Braun ThermoScan IRT 6520 Infrared Ear Thermometer Manual

Product Description

IRT 6520

IRT 6020

The Braun ThermoScan thermometer has been carefully developed for accurate, safe and fast temperature measurements in the ear.

The shape of the thermometer probe prevents it from being inserted too far into the ear canal, which can hurt the eardrum.

However, as with any thermometer, proper technique is critical to obtaining accurate temperatures. Therefore, read the instructions carefully and thoroughly.

The Braun ThermoScan thermometer is indicated for intermittent measurement and monitoring of human body temperature for people of all ages. It is intended for household use only.

Use of IRT 6520 along with Age Precision™ feature is not intended as a substitute for consultation with your physician.

WARNINGS AND PRECAUTIONS

The operating ambient temperature range for this thermometer is 10 – 40°C (50 – 104°F). Do not expose the thermometer to temperature extremes (below -25°C / -13°F or over 55°C / 131°F) or excessive humidity (>95% RH). This thermometer must only be used with genuine Braun ThermoScan lens filters (LF 40).

To avoid inaccurate measurements always use this thermometer with a new, clean lens filter attached.

If the thermometer is accidentally used without a lens filter attached, clean the lens (see «Care and cleaning» section). Keep lens filters out of reach of children.

This thermometer is intended for household use only. This product is not intended to diagnose any disease, but is a useful screening tool for temperature. Use of this thermometer is not intended as a substitute for consultation with your physician.

The Age Precision™ feature is not intended for pre-term babies or small-for-gestational age babies.
The Age Precision™ feature is not intended to interpret hypothermic temperatures. Do not allow children under 12 to take their temperatures unattended.

Do not modify this equipment without authorization of the manufacturer.

Parents/guardians should call the pediatrician upon noticing any unusual sign(s) or symptom(s).
For example, a child who exhibits irritability, vomiting, diarrhea, dehydration, seizure, changes in appetite or activity, even in the absence of fever, or who exhibits a low temperature, may still need to receive medical attention.

Children who are on antibiotics, analgesics, or antipyretics should not be assessed solely on temperature readings to determine the severity of their illness.

Temperature elevation as indicated by Age Precision™ may signal a serious illness, especially in adults who are old, frail, have a weakened immune system, or neonates and infants. Please seek professional advice immediately when there is a temperature elevation and if you are taking temperature on:

Fever may be blunted or even absent in elderly patients.

This thermometer contains small parts that can be swallowed or produce a choking hazard to children.
Always keep the thermometer out of children's reach.

Body temperature

Normal body temperature is a range. It varies by site of measurement, and it tends to decrease with age. It also varies from person to person and fl uctuates throughout the day. Therefore, it is important to determine normal temperature ranges. This is easily done using Braun ThermoScan. Practice taking temperatures on yourself and healthy family members to determine the normal temperature range.

Note: When consulting your physician, communicate that the ThermoScan temperature is a temperature measured in the ear and if possible, note the individual's normal ThermoScan temperature range as additional reference.

Age Precision color-coded display

Clinical research shows the definition of fever changes as newborns grow into little kids and little kids grow into adults¹.

Braun's Age Precision™ color-coded display takes the guesswork out of interpreting temperature for the entire family.

Simply use the Age Precision™ button to select the appropriate age setting, take a temperature and the color-coded display will glow green, yellow or red to help you understand the temperature reading.

How does Braun ThermoScan work?

Braun ThermoScan measures the infrared heat generated by the eardrum and surrounding tissues. To help avoid inaccurate temperature measurements, the probe tip is warmed to a temperature close to that of the human body. When the Braun ThermoScan is placed in the ear, it continuously monitors the infrared energy. The measurement is finished and the result displayed when the thermometer detects that an accurate temperature measurement has been taken.

Why measure in the ear?

The goal of thermometry is to measure core body temperature², which is the temperature of the vital organs. Ear temperatures accurately refl ect core body temperature³, since the eardrum shares blood supply with the temperature control center in the brain⁴, the hypothalamus. Therefore, changes in body temperature are refl ected sooner in the ear than at other sites. Axillary temperatures measure skin temperature and may not be a reliable indicator of core body temperature. Oral temperatures are infl uenced by drinking, eating and mouth breathing. Rectal temperatures often lag behind changes in core body temperature and there is a risk of cross-contamination.

How to use

1. Remove the thermometer from the protective case.
   
   Remove protective cap.
   
2. Push the Power button .
   During an internal self-check, the display shows all segments. Then the last temperature taken will be displayed for 5 seconds.

Temperature-taking hints

Always replace disposable lens filters to maintain accuracy and hygiene. The right ear measurement may diff er from the measurement taken in the left ear. Therefore, always take the temperature in the same ear. The ear must be free from obstructions or excess earwax build-up to take an accurate reading.

External factors may infl uence ear temperatures, including when an individual has:

Factor	Affects
Poor probe placement
Used lens filter
Dirty lens

In the cases below, wait 20 minutes prior to taking a temperature.

Factor	Affects
Extreme hot and cold room temperature
Hearing aid
Lying on pillow

Use the untreated ear if ear drops or other ear medications have been placed in the ear canal.
