To ensure proper use of the thermometer, please read this manual carefully before use.

To ensure safety and accuracy of the thermometer, it should only be repaired by a qualified professional using original replacement parts.

If the battery symbol on the LCD flashes, please replace the battery immediately to prevent inaccurate measurement.

Inspect the case before using the thermometer. Do not use the thermometer if it appears damaged. Look for cracks or missing plastic.

Avoid keeping the thermometer near high temperature environments for long periods.

To ensure measurement accuracy, please use the thermometer in the operating environment [15°C~30°C, <85% RH (non-condensing)].

Please use the thermometer indoors.

The ambient temperature of the measured object must be stable, and it should not be measured in places with large airflow such as fans and air outlets.

When changing to a new environment, please leave the thermometer for 30 minutes before use.

When the measured object comes from a place with a large temperature difference from the measurement environment, keep it in the measurement environment for 10 to 30 minutes before measuring.

Do not use the thermometer in places with strong sunlight or electromagnetic interference.

After measuring extremely high or low temperature objects, please leave the thermometer for 10 minutes before next use.

It is recommended to measure three times at a time, whichever is the most displayed set of data.

Make the sensor window directly face the measured object during measurement, otherwise it will cause the measured temperature to be different from the actual temperature.

3. When the measured temperature exceeds 37.2°C, the HI icon is displayed and the orange light gives an alarm.

In the HOLD interface, short press the SET button to enter the temperature unit setting interface, and switch between °C and °F by pressing the down button or up button.

In the HOLD interface, short press the SET button twice to enter the audible alarm setting interface, and turn on/off the audible alarm by pressing the down button or up button.

As the thermometer is reusable apparatus, please pay attention to cleaning and maintenance before use. If it is not in use for a long time, please keep its lens clean and dust free.

2. Clean the lens: Use clean compressed air to blow off loose particles. Carefully wipe the surface with a cotton swab dipped in medical alcohol or water.

If the thermometer is not in use for a long time, please remove the battery to prevent battery leakage. Dispose of used batteries properly in accordance with local regulations.

To replace the battery:

1. Open the battery cover.

2. Replace with a 9V battery (6F22), noting the polarity.

3. Close the battery cover.
