Time is off by hours
Check to see if the WWVB
Tower icon appears on the clock. If not, the clock has
not received a WWVB time signal in the past 24-hours.
Reposition the 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 (most areas observe
DST so this should be ON). 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
Dependent 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 your 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. If the indicator is OFF the clock
will not change.
Check for fresh batteries. Without proper batteries, the antenna will have a
harder time picking up the signal.
Position the 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
