The Thermo works on two AAA (LR03) batteries and can operate for up to 2 years depending on the frequency of use.
Eventually you will need to change the batteries when the Thermo battery level gets low. To do so, follow these steps:
- Lift the magnetic cover of the battery compartment of your Thermo to open it.
- Remove the old batteries and dispose of them in accordance with local regulations.
- Place two new AAA (LR03) batteries in the compartment.
Make sure you follow the polarity markings when placing the batteries.
Note: Make sure you use alkaline batteries and not rechargeable batteries.
- Close the battery cover.
Note on removing the battery cover: To easily remove the battery cover from the Thermo, lightly press in on the cover near the top with your thumb. Then, slowly slide your thumb down to the bottom of the cover where it curves. As it presses against the curve of the battery case, it will slightly open the cover near the notch at the top. You will then be able to easily remove the cover by sliding your fingernail into the notch and pulling it out.
