Atomic Clock with Indoor Outdoor Temperature - 8.5'' Digital Clock

The atomic clock quickly synchronizes with the WWVB radio broadcast to automatically update the time every midnight, ensuring accuracy. It supports 4 U.S. time zones: EST, CST, MST, and PST. This clock can display both indoor and outdoor temperatures, helping you manage your daily life more effectively. The wireless outdoor sensor, which should be placed within 330 feet and out of direct sunlight or rain, monitors and transmits the outdoor temperature to the clock.

Both the digital clock and outdoor sensor are battery-operated, requiring 3xAAA batteries for the clock and 2xAA batteries for the sensor (batteries not included). When the batteries are running low, a low battery symbol will appear on the screen and blink, reminding you to replace them.

The clock features a digital alarm and AUTO DST (Daylight Saving Time). When the alarm or DST is set, the corresponding icon will be displayed on the screen. Both can be manually turned off if not needed. With DST on, the clock will automatically adjust forward or backward by one hour during daylight saving time.

The large, easy-to-read display shows the time with seconds in the center, making it quick and simple to check the time. It also displays the indoor and outdoor temperatures, as well as the day and date, providing all the essential information you need at a glance.

The atomic clock offers two time modes: standard 12-hour time and military 24-hour time. When the clock time is set for one mode, the alarm time will automatically follow the same format. Additionally, the temperature display can be switched between Fahrenheit and Celsius by pressing the button on the back of the clock.

To get started, follow these simple steps:

1. Ensure the outdoor temperature link channel on the clock and outdoor sensor match (A-A, B-B, C-C).
2. Install the batteries (3xAAA for the clock, 2xAA for the outdoor sensor) and select your time zone.
3. The outdoor temperature will connect first, and then the clock will start searching for the WWVB signal.
4. Place the clock in a location with a good signal for better reception, and the outdoor sensor in a safe, shaded outdoor spot within 330 feet.
5. The clock will automatically update the time when the signal is successfully received.

Please note that in most areas, the WWVB signal can only be received at night. If your clock does not receive the signal during the day, wait until the next morning, and it will be set automatically. The outdoor temperature range is -40°F to 158°F (-40°C to 70°C), and the indoor temperature range is 32°F to 122°F (0°C to 50°C).
