4. Setup

4.1 Powering the Units

1. Wireless Outdoor Sensor: Open the battery compartment on the back of the sensor. Insert 2x AA batteries, observing the correct polarity (+/-). Close the compartment.
2. Main Unit: Open the battery compartment on the back of the main unit. Insert 3x AAA batteries, observing the correct polarity (+/-). Close the compartment. For continuous display and backlight, connect the provided DC 5V power adapter to the power jack on the back of the main unit and plug it into a wall outlet.

4.2 Sensor Placement

Place the wireless outdoor sensor in a shaded, dry location away from direct sunlight and precipitation to ensure accurate readings. Ensure it is within the transmission range of the main unit (typically up to 60 meters in open air). Avoid placing it near large metal objects or electronic devices that could interfere with the signal.

4.3 Initial Synchronization

Once both units are powered on, the main unit will automatically search for and connect to the outdoor sensor. This may take a few minutes. The outdoor temperature and humidity readings will appear on the main unit's display once connected. If synchronization fails, ensure both units are within range and try re-inserting batteries in both units.

4.4 Setting Time and Date

Refer to the 'Operating Instructions' section for details on how to manually set the time, date, and other preferences using the control buttons.
