Atomic Clock with Indoor Outdoor Temperature

The WallarGe atomic clock receives the WWVB radio broadcast every midnight to keep time accurate without manual adjustment. It displays indoor and outdoor readings on an 8.5 inch carbon black digital screen. Four North American time zones are selectable and daylight saving changes apply automatically when enabled.

Battery Operated Installation and Sensor Pairing

Both units run on standard non-rechargeable cells: three AAA for the clock and two AA for the wireless sensor, none of which are included. The sensor must be set to the same ABC channel as the clock and placed within 330 feet, away from direct sun and rain. A blinking low-battery icon appears on the display when power is running low.

Continuous Operation Without Backlight

The clock has no backlight, so the display remains readable in ambient light but dark at night. Time, date, alarm status and temperature units stay visible as long as batteries hold charge. Automatic WWVB synchronization corrects any drift each midnight, and the outdoor sensor continues transmitting temperature data as long as the channel match is maintained.

Questions about this item

How do I confirm the WWVB atomic sync is working after I install the batteries?

The clock will display the correct time and show a reception icon once it locks to the WWVB signal, which it attempts every midnight.

What comes in the box and which batteries must I buy separately?

The box contains the 7.0 x 1.5 x 5.2 in carbon black clock and one wireless outdoor sensor; you must supply 3xAAA for the clock and 2xAA for the sensor.

Should I choose the 12-hour or 24-hour display mode for my needs?

Press and hold the TIME SET button to toggle between standard 12-hour and military 24-hour formats; both show indoor and outdoor temperature in the same °F or °C setting.
