5. Setup

5.1 Battery Installation

For the Remote Sensor:

1. Open the battery compartment cover on the back of the remote sensor.
2. Insert 2 x AA batteries (not included) according to the polarity markings (+/-).
3. Set the channel switch (1, 2, or 3) inside the battery compartment. Ensure each sensor uses a different channel if you have multiple.
4. Close the battery compartment cover. The LED indicator will flash once, indicating power.

For the Main Display Unit:

1. Open the battery compartment cover on the back of the main display unit.
2. Insert 3 x AAA batteries (not included) according to the polarity markings (+/-).
3. Close the battery compartment cover. The display will power on and begin searching for the remote sensor.

5.2 Sensor Placement

For optimal performance and accurate readings:

• Place the main display unit indoors, away from direct sunlight, heat sources, or vents.
• Position the remote sensor outdoors in a shaded, dry location, protected from direct rain and prolonged sun exposure. While the sensor has an IPX4 waterproof rating, protection from harsh elements will extend its lifespan and accuracy.
• Ensure the remote sensor is within the 330 ft (100m) transmission range of the main unit. Walls and other obstructions may reduce this range.

5.3 Synchronization

After installing batteries in both units, the main display unit will automatically attempt to connect with the remote sensor. The RF signal indicator on the display will flash during this process. Once connected, the outdoor temperature and humidity will appear on the display. If connection fails:

1. Press and hold the "CH" button on the main unit for 3 seconds to initiate a manual search.
2. Ensure the remote sensor is powered on and within range.
3. If still unsuccessful, remove and reinsert batteries in both units, starting with the remote sensor, then the main unit.

6. Operating Instructions
