- Sensor Placement: Place the outdoor sensor in a location that is protected from direct sunlight and rain, but allows for good air circulation. Ensure it is within the 200ft/60m wireless transmission range of the main unit. Avoid placing it near large metal objects or other electronic devices that may cause interference.
- Pairing (if necessary): The sensor should automatically connect to the main unit upon power-up. If not, refer to the 'Troubleshooting' section or the specific pairing instructions in the full manual.

4.3 Initial Settings (Time, Date, Temperature Unit)
Upon first power-up or after battery replacement, you may need to set the time, date, and preferred temperature unit. Consult the full manual for detailed button functions. Generally:
