3.2 Remote Transmitter Sensors
The remote sensors transmit temperature and humidity data wirelessly to the main unit. Each sensor is designed for outdoor use and should be placed in a location protected from direct sunlight and rain. The system supports up to three remote sensors, allowing monitoring of different locations simultaneously.

4. Setup
4.1 Battery Installation
- Open the battery compartment on the back of both the main receiver unit and each remote sensor.
- Insert the provided AAA Batteries, ensuring correct polarity (+/-).
- Close the battery compartments securely.
4.2 Synchronization Process
After installing batteries, the main unit and remote sensors should automatically synchronize. The RF signal icon on the upper left of the main unit's display will flash during synchronization. If connection is lost or batteries are replaced, follow these steps:
- Ensure batteries are correctly installed in both units.
- Press the TX button on the remote sensor(s) to re-establish connection.
4.3 Placement Guidelines
- Main Unit: Place the main unit indoors on a tabletop using its built-in stand or mount it on a wall.
- Remote Sensors:
- Place sensors in an open area, avoiding wall obstructions.
- Keep sensors away from routers and other electronic devices to prevent high-frequency signal interference.
- Avoid direct sunlight exposure, as this can lead to inaccurate temperature readings.
- Always place sensors upright to prevent rain from entering through vent holes.
- The wireless range is up to 500ft/150m in open areas.
