Setup

1. Unpacking and Battery Installation

Carefully remove all components from the packaging. It is recommended to install batteries in the outdoor sensor first, then the display unit.

1. Outdoor Sensor: Open the battery compartment on the back of the wireless outdoor sensor. Insert 2 "AA" alkaline or lithium batteries (not included) according to the polarity markings (+/-). Close the battery compartment securely.
2. Display Unit: Open the battery compartment on the back of the digital display unit. Insert 3 "AAA" alkaline batteries (not included) according to the polarity markings (+/-). Close the battery compartment securely.

Note: Lithium batteries are recommended for outdoor sensors in regions with temperatures below -20°C (-4°F) due to their superior performance in cold conditions.

2. Sensor Placement

Proper placement of the outdoor sensor is crucial for accurate readings.

• Location: Choose a location that is out of direct sunlight and direct precipitation. A north-facing wall or under an eave is often ideal.
• Height: Mount the sensor approximately 1.2 to 2.4 meters (4 to 8 feet) off the ground.
• Obstructions: Ensure the sensor is away from heat sources (e.g., air conditioning units, exhaust vents) and large metal objects that could interfere with wireless transmission.
• Mounting: Use the integrated hanger to mount the sensor securely.

3. Display Unit Placement

The display unit can be placed on a tabletop or mounted on a wall.

• Tabletop: Use the integrated stand to place the unit on a flat surface.
• Wall-Mount: Use the keyhole slot on the back of the unit to hang it on a screw (not included) securely fastened to a wall.
• Wireless Range: Place the display unit within 330 feet (100 meters) of the outdoor sensor. Walls and other obstructions may reduce the effective range.

4. Synchronization

Once batteries are installed in both units, the display unit will automatically search for the outdoor sensor. This process may take a few minutes. Ensure both units are within range of each other. If the connection is not established, try relocating the sensor or display unit, or reset both units by removing and reinserting batteries.
