1. Open the battery compartment on the back of the outdoor sensor.
2. Insert 2 x AAA batteries (not included), ensuring correct polarity.
3. Select a channel (1, 2, or 3) using the switch inside the battery compartment. If using only one sensor, select Channel 1.
4. Press the 'TX' button to transmit the signal.
5. Close the battery compartment.

2.3 Pairing the Sensor with the Main Unit:

1. Ensure both the main unit and the outdoor sensor are powered on.
2. The main unit will automatically search for the sensor signal. The outdoor temperature and humidity should appear on the display within a few minutes.
3. If the outdoor readings do not appear, press and hold the 'DOWN' button (with the Wi-Fi symbol) on the back of the main unit for 3 seconds to initiate a manual search.
