2. PRODUCT DESCRIPTION
1) Overview
The Dr Trust Handy Forehead and Ear Thermometer- 607 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 on forehead.
Normal body temperature is a range. The following tables shows that this normal range also
varies by site. Therefore, readings from different site 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.

Measurements
Forehead temperature 36.1°C to 37.5°C (97°F to 99.5°F)
Ear temperature 35.8°C to 38°C (96.4°F to 100.4°F)
Oral temperature 35.5°C to 37.5°C (95.9°F to 99.5°F)
Rectal temperature 36.6°C to 38°C (97.9°F to 100.4°F)

2) Structure
The thermometer consists of a shell, an LCD, an operation button, an infrared
temperature sensor, a microprocessor and a beeper.
3) Operating principle
The infrared temperature sensor collects infrared energy emitted by the eardrum or the
skin surface. The collected energy is converted into a temperature reading by the
thermopiles and measurement circuits.
4) Indications for use
The Dual-mode Infrared Thermometer is intended for the measurement of human body
temperatures. The forehead mode is indicated for people of all ages and the eardrum mode
is indicated for people above three months.
Note
Do not use the thermometer if the ear is infected with otitis or suppuration.

The Dr Trust Handy Forehead and Ear Thermometer- 607 is lightweight, gentle and easy
to use device. It comes with all the things needed to get a thorough reading. When using
the thermometer for the rst time, please check the batteries and press the Measure
button to check it is ready for use.
ŸRelease the buon when a beep is heard.
1. Forehead Temperature Measurement

NOTE
ŸThe normal temperature range on the forehead is approximately between 35.4 °C
and 37.4 °C.
ŸIf the eyebrow area is covered with hair, sweat or dirt, please clean the area
beforehand to improve the reading accuracy.
ŸThe forehead measurement is an indicative reading. The measured forehead
temperature can uctuate up to 1 ºF/0.5 ºC from your actual body temperature.
Please be aware of the factors that inuence the accuracy as described in the
section “Temperature taking tips” and “WARNINGS AND PRECAUTIONS”.
ŸAlways make sure the user and the thermometer will have been in the same room
for at least 30 minutes prior to the measurement.
ŸAlways check if the lens is clean.
2. Ear Temperature Measurement
The temperature of the eardrum can be measured easily with this thermometer.
ŸTake off the probe cover
ŸInsert the probe into the ear canal to get the result in 1 second.
ŸPress the Measure button and release it in 1 second when the beep is heard.
ŸThe body temperature is shown on the LCD display.
Safety Measures
üChildren under 1 year: Pull the ear straight back.
üWhen 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.
üBe careful when taking temperature on a child, whose ear canal is small.
üChildren aged 1 year to adult: Pull the ear up and back.
üDo not force the thermometer into the ear canal. Otherwise, the ear canal may get
injured.
Note
ŸInsert the probe straight into the ear canal.
ŸPlease make sure that the ear is clean, with no earwax or obstructions.
ŸThe normal ear temperature range is approximately between 35.5 °C and 37.7 °C.
ŸTo straighten the ear canal, gently pull on the outer ear in the direction of the rear of
the head.
ŸIt is important to point the probe lens of the ear thermometer toward the eardrum
and its periphery inside the ear.
ŸEach ear canal has a slightly different shape, be sure to check it before taking
temperature readings.
ŸThe right ear reading may differ from the reading taken at the left ear. Therefore,
always take the temperature in the same ear.
3. Room/object Temperature Measurement
When the thermometer is power off, press the Memory/baby button for 5 seconds until it
shows on display.
ŸPress and release the measure button to start the object temperature
measurements.
ŸThe LCD display shows the results for object temperature value.
ŸKeep the thermometer about 1-5cm away from the object.
ŸPress and release the Measure button in 1 second with a beep sound.

1312
Note:
ŸMeasures surface temperatures and not the internal temperature of objects or items
like food etc.
ŸNeeds adjustments depending on your requirements.
ŸMeasurements can be affected by moisture, dust, smoke or other particles in the air.
4. Switch to Baby mode
Press the Memory/baby button when power on. Then it will switch to baby mode. Baby
mode is suitable for baby aged from 0-36 month.
After A Temperature Measurement
ŸOnce the temperature measurement has been completed, remove the thermometer
away from the forehead/ear and observe temperature.
ŸAfter each measurement, you can enter the recall mode to check the earlier
temperature readings.
ŸNote
ŸPlease wait for 10 seconds between each measurement.
ŸDo not hold the thermometer for a long time, because it is sensitive to the ambient
temperature.
ŸAfter each measurement, clean the temperature probe with a soft cloth, and put the
thermometer in a dry and well-ventilated place.
IMPORTANT
It is dangerous to make a self-diagnosis or self-treatment based on the obtained
measurement results. For such purposes, please consult a doctor.

7. TIPS TO MAKE CORRECT TEMPERATURE MEASUREMENTS
ŸIt is important to know everyone’s normal temperature when they are well. This is
the only way to accurately diagnose a fever.
ŸRecord readings twice a day (early morning and late afternoon). Take the average of
the two temperatures to calculate normal oral equivalent temperature.
ŸAlways take the temperature in the same location, since the temperature readings
may vary from different locations on the forehead.
ŸHolding 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.
ŸPatients and the thermometer should stay in steady-state room condition for at least
30 minutes.
ŸA child’s normal temperature can be as high as 99.9°F (37.7) or as low as 97.0°F
(36.11). Please note that this unit reads 0.5ºC (0.9°F) lower than a rectal digital
thermometer.
ŸBefore placing the thermometer sensor onto the forehead, remove dirt, hair, or
sweat from the forehead area.
ŸWiping the forehead with a warm or cool cloth may impact your reading. It is advised
to wait 10 minutes before taking a reading.
ŸUse an alcohol swab to carefully clean the sensor and wait for 5 minutes before
taking a measurement on another patient.
8. MULTI MEASUREMENTS REQUIREMENTS
ŸNewborn infants in the rst 100 days.
ŸWhen the user is learning how to use the thermometer for the rst time until he/she
has familiarized himself/herself with the instrument and obtains consistent readings.
ŸChildren under three years of age with a compromised immune system and for
whom the presence or absence of fever is critical.
In the following situations 3-5 measurements recommended to be taken in the same
location. The highest one is the standard reading.
9. KEY FACTORS THAT INFLUENCE EAR TEMPERATURE READINGS
Some external factors that may inuence ear temperature, include:
Ÿbeen exposed to very hot or very cold temperatures, or
Ÿbeen recently swimming or bathing
Ÿbeen lying on one ear or the other
Ÿhad their ears covered

1716
Cautions
ŸUse the untreated ear if prescription ear drops or other ear medications have been
placed in the ear canal.
ŸIn these cases, remove the individual from the situation and wait 20 minutes prior to
taking a temperature reading.
10. CARE AND MAINTENANCE
ŸUse 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.
