The Braun ThermoScan thermometer has been carefully developed for accurate, safe and fast human body temperature measurements in the ear. The shape of the thermometer prevents it from being inserted too far into the ear canal to damage the eardrum. However, as with any thermometer, proper technique is critical to obtaining accurate temperatures. Therefore, please read all instructions carefully and thoroughly before using this product.

Do not expose the thermometer to temperature extremes (below – 20 º C / 4 º F or over 50 º C / 122 º F) nor excessive humidity (> 95 % RH). The probe window must be kept clean, dry, and undamaged at all times to ensure accurate readings. To protect the probe window, always keep the thermometer in the storage cover while transporting or when not in use. This thermometer must only be used with genuine Braun ThermoScan probe covers. To avoid inaccurate readings, always attach a new, clean probe cover for each temperature reading.

How does Braun ThermoScan work? Braun ThermoScan measures the infrared heat generated by the eardrum and surrounding tissue. To help ensure accuracy, the thermometer «scans» by taking 8 measurements in just one second and displaying the highest temperature. The displayed ThermoScan temperature is the actual measured ear canal temperature plus a mathematical adjustment to approximate the familiar oral range. However, this is not necessarily the same as an oral temperature measured at the same time.

Why measure in the ear? Clinical studies have shown that the ear is an excellent site for temperature measurement because temperatures taken in the ear reflect the body’s core temperature. Body temperature is regulated by the hypothalamus, which shares the same blood supply as the tympanic membrane. Changes in core body temperature, are usually seen sooner at the tympanic membrane than at other sites, such as the rectum, mouth or under the arm.

Advantages of taking temperatures at the ear versus traditional sites: ø Axillary temperature readings only reflect skin temperature which may not indicate the internal body temperature. ø Rectal temperatures often lag significantly behind internal body temperature changes, especially at times of rapidly changing temperatures. ø Oral temperatures are often influenced by eating, drinking, thermometer placement, breathing through the mouth, or the inability of the person to close their mouth completely.

Body temperature Normal body temperature is a range. The following table@ shows that ranges of normal also vary by site. Therefore, readings from different sites, even if taken at the same time, should not be directly compared. Axillary:

34.7 °C - 37.3 °C

94.5 °F - 99.1 °F

Oral:

35.5 °C - 37.5 °C

95.9 °F - 99.5 °F

Rectal:

36.6 °C - 38.0 °C

97.9 °F - 100.4 °F

ThermoScan ” :

35.8 °C - 38.0 °C

96.4 °F - 100.4 °F

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

Normal ThermoScan temperature ranges ” 0 - 2 years

36.4°C - 38.0 °C

97.5 °F - 100.4 °F

3 - 10 years

36.1°C - 37.8 °C

97.0 °F - 100.0 °F

11 - 65 years

35.9°C - 37.6 °C

96.6 °F - 99.7 °F

> 65 years

35.8°C - 37.5 °C

96.4 °F - 99.5 °F

The range of normal varies from person to person and can be influenced by many factors such as time of day, level of activity, medications and gender.

How to use Braun ThermoScan 1. Always use a new, clean probe cover for each measurement to help ensure an accurate reading. Attach a new, clean probe cover or, if already attached, press the /mem button.

The LCD ( liquid crystal display) is activated, showing all segments. When the ready symbol is displayed the thermometer is ready for use.

2. Perform an « ear tug » to straighten the ear canal. This gives the thermometer a clear view of the eardrum.

Children under 1 year: Pull the ear straight back. Children aged 1 year to adult: Pull the ear up and back.

3. While tugging the ear, fit the probe snugly into the ear canal as far as possible and press the activation button. Release it when you hear a beep. This is the Temp Beep that confirms the end of measurement. 4. Remove the thermometer from the ear canal. The LCD displays the temperature measured and the probe cover symbol.

5. Replace the probe cover after each measurement: Press the ejector button and put on a new, clean probe cover.

Only then, the probe cover symbol disappears from the display. The thermometer is now ready for use again.

6. If no button is pressed or no new probe cover is attached within 30 seconds, the thermometer will turn off automatically. Note: In the following situations, it is recommended that you take three temperatures in the same ear. If they differ, use the highest reading. ø ø

Infants in the first 90 days of life. Children under three years of age who have a condition such as a compromised immune system and for whom the presence or absence of fever is critical. When you are first learning to use the ear thermometer until you are comfortable with the technique and are obtaining consistent readings.

Important: As with any type of thermometer, slight temperature variations ( ± 0.2- 0.3 °C / ± 0.3 - 0.5 °F ) can occur, if consecutive measurements are taken. 7

ø

The right ear reading may differ from the reading taken at the left ear. Therefore, always take the temperature in the same ear.

ø

The ear must be free from obstructions or excess earwax buildup to take an accurate reading.

ø

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 prior to taking a temperature.

ø

For persons wearing hearing aids or ear plugs, remove the device and wait 20 minutes prior to taking a temperature.

ø

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

Care and cleaning Braun ThermoScan probe covers are intended for single use only! To ensure accurate readings, always use Braun ThermoScan disposable probe covers with the Pro 3000 thermometer. Damaged, perforated, or soiled probe covers can lead to inaccurate temperature readings. Additionally, the accuracy of your temperature readings can be affected by damage to the probe window, or the presence of dirt and ear wax on the probe window.

Probe Window To assure a high level of accuracy, it is very important to keep this window clean, dry and undamaged. Fingerprints, earwax, dust and other soiling compounds reduce transparency of the window and result in lower temperature readings. If the thermometer is accidentally placed in the ear without a probe cover installed, the window must be cleaned immediately. Additionally, the window and/or probe tip area should never be modified, changed, or adjusted. These changes will affect calibration and accuracy of the thermometer. To clean the window, gently wipe its surface with a cotton swab slightly moistened with alcohol and immediately wipe dry with a clean cotton swab. After cleaning, allow at least 5 minutes drying time before taking temperatures. Make sure probe window is clean and dry. Avoid touching the window except when cleaning is required. If the window is damaged, the thermometer must be returned to Welch Allyn for service. Note: Do not use any chemical other than alcohol to clean the probe window.

Thermometer Use a soft, cloth slightly moistened with alcohol to clean the thermometer display and exterior. Do not use abrasive cleaners. Never submerge the thermometer in water or any other liquid. Store thermometer and probe covers in a dry location free from dust and contamination and away from direct sunlight. The ambient temperature at the storage location should remain fairly constant and within the range of 10 °C - 40°C ( 50 °F to 104 °F ).

Troubleshooting Error message

Situation

Solution

No probe cover is attached and activation button was pressed while probe was in the ear.

Make sure probe window is clean; refer to section «Care and cleaning» i f necessary. Attach new, clean probe cover to stop error beeps.

Ambient temperature is not within the allowed operating range of 10 °C - 40°C (50 °F to 104 °F ) or changing too rapidly.

Allow the thermometer to remain in a room for 30 minutes where the temperature is between 10 °C and 40°C ( 50 °F to 104 °F ).

Temperature taken is not within displayed temperature range (20 °C - 42.2 °C / 68 °F 108 °F ).

Make sure new, clean probe cover is attached and thermometer is properly inserted. To clear the error message, attach a new, clean probe cover or press the /mem button. Then, take a new temperature.
