BRAUN ThermoScan IRT 3020 CO Compact Ear Thermometer Instruction Manual

BRAUN ThermoScan IRT 3020 CO Compact Ear Thermometer

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 use instructions carefully and thoroughly.

Important

• The operating ambient temperature range for this thermometer is 10 – 40 °C (50 – 104 °F).
• Do not expose the thermometer to temperature extremes (below –20 °C / –4 °F or over 50 °C / 122 °F) or excessive humidity (> 95 % RH).
• This thermometer must only be used with genuine Braun ThermoScan Lens Filters. Other lens filters can lead to inaccuracy.
• To avoid inaccurate measurements always use this thermometer with a new, clean lens filter.
• If the thermometer is accidentally used without a lens filter, clean the lens after use (see «Care and cleaning»).
• Keep lens filters out of reach of children.
• This thermometer is intended for household use only.
• Use of this thermometer is not intended as a substitute for consultation with your physician.

Body temperature

Normal body temperature is a range. The following table shows that this normal range also varies by site. Therefore, measurements from different sites should not be directly compared.

Normal temperature ranges of different sites in the body:

• Axillary 1: 34.7 – 37.3 °C 94.5 – 99.1 °F
• Oral 1: 35.5 – 37.5 °C 95.9 – 99.5 °F
• Rectal 1: 36.6 – 38.0 °C 97.9 – 100.4 °F
• ThermoScan 2: 35.8 – 38.0 °C 96.4 – 100.4 °F

A person’s normal temperature range tends to decrease with age. The following table shows normal ThermoScan ranges by age.

Normal ThermoScan ranges by age 2:

• 0 – 2 years 36.4 – 38.0 °C 97.5 – 100.4 °F
• 3 – 10 years 36.1 – 37.8 °C 97.0 – 100.0 °F
• 11 – 65 years 35.9 – 37.6 °C 96.6 – 99.7 °F

• 65 years 35.8 – 37.5 °C 96.4 – 99.5 °F

Everyone has their normal temperature range, and this range also varies throughout the day. It is easy to determine the normal temperature range using the Braun ThermoScan. Practice taking temperatures on yourself and healthy family members to determine your normal temperature ranges. Note: When consulting your physician, communicate that the ThermoScan temperature is a temperature measured in the ear and if possible, quote the individual’s normal ThermoScan temperature range as an additional reference.

How to use

How to use your Braun ThermoScan

1. To achieve accurate measurements, make sure a new, clean lens filter (2) is in place before each measurement.
2. To turn the thermometer on, push the «start» button (4).
   • During an internal self-check, the display shows all segments. Then the last temperature taken will be displayed together with «MEM».
   • As soon as this ready symbol appears, you can start the measuring process.
3. Perform an ear tug to straighten the ear canal. This gives the thermometer a clear view of the eardrum.
   • An ear tug is best performed by using your free hand to grasp the outer edge of the top half of the ear. To take your own temperature, wrap your free hand around the back of your head and tug your ear from behind.
   • Children under 1 year: Pull the ear straight back.
   • Children aged 1 year to adult: Pull the ear up and back.
4. While tugging the ear, fit the probe (3) snugly into the ear canal, then push the «start» button (4). A short beep will signal the start of the measuring process.
   • After one second a longer beep will signal the end of the measuring process. The result is shown on the display (6).
5. For the next measurement, remove the used lens filter and put on a new, clean lens filter. Clear the display by pushing the «start» button once. Fit the probe snugly into the ear canal, then push the «start» button.

The Braun ThermoScan ear thermometer turns off automatically after 60 seconds of inactivity.

Temperature taking hints

• A measurement taken in the right ear may differ 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 influence ear temperatures, including when an individual has:
  • been lying on one ear or the other
  • had their ears covered
  • been exposed to very hot or very cold temperatures, or
  • been recently swimming or bathing.
• In these cases, remove the individual from the situation and wait 20 minutes before taking a temperature.
• If ear drops or other ear medications have been placed in the ear canal of one ear, take the temperature in the untreated ear.

Care and cleaning

The probe tip is the most delicate part of the thermometer. It has to be clean and intact to ensure accurate readings.

• If the thermometer is accidentally used without a lens filter, clean the probe tip as follows:
• Very gently wipe the surface with a cotton swab or soft cloth moistened with alcohol.
• Once the alcohol has dried completely, a new lens filter can be put on and a temperature measurement is taken. If the probe tip is damaged, contact Braun.
• Use a soft, dry cloth to clean the thermometer display and product exterior. Do not use abrasive cleaners. Never submerge this thermometer in water or any other liquid.
• Store the thermometer and lens filters in a dry location free from dust and contamination and away from direct sunlight.
• Additional lens filters (LF 40) are available at most stores selling Braun ThermoScan.

Troubleshooting

Changing the temperature scale

• Your Braun ThermoScan is delivered to you with the Celsius (°C) temperature scale activated. If you wish to switch to Fahrenheit (°F), proceed as follows:
• Make sure the thermometer is turned off. Press and hold down the «start» button. After about 8 seconds the display will show this sequence: «°C» / «°F» /…
• Release the «start» button when «°F» is shown.
• There will be a short beep to confirm the new setting, the thermometer then turns off automatically.

Replacing the battery

• The thermometer is supplied with one 1.5 V type AAA (LR03). For best performance, we recommend Duracell ® alkaline batteries. Insert a new battery when the battery symbol appears on the display.
• Open the battery compartment. Remove the battery and replace it with a new battery, making sure the poles are in the right direction. Slide the battery door back until it snaps in place.
• To protect the environment, dispose of empty batteries at appropriate collection sites according to national or local regulations.

Calibration

• The thermometer is initially calibrated at the time of manufacture.
• If this thermometer is used according to the use instructions, periodic readjustment is not required.
• If at any time you question the accuracy of temperature measurements, please contact Braun Infoline (see page 2).
• The manufacturing date is given by the LOT number located in the battery compartment. The first number after LOT represents the last digit of the year of manufacture.
• The last two digits give the week of manufacture. An example: LOT 503 – this product has been manufactured in the week 03 of the year 2005.
