Atomic Clock with Indoor Outdoor Temperature - 8.5'' Digital Clock Battery Operated, Self-Setting, 4 Time Zones, DST

The atomic clock has a built-in receiver that automatically synchronizes itself with the WWVB radio broadcast, ensuring accurate time updates every midnight across 4 time zones: EST, CST, MST, PST. This atomic clock can display both indoor and outdoor temperature, helping you better manage your daily life. The wireless outdoor sensor monitors and transmits the outdoor temperature to the clock for display, with the sensor placed within 330 feet and out of direct sunlight or rain.

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

The digital alarm clock features AUTO DST, with corresponding icons displayed when the alarm or daylight saving time is set. Both can be manually turned off if not needed. With DST on, the clock will automatically adjust forward or back by one hour during daylight saving time changes.

The large display shows the time with seconds in bold in the middle, making it easy and quick to read. It also presents indoor/outdoor temperature, day, and date at the bottom, providing all the essential information you need on the clock.

This atomic clock offers two display 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. Additionally, the temperature display can be switched between Fahrenheit and Celsius by clicking the button on the back.

To get started, follow these steps:

1. Adjust the outdoor temperature link channel of the clock and outdoor sensor to be the same, such as A-A, B-B, C-C.
2. Install the batteries and choose your time zone.
3. The outdoor temperature will connect first, and once finished, the clock will start searching for the WWVB signal.
4. Place the clock in a location with good signal reception, and the outdoor sensor in a safe place outside within 330 feet/100m.
5. The clock will automatically update the time once the signal is successfully received.

Tips: - 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 overnight, and it will be set in the morning. - 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). - The outdoor sensor should be placed within 300ft/100m and out of direct sunlight or rain for longer service life.
