4. Setup
4.1 Battery Installation
The digital display unit requires 2 AA batteries, and the wireless outdoor sensor requires 2 AA batteries (not included). For optimal performance, use high-quality alkaline or lithium batteries.
- Display Unit: Open the battery compartment cover on the back of the display unit. Insert 2 AA batteries, observing the polarity markings (+/-). Replace the cover.
- Wireless Sensor: Open the battery compartment cover on the back of the sensor. Insert 2 AA batteries, observing the polarity markings (+/-). Replace the cover.
Note: It is recommended to install batteries in the outdoor sensor first, then in the display unit, to ensure proper synchronization.
4.2 Sensor Placement
Proper placement of the wireless sensor is crucial for accurate temperature readings and optimal signal transmission.
- Place the sensor outdoors, away from direct sunlight and heat sources (e.g., exhaust vents, windows).
- Ensure the sensor is protected from direct precipitation. An ideal location is under an eave or a covered porch.
- Mount the sensor vertically using the integrated hanger or a screw (not included).
- The maximum wireless range is 165 feet (50 meters). Consider obstacles like thick walls, metal siding, or large electronic devices that may interfere with the signal.

4.3 Display Unit Placement
The display unit can be placed on a flat surface using its integrated stand or mounted on a wall using the keyhole hanger.
- Choose a location indoors that is easily visible and within range of the outdoor sensor.
- Avoid placing the display near windows or vents that could affect its indoor temperature reading.
5. Operation
5.1 Reading the Display
