6.Over temperature prompt function
Under the body temperature mode, if the measured body temperature is
higher than or equal to 38.0°C, the product will be vibrated for three times.
7.Changing the batteries
Display: when the LED screen displays the flashed symbol , the battery needs to change. Operation: Open the lid and change the batteries, taking great care with
the correct positioning. A mistake with this could cause damage to the apparatus and compromise the guarantee of your JXB-311. Never use rechargeable batteries.
Use only batteries for single usage.

XIV. Troubleshooting
If you have problems while using your thermometer, please refer to this guide to help resolve the problem. If the problem persists, please contact our customer service.
THE SCREEN DISPLAYS TEMPERATURE HIGHER THAN 43.0°C (109.4°F):
The temperature is in Fahrenheit. Change the measurement to Celsius.
THE SCREEN DISPLAYS TEMPERATURE LOWER THAN 32°C (89.6°F):
To take the surface temperature, press the “BODY” button and set to the reading called “Body” , If the device is in Surface Temp Mode, the 32°C
(89.6°F) temperature displayed is showing the external temperature of your body, rather than the internal.
THE SCREEN DISPLAYS THE MESSAGE HI
When using the JXB-311 Thermometer, the message “HI” can show on the screen. In this case,the temperature is above the measurement range selected, either above
43.0 °C (109.4°F) in Body Mode.
