WWVB Atomic Time Signal
For information about WWVB, visit:
www.nist.gov/pml/div688/grp40/wwvb.cfm
Daylight Saving Time:
The National Institute of Standards and Technology and WWVB
encode a special DST “bit” in the WWVB transmission for DST.
Your clock will read this information and automatically advance the
hands one hour in the spring and eleven hours in the fall.
Arizona
• If you live in an area that does not recognize DST, you must
slide the DST switch OFF.
• To reactivate the DST program simply slide the switch to the
ON position.
Q-Mode-Manual Set Time
On rare occasions, the clock may not be able to receive Atomic
time because of the strength of the signal or the geographic
location. In this case, the clock can be set manually and used as
a regular Quartz wall clock.
1. Set DST switch to the OFF (Q-Set).
2. Set Time Zone switch to the Q-MODE.
Note: The movement will move to 4 o’clock 8 o’clock or 12
o’clock position and stop.
