If you are getting the "HI" error message on your thermometer, it means that the target object temperature is higher than the thermometer's measurement range (43°C for body temperature mode or 93.2°C in object temperature mode).

If you are getting the "LO" error message on your thermometer, it means that the target object temperature is lower than the thermometer's measurement range (34°C for body temperature mode or 0°C in object temperature mode).

If this should not be happening (i.e. the temperature detected should be within a normal range for the target object), then please try the following steps to solve the issue:

  1. Make sure the device probe is clean.
  2. Make sure the device is within the suitable distance from the forehead or target object (3~5cm from the forehead)
  3. Then, take a new temperature
