test every time it is switched on to always guarantee the accuracy of measurements.
Please read these instructions carefully before using this product and keep the instructions and the thermometer in a safe place.
Intended use and contraindications
This Non-contact forehead thermometer is a handheld, battery-powered, infrared thermometer intended for the intermittent measurement of human body temperature in a home-use environment on people of all ages, except pre-term and small-for-gestational-age babies, using the center of the forehead as the measurement site.
This thermometer is not intended for clinical use in a professional environment and is for home usage only.
This thermometer is not intended to interpret hypothermic temperatures. If the device displays a temperature of 35.7^ (96.3^) or less, and the individual is exhibiting atypical symptoms or behaviors, contact your physician or health care professional.
This thermometer is not intended for pre-term babies or small-for-gestational-age babies. Pre-term is defined as a baby, born before 37 weeks of pregnancy are completed. Small-for-gestational-age is defined as a newborn baby (birth to 4 weeks of age), born at 37 weeks or later, with a weight below the 10th percentile for newborn babies of the same gestational age.
Use of this thermometer is not a substitute for consultation with your doctor.
Earnings and precautions
Keep out of reach of children under 12 years.
NEVER use the thermometer for purposes other than those for which it has been intended. Please follow the general safety precautions when using on children.
NEVER immerse the thermometer into water or other liquids (not waterproof). For cleaning and disinfecting please follow the instructions in the "Care and cleaning" section.
DO NOT store this thermometer in temperature extremes below -25^ / -13^ or over 55^ / 131^ or in excessive humidity (above 95% non-condensing relative humidity).
If thermometer is stored in a location that is cooler or warmer than where it will be used, allow it to acclimate to the room temperature for 30 minutes before taking a measurement.
An individual must be inside and in the same room as the thermometer for 30 minutes before taking a measurement. If the individual is inside but in a room that is more than a few degrees warmer or cooler than the room the thermometer is in, it will impact the accuracy of the reading.
DO NOT use the thermometer if there are signs of damage on the scanner or on the thermometer itself. If damaged, DO NOT attempt to repair the product.
NEVER insert a sharp object into the scanner area or any other open surface on the thermometer.
This thermometer consists of high-quality precision parts. DO NOT drop the instrument. Protect it from severe impact and shock.
DO NOT use the device if it is damaged/degraded/loosened in any way. The effects of degraded sensors and electrodes, or loosened electrodes, that can degrade performance or cause other problems.
Temperature elevation may signal a serious illness, especially in neonates and infants, or in adults who are old, frail, or have a weakened immune system. Please seek professional advice immediately when a temperature elevation occurs on persons that are:
- Neonates and infants under 3 months (consult your doctor immediately if the temperature exceeds 37.4^ (99.4^)
- Individuals over 60 years of age (Fever may be blunted or absent in older individuals)
- Individuals having diabetes mellitus or a weakened immune system (e.g., HIV positive, cancer chemotherapy, chronic immunosuppressant treatment, splenectomy)
- Individuals who are bedridden (e.g., nursing home patient, stroke, chronic illness, paraplegia, quadriplegia, surgical recovery)
- A transplant patient (e.g., liver, heart, lung, kidney)
DO NOT allow children to take their temperatures unattended.
English
Please consult your physician if you see symptoms such as unexplained irritability, vomiting, diarrhea, dehydration, changes in appetite or activity, seizure, muscle pain, shivering, stiff neck, pain when urinating, etc., even in the absence of fever.
Even in the absence of fever, those who exhibit a normal temperature may still need to receive medical attention. Individuals who are on antibiotics, analgesics, or antipyretics should not be assessed solely on temperature readings to determine the severity of their illness.
DO NOT modify this equipment without the authorization of the manufacturer.
How does Braun Sensian™ 3 work?
The Braun Sensian™ 3 Non-contact forehead thermometer measures infrared energy radiated from the skin at the center of the forehead just above the eyebrows. This captured energy is collected through the lens and converted to an oral equivalent value.
The Braun Sensian™ 3 thermometer has been clinically tested and proven to be safe and accurate when used in accordance with its operating instruction manual.
Temperature taking hints
It is important to know each individual's normal temperature when they are well. This is the only way to accurately diagnose a fever. Take multiple readings when healthy to determine normal temperature.
A child's normal temperature can be as high as 37.7^ (99.9^) or as low as 36.1^ (97.0^) . Be sure to note this unit reads up to 0.6^ (1.0^) lower than a rectal digital measurement because it provides an oral equivalent reading.
NOTE: The thermometer and Individual being measured should be in the same ambient temperature for at least 30 minutes to avoid impacts to measurement accuracy.
ALWAYS hold the thermometer and the forehead steady when taking a reading. DO NOT move the thermometer until you hear the final beep (unless in silent mode).
Nursing mothers should not take a temperature measurement on themselves or have their temperature measured by another individual while or immediately after nursing a baby, as nursing can affect body temperature.
Individuals should not drink, eat, or be physically active before/while taking the measurement. Remove hats and wait 10 minutes before taking a measurement. Before taking a measurement, remove dirt or hair from the forehead area. Wait 10 minutes after cleaning the forehead before taking a measurement.
ALWAYS take the temperature exactly as directed. Temperature results may vary if positioned in the wrong location.
In the following situations it is recommended that three temperature measurements from the same location be taken, and the highest measurement of the three be used as the reading:
- Newborn infants in the first 100 days since birth.
Children under three years of age with a compromised immune system and for whom the presence or absence of fever is critical. - When the user is learning how to use the thermometer for the first time. (Until he/she has familiarized himself/herself with the instrument and obtains consistent readings.)
General precautions:
- Prior to measuring, remove any dirt or sweat from the forehead with a dry cloth.
- Avoid any cooling or warming cloths on the forehead for at least 30 minutes prior to measurement.
- Remove blankets and pillows away from the head and face prior measurement.
- DO NOT take temperature measurements over scar tissue, open sores, or abrasions.
- ALWAYS store the thermometer in a dry, clean environment. DO NOT store in areas with sharp objects that could scratch the sensor. Dirt, debris, and scratches will impact the accuracy of temperature readings.
