3. Setup

3.1. Battery Installation

1. Main Unit (Clock): Open the battery compartment on the back of the clock. Insert 3 new AA batteries, ensuring correct polarity (+/-). Close the compartment.
2. Wireless Outdoor Sensor: Open the battery compartment on the back of the sensor. Insert 2 new AAA batteries, ensuring correct polarity (+/-). Close the compartment.

3.2. Sensor Pairing

To ensure successful pairing, power on the main unit (clock) first, then the sensor, within 3 minutes of each other. The clock will automatically search for the sensor signal.

5. Maintenance

5.1. Battery Replacement

When the battery low indicator appears on the display, replace the batteries in both the main unit and the outdoor sensor with new ones. Always replace all batteries at the same time to ensure optimal performance.

5.2. Cleaning

Wipe the clock and sensor surfaces with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the display or casing.

5.3. Wireless Sensor Placement

For accurate outdoor temperature readings, place the wireless sensor in a shaded, dry location, protected from direct sunlight and rain. Ensure it is within the 330-foot (100-meter) range of the main clock unit and away from large metal objects or other sources of interference.

6. Troubleshooting

6.1. No Outdoor Temperature Reading

• Ensure batteries in both the main unit and sensor are fresh and correctly installed.
• Verify the sensor is within range (330 feet/100 meters) of the main unit.
• Relocate the sensor or main unit to minimize interference from other electronic devices or large metal structures.
• Re-pair the sensor by removing and reinserting batteries in both units, powering the main unit first.

6.2. Atomic Time Synchronization Failure

• Ensure the clock is placed in an area with good reception, ideally near a window and away from electronic devices that may cause interference.
• Check that the correct time zone is selected.
• Manual time adjustment is possible if atomic synchronization is consistently unsuccessful. Refer to the 'SET' button instructions on the back of the clock.

6.3. Display Issues (e.g., dim, incomplete segments)

• Replace the batteries in the main unit.
• Ensure the clock is operating within its specified temperature range.
