Important: When batteries are installed, the hands will move to
4 o’clock, 8 o’clock, or 12 o’clock position and search for the
Atomic Time signal.
•If successful, the hands will move to the time received for the
time-zone selected.
•If not successful, the hands will stay either at 4 o’clock 8
o’clock or 12 and the movement will continuously keep trying
to receive the Atomic Time.
Position Clock
•For the best reception, please place clock on a wall that faces
Ft. Collins, Colorado.
•Signal reception is at its peak when there is only one wall or
window between the clock and the outside.
•The antenna is best positioned for signal reception when the
front or back of the clock faces Colorado.
•Choose a location six feet or more from electronics such as
cordless phones, wireless gaming systems, televisions,
microwaves, routers, baby monitors, etc., which can prevent
signal reception.
•Large office buildings, schools, or hospitals may not receive
the WWVB time signal in every room.
•Metal roofs on buildings may interfere with reception.
Note: We recommend that you change the batteries every 24
months to maintain accuracy. Remove the battery when the clock
will not be in use for an extended period.

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.

Troubleshooting
The wonderful advantage of owning an UltrAtomic clock is that it is
virtually trouble free. When the clock receives a clear atomic time
signal, it will set itself perfectly. If it does not receive an atomic
time signal, consider the following:
•Batteries – The clock must have a fresh batteries to receive
and process the time signal. Low batteries are indicated when
the Hour and Minutes hands run as usual but the second hand
stops at the 6.
•Location – Try a different location, ideally near a window. Your
clock should be at least six feet from computers, TVs, air
conditioners, other atomic clocks and other electrical
appliances that cause interference.
•Weather – Electrical storms between you and Colorado during
the night will interfere with the WWVB signal.
