15. Patients should not drink, eat, or be physically active before/while taking the measurement.

Product Description

Overview

1. Infrared Thermometer measures the body temperature based on the infrared energy emitted from the eardrum or the forehead. Users can quickly get measurement results after positioning properly the temperature probe in the ear canal or forehead.
   Normal body temperature is a range. The following tables show that this normal range also varies by site. Therefore, readings from different sites should not be directly compared. Tell your doctor what type of thermometer you used to take your temperature and on what part of the body. Also bear this in mind if you are diagnosing yourself.Measuring part| Normal temperature range
   ---|---
   Forehead temperature| 36.1°C – 37.5°C (97°F – 99.5°F)
   Ear temperature| 35.8OC – 38°C (96.4°F -100.4OF)
   Oral temperature| 35.5°C – 37.5°C (95.9°F – 99.5°F)
   Rectal temperature| 36.6OC – 38°C (97.9°F – 100.4°F)
   Axillary temperature| 34.7OC – 37.3°C (94.5°F – 99.1°F)

Structure

The device consists of an enclosure, button, a temperat- ure sensor, Infrared temperature-measuring element, microcomputer controlled circuit, LCD, backlight and a buzzer.

Operating principle

The infrared thermometer‘s working principle is based on the fourth-power law: infer objects’ radiation temperature by measuring objects’ radiation infrared energy. Thermopile sensors can convert infrared energy into thermoelectricity, and output as a detected signal after signal processing.

1-Subject     2-Object lens     3-Heat plate    4-ThermocoupIe 5-Eye Len
Figure 1

The infrared temperature sensor detects infrared energy emitted by the eardrum. A built-in lens focus- es the collected energy, which is then converted into a temperature reading by the thermopiles and measurement circuits.

How to use your thermometer

In order to avoid the inaccuracy:

1. Please ma he sure that the device will be used indoors away from strong wind.
2. Please make sure that there is no intense emotion and movement before measuring.
3. If the device is transferred from one condition to another, which has a different ambient temperature, it is suggested to deposit for more than 30 minutes.
4. If the tester is transferred from one condition to another, which has a different ambient temperature, it is suggested to have a rest for more than 10 minutes.
5. Do not hold the device for a long time, as it is highly sensitive to heat. The device has undergone clinical tests, it is safe and accurate when used in accordance with the operation manual.

Take your forehead temperature

1. When using the thermometer for the first time, please load the batteries.
2. Press and release the Measure/Mute-unmute button in one second to power on and LED light will be on.
3. Use the toggle switch to choose age classification ((1):3 months-6 years, (2) 6yeais-12years,(3): above 12 years).
4. Then point the temperature probe at the center of the forehead, with a distance of 0-3 cm(0-1.18 inches).
5. Press and release the Measure/Mute-unmute button in 1 second. The beep is heard, you can now read the value.
   NOTE: The forehead measurement is active reading. The measured forehead temperature can fluctuate up to 1 °F/0.5  °C from your actual body temperature. Please be aware of the factors that influence the accuracy as described in the section “Temperature taking tips” and “WARNINGS AND PRECAUTIONS” .

 If the forehead area is covered with hair, sweat or dirt, please clean the area beforehand to improve the reading accuracy.
 Always check if the lens is clean.
Always make sure the user and the thermometer are in the same room for at least 30 minutes prior to the measurement.

Take your ear temperature

1. Press the Measure/Mute-unmute button to power

2. Take off the probe
   Then fit the probe snuggly into the ear canal.

3. Press and release the Measure/Mute-unmute button in 1 second, the beep is heard, you can now read the value.

Please make sure that the ear is clean, with no earwax or obstructions.
The reading from the right ear may differ to left ear. Therefore, always take readings from the same ear.
Note:
Children under 1 year: Pull the ear straight back.
Children aged 1 year to adult: Pull the ear up and
Do not force the thermometer into the ear canal. Otherwise, the ear canal may get injured.
When taking the temperature on an adult, gently pull the ear up and back to make sure the ear canal is straight, so that the temperature probe can receive an infrared ray from the eardrum.
Be careful when taking the temperature on a child, whose ear canal is small.

After a measurement

Once the reading has been completed, remove the thermometer away from the forehead/ear and observe the temperature.
After each measurement, you can enter the recall mode and query earlier temperature readings.

Do not hold the thermometer for a long time, because it is sensitive to the ambient temperature.
After each measurement, clean the temperature probe with a soft cloth and put the thermometer in a dry and well-ventilated place.
You should wait at least 10 seconds between each measurement.
It is dangerous to make a self-diagnosis or self-treatment based on the obtained measurement results. For such purposes, please consult a doctor.

Read your temperature

Replace the battery.

Put two AAA bakeries correctly into the companion.

Remove the batteries if the thermometer will not be used for more than two months.

Temperature taking tips

1. It is important to know each individual ‘s normal temperature when they are well. This is the only way to accurately diagnose a fever. Record readings twice a day (early morning and late afternoon). Take the average of the two temperatures to calculate normal oral equivalent temperature. Always take the temperature in the same location, since the temperature readings may vary from different locations on the

2. A child ‘s normal temperature can be as high as 9°F ( 37.7°C ) or as low as  97.0OF ( 36.1°C ). Please note that this unit reads 0.5°C (0.9°F) lower than a rectal digital thermometer.

3. 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
   ♦ been recently swimming or bathing
   In these cases, remove the individual from the situation and wait 20 minutes prior to taking a temperature. Use the untreated ear if prescription ear drops or other ear medications have been placed in the ear canal.

4. Holding the thermometer for too long in the hand before taking a measurement can cause the device to warm up. This means the measurement could be incorrect.

5. Patients and the thermometer should stay in steady-state room condition for at least 30 minutes.

6. Before placing the thermometer sensor onto the forehead, remove dirt, hair, or sweat from the forehead area. Wait 10 minutes after cleaning before taking measurement.

7. Use an alcohol swab to carefully clean the sensor and wait for 5 minutes before taking a measurement on another patient. Wiping the forehead with a warm or cool cloth may impact your reading. It is advised to wait 10 minutes before taking a reading.

8. In the following situations it is recommended that 3-5 measurements in the same location are taken and the highest one taken as the reading:
   • Newborn infants in the first 100 days.
   • 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.

Care and cleaning

Use an alcohol swab or cotton swab moistened with 70% alcohol to clean the thermometer casing and the measuring probe. After the alcohol has completely dried out, you can take a new measurement.
Ensure that no liquid enters the interior of the thermometer. Never use abrasive cleaning agents, thinners, or benzene for cleaning, and never immerse the instrument in water or other cleaning liquids. Take care not to scratch the surface of the LCD screen.
