Question about Home
I am constantly getting a LO reading. No temp being displayed. Batteries have been changed
It's probable that it needs a new lens filter or the filter needs cleaning. I have no idea how to remove the filter but it probably clips or screws off the bit that goes in the ear.
Quite frankly the device is at best unreliable, it measures infra-red in the ear, great in theory but not very reliable in practice. I would use a different thermometer.

Ambient temperature is not within the allowed operating range (10 - 40 °C or 50 - 104 °F).
Allow the thermometer to remain for 30 minutes in a room where the temperature is
between 10 and 40 °C or 50 and 104 °F.
Here is a link to the manual if you should need it:

If you whish to switch from Celsius to Fahrenheit, proceed as follows:
(1) Make sure the thermometer is turned off.
(2) Press and hold down the Start button (IRT 4020)
or the «I/O» button (IRT 4520). After about
3 seconds the display will show this sequence:
«°F» / «SET» / «°C» / «SET» ...
(3) Release the Start button / «I/O» button when the
desired temperature scale is shown. There will be
a short beep to confirm the new setting, then the
thermometer is turned off automatically.
