You can customize the settings for the NC° Thermometer Gen2 by going to the menu in the top-left corner of the app > My device > Device settings.
There, you can choose if you want the thermometer to beep, light up, or both when indicating that you should start and stop measuring. You need to have at least one of these options enabled at all times.
You can also change the units of measurement from Celsius to Fahrenheit (and vice versa).
Here you can also complete the Measuring Training to ensure you are measuring correctly and that your thermometer is working as it should. We always recommend completing the Measuring Training in the app when you first start using Natural Cycles.
We recommend reading the instructions listed in this article before completing the Measuring Training: When and how to do the Measuring Training with the NC° Thermometer Gen2
When you change a setting, you need to sync the app with the thermometer by pressing the Bluetooth button while on the My device page for the new setting to be applied.
On the My device page, you can also see your thermometer’s battery level, so you know when it needs to be changed. You can read more about how to do this here: How to change the battery on the NC° Thermometer Gen2.
