How does Braun ThermoScan work? The Braun ThermoScan thermometer 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? The goal of thermometry is to measure core body temperature, which is the temperature of the vital organs. Clinical studies have shown that the ear is an excellent site to measure body temperature, since ear temperatures reflect core body temperature. The eardrum shares blood supply with the temperature control center in the brain, the hypothalamus, allowing changes in body temperature to be reflected sooner in the ear than at other sites. 4 · Axillary temperatures reflect skin temperature which may not indicate core body temperature. · Oral temperatures are influenced by drinking, eating and breathing through the mouth. · Rectal temperatures often lag behind changes in core body temperature and there is a risk of cross-contamination. Body temperature Normal body temperature is a range. The following table1 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: Oral: Rectal: ThermoScan2: 94.5 °F - 99.1 °F 95.9 °F - 99.5 °F 97.9 °F - 100.4 °F 96.4 °F - 100.4 °F 34.7 °C - 37.3 °C 35.5 °C - 37.5 °C 36.6 °C - 38.0 °C 35.8 °C - 38.0 °C · Also, a person's normal temperature range tends to decrease with age. The following table shows normal ThermoScan ranges by age. Normal ThermoScan temperature ranges2 0 - 2 years 3 - 10 years 11 - 65 years > 65 years 97.5 °F - 100.4 °F 97.0 °F - 100.0 °F 96.6 °F - 99.7 °F 96.4 °F - 99.5 °F 36.4°C - 38.0 °C 36.1°C - 37.8 °C 35.9°C - 37.6 °C 35.8°C - 37.5 °C · However, the range of normal also varies from person to person and fluctuates throughout the day. It is therefore important to determine your and your family members' normal temperature ranges. This is easily done using Braun ThermoScan. Practice taking temperatures on yourself and healthy family members to determine their normal temperature ranges. 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. 1.

Always make sure a new, clean lens filter is in place to help ensure an accurate reading. The thermometer will not function without a lens filter attached (see Changing the lens filter). 2. 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. 6 To help ensure an accurate temperature reading, use the following technique: If you are right handed, hold the thermometer in the right hand and take the temperature in the right ear. If you are left handed, hold it in the left hand and use the left ear. 3. 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. 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 grab your ear from behind. 4. 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. 5. Remove the thermometer from the ear canal. The LCD displays the temperature measured. 6. Replace the lens filter after each measurement: press the ejector button and put on a new, clean lens filter. 7. A new measurement can be taken as long as the ready symbol is shown. If no button is pressed within 2 minutes, the thermometer will turn off automatically. 7 Note: In the following situations, it is recommended that you take three temperatures in the same ear. If they differ, use the highest reading. · 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 ( ± 0.3 - 0.5 °F / ± 0.2 - 0.3 °C) can occur, if consecutive measurements are taken. Temperature taking hints · The right ear reading may differ from the reading taken at the left ear. Therefore, always take the temperature in the same ear. · The ear must be free from obstructions or excess earwax buildup 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 prior to taking a temperature. 8 Memory mode The last temperature taken before the thermometer powers down is stored in memory. To enter the memory mode, press the /mem button. Even in memory mode, a new temperature can be taken provided that the ready symbol is shown. IRT 3020 The last stored temperature is displayed along with the MEM symbol. To quit the memory mode, press the /mem button again. IRT 3520 This model allows you to store up to 8 temperatures. When pressing the /mem button, the display shows the memory cell number (e.g. MEM 1). When releasing the /mem button, the stored temperature is displayed. Each time the /mem button is pressed, a new memory cell is displayed (up to MEM 8). An empty memory cell shows «- - - °F». Only the first empty memory cell will be displayed. To quit the memory mode, press the /mem button again after reaching MEM 8 or «- - - °F». Memory clear Press the /mem button for 5 seconds to clear the temperatures stored in memory.

Then press and release the activation button to switch over to the «change temperature scale» mode. · By pressing the activation button again, the Celsius scale is activated, «°C» is displayed on the LCD. Each further pressing of the activation button toggles the scale between °C and °F. IRT 3020 · Release the /mem button to return to the ready symbol . All temperatures stored in memory will automatically be converted to the selected scale when displayed on the LCD. IRT 3520 Changing the lens filter The thermometer is supplied with a lens filter in place. To assure accuracy and sanitary practice, Braun recommends replacing the lens filter after each use. To install a new lens filter, first remove the one in place by pressing the lens filter ejector. Check the lens for any damage. Then take a new lens filter from the box, and holding it by its edges, slide it onto the probe until it snaps in place. Caution: Do not touch the tip of the probe or lens filters when installing. Fingerprints, ear wax, dust and other soiling compounds reduce the transparency, resulting in lower temperature readings (see also Care and cleaning). Should you run out of lens filters and need to take a temperature, you may use the following lens filter cleaning procedure: · Clean the lens filter without removing it from the thermometer with a soft cloth or cotton swab moistened with alcohol. Do not use hot or boiling water. · Dry completely with a soft cloth before reusing. · Replace lens filter as soon as possible with a new one (LF 40 ). · Additional lens filters (LF 40 ) are available at most stores 10 carrying Braun ThermoScan thermometers or at Braun Service Centers. · If you have accidentally placed the thermometer in your ear without a lens filter in place, be sure and clean the probe (see «Care and cleaning» and then apply a clean lens filter. 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 ever accidentally used without a lens filter, clean the lens as follows: · Hold the appliance with the probe tip facing down to prevent liquid from entering the probe tip area. Very gently wipe the surface with a cotton swab or soft cloth moistened with alcohol. · After cleaning, allow at least 45 minutes drying time before reattaching a new, clean lens filter and taking a temperature. If the probe tip is damaged, contact Braun. Use a soft, dry cloth 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 lens filters 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 50 °F to 104 °F (10 °C - 40 °C). Always keep cleaning solutions and rubbing alcohol away from children. Replacing the batteries The thermometer is supplied with two 3 V lithium ...
