Atomic Digital Alarm Clock for Home Use

The Sharp Atomic Wall Clock automatically synchronizes itself with the WWVB radio broadcast by the US Government's National Institute of Standards and Technology (NIST) in Fort Collins, Colorado, thanks to its built-in receiver. This ensures the Atomic Clock will always be accurate to within one second as it receives daily WWVB updates.

Featuring a bright color display, this digital wall clock can help you keep track of dates, days of the week, and times, making it ideal for the office, kitchen, or bedroom. The easy-to-read design makes it great for seniors or the elderly, with a simple setup and operation.

The Atomic Clock is packed with convenient features, including an indoor temperature display, calendar and day of week display, and a display nightlight with an on/off switch. The nightlight provides a low-light glow, making the display easy to read in the dark without being disruptive. However, note that the nightlight will not be visible in a well-lit room.

Powered by 3 AAA batteries (not included), the Sharp Atomic Clock can be wall-mounted or used on a tabletop or desk with its built-in stand. Measuring 6.45 inches by 5 inches, it is properly sized for bedside, desk, counter, or shelf use.

Atomic clocks work by automatically synchronizing with the WWVB radio signal broadcast daily by the US Government's National Institute of Standards and Technology in Fort Collins, Colorado. In most areas, this signal can only be received at night. If your clock does not immediately receive the WWVB signal, simply wait overnight, and it should be set by the morning. It may take up to 48 hours to fully synchronize.

While WWVB-controlled clocks generally work great, with hundreds of thousands sold across the US, there are a few troubleshooting tips that may help if you encounter issues:

• Mount the clock on a wall perpendicular to its current position (e.g., if it's on a north-south wall, try an east-west wall).
• Place the clock near a window facing Fort Collins or along a wall in that direction.
• Locate the clock at least 6 feet away from any computer monitors, which can cause interference.
• If nothing else works, take the clock outdoors at night, power it down, and then power it up again to force it to search for the WWVB signal. If it works outdoors but not indoors, you likely have a local interference problem.
• The shielding of a metal building, such as a mobile home or house with steel siding, may prevent the clock from receiving the signal.

Sharp has been the #1 alarm clock brand in America for over 25 years, with over 61 million units sold. Millions of people trust Sharp to help them start their day and stay on track.
