# Default Settings

The Aranet4 is calibrated in the factory, and it works instantly when it you take it out of the box and insert the batteries – no additional setup is needed. These are the default settings of the Aranet4 device:

1. The default measurement interval is set to 5 minutes;
2. CO₂ sensor automatic calibration is disabled;
3. The default temperature measurement units are set to Celsius;
4. Bluetooth connection is enabled;
5. Bluetooth connection transmission range is set to normal;
6. The buzzer for audio sound alarm notifications is disabled;
7. CO₂ indication is set to human mode;
8. Access to Homey Smart Home assistant is enabled.

The 2nd, 3rd and 4th settings can be changed with the switches in the battery compartment on the back of the device for the Aranet4 screen, but the remaining five settings can only be changed via the Aranet Home phone application.
