PRODUCT DESCRIPTION

Introduction

Dr Trust Homedoc Ear and Forehead Thermometer is a dual temperature mode (Â°F / Â°C) thermometer. It measures the body temperature based on detecting 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 on the forehead. The operation of this thermometer is very simple. It can be operated through a power button that is present on the top of the device just below the large size LED screen. The LED screen displays measurements in large size digits which are easy to read even in dark conditions. Also, there are 3 colour codes to indicate diﬀerent temperatures of fever.

Note:

At the end of the temperature measurement, the buzzer gives a ‘beep’ cue.
Ear temperature measurement can only be applied to people who are over 3 months old.

Normal Body Temperature Range

Normal body temperature has a range. The following table shows that this normal range also varies by measuring diﬀerent sites. Therefore, readings from diﬀerent site should not be directly compared. Tell your doctor what type of thermometer you have used and what part of body you have measured. Also keep this in mind if you are diagnosing yourself.

Intended Use

The multifunctional infrared thermometer is intended for measuring the human body temperature, it has two measurement modes;
The forehead mode: Indicated for people of all ages.
The ear mode: Indicated for people above three months old.

WORKING PRINCIPLE

The Dr Trust Homedoc Ear and Forehead Thermometer is intended for the measurement of human body temperature. Its sensor collects infrared energy emitted by the eardrum in the ear canal or the skin of the forehead. After being focused by a lens, the infrared energy is converted into a temperature reading by the thermopiles and measurement circuits.

Note:
The forehead mode is indicated for people of all ages and the eardrum mode is indicated for people above three months old.

Caution
Do not use the thermometer if the ear is infected with otitis or suppuration.

Do not force the thermometer into the ear canal. Otherwise, the ear canal may get injured.
Children aged 1 year to adult: Pull the ear up and back.
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.

Note

The normal ear temperature range is approximately between 35.5 °C and 37.7 °C.
Please make sure that the ear is clean, with no earwax or obstructions. Insert the probe straight into the ear canal.
The right ear reading may diﬀer from the reading taken at the left ear. Therefore, always take the temperature in the same ear.
It is important to point the probe lens of the ear thermometer toward the eardrum and its periphery inside the ear.
To straighten the ear canal, gently pull on the outer ear in the direction of the rear of the head.
Each ear canal has a slightly diﬀerent shape, be sure to check it before taking temperature readings.

Set Threshold for Low Fever

This thermometer has preset 37.5℃/99.5℉ as an alarm temperature for low fever. However, 37.5℃/99.5℉ is only a reference value. At this temperature, diﬀerent people feel diﬀerent, some feel uncomfortable, but others feel ne. If you don’t agree with this low fever threshold, you can manually change it to suit your own situation after consulting your doctor.

In the state of shutdown, hold pressing the Setting button for 12 seconds until you see the orange status light on the screen, release the button. (Note: Ignore the other symbols that appear in the process).
Keep pressing the Set button to increase the threshold (every time 0.1℃/0.2℉ threshold will increase). The adjustment range is from 37.5℃/99.5℉ to 37.9℃/100.2℉.
Once it reaches the Max. value, press the button again, it will go back to the Min. value, then repeat the cycle.
After setting, press the button for about 5 seconds, the thermometer will shut down and save the setting automatically.

Set Threshold for High Fever

This thermometer has preset 38.0℃/100.4℉ as an alarm temperature for high fever. However, 38.0℃/100.4℉ is only a classic reference value.
At this temperature, diﬀerent people feel diﬀerent, some feel bad, but others feel not too bad. If you don’t agree with this high fever threshold, you can manually change it to suit your own situation after consulting your doctor.

Turn oﬀ

When the thermometer is turned on, the thermometer will shut down automatically after it is not used for 30 seconds. You can hold down the Power button for 5 seconds to shut down the thermometer manually.

Mount two new AAA batteries into the battery bin according to the marked polarity symbols.
Close the battery cover, the thermometer can be restored to normal use.

Caution
Take out the batteries if the thermometer will not be used for more than one month.

TIPS TO MAKE CORRECT TEMPERATURE MEASUREMENTS

It is important to know everyone’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 forehead.
A child’s normal temperature can be as high as 99.9°F (37.7)ºC or as low as 97.0°F (36.1)ºC. Please note that this unit reads 0.5ºC (0.9°F) lower than a rectal digital thermometer.
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.
Patients and the thermometer should stay in steady-state room condition for at least 30 minutes.
Before placing the thermometer sensor onto the forehead, remove dirt, hair, or sweat from the forehead area.
Wiping the forehead with a warm or cool cloth may impact your reading. It is advised to wait 10 minutes before taking a reading.
Use an alcohol swab to carefully clean the sensor and wait for 5 minutes before taking a measurement on another patient.

MULTI MEASUREMENTS REQUIREMENTS

In the following situations 3-5 measurements recommended to be taken in the same location. The highest one is the standard 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.

KEY FACTORS THAT INFLUENCE EAR TEMPERATURE READINGS

Some external factors that may influence ear temperature, include:

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

Cautions

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

MAINTENANCE AND CARE

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 LED screen.
Keep water oﬀ the infrared sensor lens during the cleaning process. Otherwise, the lens may be damaged.
The infrared sensor lens may be scratched if it is cleaned with a piece of tissue paper, resulting in inaccurate readings.
