The digital clock can be placed on a desk or mounted on a wall, making it suitable for bedrooms, kitchens, offices, living rooms, and more.
Helpful Tips
- Before first sync, select your local time zone.
- Place the clock near a window during setup for better WWVB signal reception.
- Sync time varies by location and signal conditions – be patient.
- Press the backlight button for 5-second illumination; this conserves battery life.
Does the clock adjust automatically for Daylight Saving Time?
Yes. When Auto DST is enabled, the clock automatically adjusts one hour forward or backward during Daylight Saving Time changes, so no manual reset is required.
How can I receive the atomic signal faster?
For best reception, place the clock near a window, away from metal objects and electronics. The signal is usually strongest at night, so leave it undisturbed overnight. Sync time varies by location and signal conditions.
What happens if the clock cannot receive the WWVB signal?
The clock will continue operating using its internal quartz movement and maintain normal timekeeping. It will automatically attempt to receive the atomic signal again later.
Does the clock have a backlight?
Yes. Press the SNOOZE/LIGHT button to activate the 5-second backlight for easy nighttime viewing.
Does the backlight stay on all the time?
No. The backlight is designed for quick nighttime viewing. Press the button to activate the light for 5 seconds, helping you check the time while conserving battery power. This design extends battery life significantly.
