Product Information – Digital Atomic Wall Clock

The Digital Atomic Wall Clock (Model: W79752) is a highly accurate and reliable clock that automatically synchronizes with the atomic time signal. It also features an outdoor sensor (TX141) that provides temperature readings. The clock operates on 2-AA
batteries, while the outdoor sensor requires 2-AA batteries.

The clock displays atomic time at UTC 7:00, 8:00, 9:00, 10:00, and 11:00. It has a Settings Menu that allows you to adjust various settings, including time zone, language, daylight saving time (DST), and more. The clock also has an alarm function and displays
moon phases based on the lunar calendar.

If you encounter any issues with the clock or sensor, there are troubleshooting steps provided in the user manual. Additionally, you can contact our support staff for further assistance.
