Problems and Solutions
The Display Does Not Indicate Temperature, but HI or LO
If the measured temperature is lower than 32°C or higher than 42.9°C, the LCD will display "LO" or "HI".
The Thermometer Does Not Turn On
- Check that the battery cover is properly closed.
- Place the batteries in a different position and try again.
The Thermometer Shows an Incorrect Value
- Check that the thermometer is in the correct mode. Change the mode by pressing the backlight button (3) for eight seconds.
- Check that the temperature unit is set correctly. Change the unit by holding the sound button (6) for eight seconds until the symbol on the LCD screen changes from °C to °F, or from °F to °C.
Reasons for 'LO' or 'HI' Notification and Solutions
| Reason for 'LO' or 'HI' Notification | Solution |
|---|---|
| The temperature value is affected by hair and sweat. | Make sure there are no obstacles when measuring the temperature. |
| The temperature is affected by airflow change. | Ensure stable air during temperature measurement. |
| The measuring distance is too far. | Make sure that the measuring distance is in the 5-10 cm range. |
