1. Advantages of the infrared thermometer
Dual-mode design (forehead temperature and ear temperature),you can
take body temperature by detecting the infrared ray given off by the
forehead or eardrum. The measuring range of the thermometer in
forehead /ear mode is between 32.0°F - 212.0°F (0 °C- 100 °C) .
The product consists of ABS plastics, temperature sensor, Infrared
temperature measuring element, microcomputer controlled circuit, LCD ,
backlight and buzzer.
Convenient for use
● Special ergonomic design to facilitate operation.
● No inconvenience would be caused to your daily life. It’s available for
measurement when your child is sleeping.
● It provides comfortable user experience compared with anal
thermometer for children, fast reading and simple operation compared
with mouth thermometer.
Memory recall
A maximum of 20 previous readings is available to help you track the
changes of your body temperature.
Safe and hygienic
● Compared to mercury thermometer, there is no danger of breaking the
glass or swallowing mercury.
● It is totally safe for children use.
Fever warning
When the reading exceeds 37.5℃/99.5℉, this product shall warn the
user that he/she may have a fever by 7 rapid and short beeps with LCD
flicker.(For normal forehead temperature, the signal is long beep with
LCD no flicker)
Extensive clinical data of hospital
The cooperation with designated hospitals is subjected to precise clinical
verification, with the support of extensive clinical data and professional
medical experts.
Application scope
The thermometer takes human body temperature for clinical or home use.
It applies to all age groups who are suffering from a fever.

2
Operating principle
The infrared temperature sensor detects infrared energy emitted by the
eardrum. A built-in lens focuses the collected energy, which is then
converted into a temperature reading by the thermopiles and
measurement circuits.
2. Necessary safety instructions
● Take care of the temperature probe lens, which is fragile.
● The device is not a continuous monitoring device.
● The device is not waterproof. Please do not douse it into water or
other liquids. Cleaning and disinfection procedure shall be in accordance
the instructions specified in [Cleaning and Disinfection]
● Do not try to repair the product if it is damaged. Please contact the
nearest Zewa Customer Service.
● The device consists of precision parts with high quality. Please
prevent the product falling off.
●Operating Conditions:

4.How to measure the forehead temperature
1. With the sensor/probe cover attached, position the thermometer at the
center of the forehead, just above the eyebrow, with a distance of 1-3cm.
2. Press and release the HEAD button.The temperature will be displayed
on the screen instantly.
5.How to measure the ear temperature
1. Gently remove the sensor/probe cover to reveal the ear probe.

2. Insert the ear probe into the ear canal.
3. Press and release the EAR button. The reading will be displayed on
the screen instantly.
Note:
Children under 1 year: Pull the ear straight back.
Children aged 1 year to adult: Pull the ear up and back.
In order to avoid the inaccuracy:
(1) Please make sure that there is no dirt on the temperature sensor
(2) Please make sure that the device only be used in room, and there is
no strongly conversation of wind.
(3) Before you measure the forehead temperature, there shall be no
water or any shade on the forehead.
(4) Before you measure the ear temperature, please clean the ear canal
first.
(5) Please make sure that there is no intense emotion and movement
before measuring.
(6) If thermometer is transferred from one condition to another which has
different ambient temperature, it is suggested to deposit for more than 30
minutes, and please follow the rule (2).
(7) If the user is transferred from one condition to another which has
different ambient temperature, it is suggested to have a rest for more
than 10 minutes, and please follow the rule (2).
(8) Do not hold thermometer for long time as it is highly sensitive to heat.
Connecting the thermometer to an APP
The thermometer has a built-in Bluetooth module and can be connected
to a smartphone by using the Bluetooth wireless technology. View the
measurement data in real time by using mobile phone software. The
software automatically saves the measurement which helps view the
temperature change in real time.
