4. Setup
4.1 Main Unit Setup
- Power Supply:
- Insert 3x AA batteries (not included) into the battery compartment, observing correct polarity.
- Alternatively, connect the provided USB charging cable to the main unit and a power source. If both are connected, the USB power will be prioritized.
- The main unit will power on and display indoor temperature and humidity.
4.2 Remote Sensor Setup
- Insert 2x AAA batteries (not included) into each remote sensor, observing correct polarity.
- The sensors will automatically attempt to pair with the main unit. The main unit will display the readings from each connected sensor on channels 1, 2, and 3.
- If a sensor does not connect, press the "RF SEARCH CHANNEL" button on the main unit to initiate a search. Ensure sensors are within range.
- Place the remote sensors in desired locations (e.g., outdoors, in a greenhouse, or another room). Avoid placing them in direct sunlight or areas with poor ventilation, as this can affect measurement accuracy.

9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit. | Batteries are dead or incorrectly inserted; USB cable not connected or faulty. | Check battery polarity and replace if necessary. Ensure USB cable is securely connected to a working power source. |
| Remote sensor not displaying data. | Sensor batteries are dead; sensor is out of range; interference; sensor not paired. | Replace sensor batteries. Move sensor closer to the main unit. Press "RF SEARCH CHANNEL" on the main unit to re-pair. Avoid strong electromagnetic interference. |
| Inaccurate readings. | Sensor placed in direct sunlight, near heat/cold sources, or in poor ventilation. | Relocate sensors to a shaded, well-ventilated area away from extreme temperature sources. Allow time for readings to stabilize after relocation. |
| Backlight not working or dim. | Battery power only; low battery. | Connect via USB for brighter backlight options. Replace main unit batteries if backlight is dim on battery power. |
