Supported Time Zones

This clock has 7 Time Zones: AST = Atlantic, EST =Eastern, CST =Central, MST =Mountain, PST = Pacific, AKT = Alaska & HAT = Hawaii
The digital clock works in North America.

When operating on batteries only, the backlight will come on briefly when the SNOOZE button is pressed.

Time is off by hours

Check to see if the WWVB Tower icon appears on the atomic digital clock. If not, the digital clock has not received a WWVB time signal in the past 24 hours.
Reposition the digital clock with the front or back facing Colorado.
Check that the Time Zone selected correctly reflects your location. Adjust the time zone in the Program Menu.
Check that the DST indicator is correct for your location (On this clock, please change the DST setting to OFF unless you live in Arizona). Adjust the DST indicator in the Program Menu.
Large buildings, metal roofed buildings and buildings or rooms full of electrical and/or radio equipment make it difficult to receive the WWVB time signal.

Daylight Saving Time

Depending on your location, position of the clock in your home, and atmospheric interference, it may take up to 5 nights for the change from Daylight Savings Time to Standard Time and vice versa to occur.
Check for a WWVB Tower Icon showing on the atomic digital clock. The tower icon indicates you have received the WWVB signal from Ft Collins CO in the past 24 hours.
Check that the clock is in the correct Time Zone.
Check whether the DST indicator is ON or OFF. On this clock, please change the DST setting to OFF unless you live in Arizona.
Check for fresh batteries. Without proper batteries, the antenna will have a harder time picking up the signal. Position the digital clock in a window (with the front or back ) facing Ft. Collins, Colorado, and leave for up to five nights. If you do not have a window facing this direction, position the clock near an outside wall and point the unit in this general direction.
