Atomic Clock with Outdoor and Indoor Temperature - 12.5 Inch Digital Clock for Bedroom, Living Room, Office

As a Radio Controlled Atomic Clock, this device can receive the time signal transmitted by the National Institute of Standards and Technology (NIST), which is regulated by 3 atomic clocks and deviates less than 1 second within 3,000 years. The NIST broadcasts the time signal (WWVB, 60kHz) continuously from Fort Collins, Colorado, and this signal can be received anywhere in the continental USA and Canada where long-wave (AM) radio reception is possible using a portable radio. The signal is expected to reach a distance of over 2,000 miles from the transmitter.

Consequently, the clock will receive the signal within the broadcast range wherever an AM signal can be picked up. However, the time signal may not be received in massive metal and concrete structures unless near a window. Additionally, some environmental effects may influence the transmitting distance and reception.

This digital wall clock will automatically receive the time signal every day at midnight and make any necessary adjustments to the time setting, making it more accurate than ordinary electronic clocks. Therefore, it is highly suitable for those with strict requirements for time accuracy, such as scientists, stock traders, doctors, nurses, teachers, and lawyers.

It is important to note that frequent use of the self-setting feature may affect battery life. If the clock fails to receive the signal within 48 hours or if you encounter any problems, please contact the manufacturer for assistance.

The indoor temperature monitoring of this digital clock is based on a built-in Swiss high-precision SHTC3 sensor, while the outdoor temperature monitoring is achieved through a radio frequency (RF) transmitter that collects and sends the outdoor temperature information to the receiver, which then displays the temperature on the clock. The maximum receiving distance for the outdoor temperature is 330ft.

The operating temperature range for this clock is from -40°F to 158°F (-40°C to 70°C). The indoor temperature display range is also -40°F to 158°F (-40°C to 70°C), with measurements taken every 10 seconds. The outdoor temperature display range is the same, with the transmitter measuring the temperature every 10 seconds and transmitting the RF signal every 32 seconds.

To ensure the successful reception of the WWVB time signal, it is recommended to place the clock in an open area or near a window with good signal, and to avoid placing it near iron household items. The clock's default settings include auto daylight saving time, 12-hour time format, and the Eastern time zone. If you need to change these settings, do so before the clock starts searching for the RCC time signal.

Finally, this digital clock makes a great gift idea for various occasions, such as Thanksgiving, Christmas, Halloween, birthdays, and weddings, thanks to its beautiful packaging, appealing design, and excellent features.
