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 (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
Some states are considering going to year around Daylight Saving Time. We have built in
options to accommodate this feature into the program menu.
DST ON: (Automatically gain 1 hour in spring, lose 1 hour in fall)
DST OFF: (Remain in Standard Time all year long)
DST ALWAYS ON: (Remain in Daylight Saving Time all year long)
•
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 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 .
