6. Notes
6.1 Measurement
1. This product is only for monitoring and self-testing body temperature, can not be used for disease
diagnosis, patients only through the results of self-judgment and treatment is very dangerous, so please
follow the guidance of the doctor.
2. To ensure the accuracy of the measurement, please set the thermometer in the normal working
environment for more than 30 minutes, so that it reaches the equilibrium state before measuring.
3. Please do not measure under strong electromagnetic interference environment (working microwave
oven, induction cooker, mobile phone nearby, etc.), this may cause measurement is not correct or can not
be measured.
4. Participants were measured after taking medications that change their body temperature (e.g. aspirin,
acetaminophen, ibuprofen), which may cause measurement bias.
5. The subjects may cause temperature fluctuations after intense exercise, crying, eating, etc. It is
recommended to keep quiet for 30 minutes before measurement.
6. When measuring, please keep the subject quiet and steady, according to the measurement method
shown in the specification, so as not to cause the measurement deviation caused by improper operation.
7. Continuous measurement, the measurement results may have a small error, which is a normal
phenomenon, it is recommended that the maximum continuous measurement in a unit of time 3 times.
8. The human body temperature fluctuates from time to time, and the body temperature collected from
different parts will also vary. When observing the changes in body temperature, it is recommended to
measure and observe the body temperature in the same part multiple times.
9. Different types and brands of temperature measuring products do not have comparative value. It is
recommended to use the same temperature measuring product to observe temperature changes in order to
better grasp the temperature changes.

7. Installation and use
7.1 Installation of batteries
1.This product uses One CR1632 button battery and has been built into the thermometer body when it
leaves the factory.(Note: The built-in battery in the thermometer is a trial battery. This battery may not
provide the same life as the new battery.)

cover.
3.gently remove the battery cover, then take out the old battery.
4.Follow the battery polarity mark in the battery compartment and put the new battery into the battery
compartment. When installing, pay attention to the positive and negative polarity.
5.Reinstall the battery cover as is, and use a Phillips screwdriver to turn clockwise to tighten the fixing
screws.
7.2 Measurement process
7.2.1 Adjusted mode / Direct mode
1. Tap the “power key”, the thermometer will display in full screen, and then display the effective memory
temperature value measured last time.
2. If adjusted mode was used last time, then this measurement is also adjusted mode.
If direct mode was used last time, this measurement will also be in direct mode.
Note: In direct mode, the screen displays the " " direct mode icon.
3.When the icon "℃" or"℉" on the screen begins to blink, place the temperature sensor of the thermometer
