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

Accurate Atomic Clock - This atomic clock features a built-in receiver that automatically synchronizes with the WWVB radio broadcast, ensuring accurate time updates every midnight. It supports 4 U.S. time zones: EST, CST, MST, and PST.

Atomic Clock with Indoor and Outdoor Temperature - The atomic clock can display both indoor and outdoor temperatures, helping you better manage your daily life. The wireless outdoor sensor monitors and transmits the outdoor temperature to the clock, which should be placed within 330 feet and out of direct sunlight or rain.

Digital Clock Battery Operated (No Backlight) - Both the digital clock and outdoor sensor are powered by non-rechargeable batteries: 3xAAA for the clock and 2xAA for the outdoor sensor (batteries not included). When the batteries run low, a low battery indicator will appear on the screen, reminding you to replace them.

Digital Alarm Clock with AUTO DST - The clock features a digital alarm with a corresponding icon on the screen. Both the alarm and daylight saving time (DST) can be manually turned on or off as needed. With DST enabled, the clock will automatically adjust forward or backward by one hour during daylight saving time.

Large Display with Temperature, Day, and Date - The clock displays the time with seconds in large, bold numbers in the middle of the screen, making it easy to read. It also shows the indoor temperature, outdoor temperature, day, and date at the bottom, providing all the essential information you need.

12/24Hr Time Mode and Fahrenheit/Degree Switchable - This atomic clock has two display modes: standard time (12-hour) and military time (24-hour). 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.

Quick Setup Instructions: 1. Match the outdoor temperature link channel of the clock and outdoor sensor (e.g., A-A, B-B, C-C). 2. Install 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 good signal reception and the outdoor sensor in a safe, shaded outdoor spot 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 the clock does not receive the signal during the day, wait until the next morning for it to be set. - 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 out of direct sunlight and rain for longer service life.
