4.3 Emparellament de sensors
Once both the main unit and the sensor are powered, the main unit will automatically search for the wireless sensor. This may take a few minutes. Ensure the sensor is within range (up to 60 meters in an open area) of the main unit. If the outdoor readings do not appear, try the following:
- Press the "CH" button on the main unit to cycle through channels (if multiple sensors are used).
- Press the "RESET" button on both the main unit and the sensor, then re-insert batteries/power to initiate a new pairing process.
4.4 Col·locació
- Unitat principal: Place the main unit indoors on a flat surface using its built-in stand, or mount it on a wall. Avoid direct sunlight or heat sources.
- Sensor sense fils: Place the outdoor sensor in a shaded, dry location away from direct sunlight and rain to ensure accurate readings. Ensure it is within the wireless transmission range of the main unit.

- If using multiple outdoor sensors (up to 3 supported), ensure each is set to a different channel to avoid interference.
- The weather forecast function requires some time to calibrate to your local barometric pressure patterns. Allow 24-48 hours for it to become more accurate.
- When setting the alarm, remember to activate it using the ON/AL/OFF switch.
- The USB charging port is convenient for overnight charging of small devices, but note it is 5V, 1A, which may be slower than dedicated fast chargers.
