14” ULTRATOMIC WALL CLOCK
Thank you for purchasing the first and only clock in the market
that receives the NIST’s newly enhanced phase-modulation based
broadcast. The broadcast is based on a dual-antenna scheme,
making it insensitive to the orientation of installation. This clock is
designed for significantly better signal reception.
With optional custom settings, you are able to view times from
different time zones (+0 UTC to -11 UTC).
Use two or four
“C” batteries

Get Started - Atomic Time
1: Slide the time zone switch to your time zone.
PT = Pacific, MT = Mountain, CT = Central, ET = Eastern
2: Select DST (Daylight Saving Time) setting ON/OFF.
When ON is selected, the clock will automatically adjust for
DST (most common).
3: Insert two or four fresh “C”, LR14 1.5 volt batteries according to
the polarity markings.
Important: When batteries are installed, the hands will move to
4 o’clock, 8 o’clock, or 12 o’clock position and the clock will start
receiving the Atomic Time signal from Colorado. When signal is
received, the hands will move to the correct time for the selected
time zone.
Optional Settings
Atomic Time with Custom Time Zone Selection
This clock allows you to select more than the
four major North American time zones by using
the CUSTOM ET setting.
1. Slide the Time Zone switch to CUSTOM ET.
2. Press and release the SET button to
advance the time in one hour increments.
3. The clock will keep time in the new time
zone selected.Time Zones available (+0 UTC to -11 UTC)
Daylight Saving Time:
The new WWVB broadcast provided by the National Institute of
Standards and Technology includes a notification for the daylight
saving transitions well ahead of when they are to occur. The
UltrAtomic clock reads this information, and at the appropriate
instances, automatically advances the hands one hour in the
spring and eleven hours in the fall (to move back one hour), even
if the signal is not received on the day of the transition.

Q-Mode - Manual Set Time
The clock can be set manually and used as a regular Quartz wall
clock even in areas that are beyond the range of the WWVB
broadcast, such as in Asia. It may also be helpful to set the clock
manually if one does not wish to wait for it to receive the signal
from the broadcast, which in some cases would only occur at
night.
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.
3. Hold the SET button to set the time quickly.
4. Press and release the SET button to change the time slowly.
5. When time is set, slide the DST switch to ON (Q-RUN)
position.
6. The second hand will start running from 12:00 and the clock
will keep time as manually set.

ECO-Mode
Eco-mode is a battery saving feature that stops the second hand
at 12:00, between the hours of 11pm-5am.
Eco Mode switch ON: Second hand does not
move between 11pm and 5am. Hour and Minute
hands continue to operate normally.
Eco Mode switch OFF: the second hand runs
constantly.
Troubleshooting
The wonderful advantage of owning an UltrAtomic clock is that it is
virtually trouble free. If it does not receive an atomic time signal,
consider the following:
Low Batteries – Low batteries are indicated when second
hand stops at the 6, yet the Hour and Minutes hands run as
usual.
The clock must have fresh batteries to receive and process the
time signal.
To reduce the chances of interference with the clock’s
reception, maintain a distance of six feet or more from
electronics such as cordless phones, chargers, dimmers,
wireless gaming systems, televisions, microwave ovens,
routers, computers, baby monitors, etc.
Care and Maintenance
Do not mix old and new batteries
Do not mix Alkaline, Standard, Lithium, or Rechargeable batteries
Always purchase the correct size and grade of battery most suitable
for intended use.
Replace all batteries of a set at the same time.
Clean the battery contacts and also those of the device prior to
battery installation.
Ensure the batteries are installed with correct polarity (+and -).
Remove batteries from equipment which is not to be used for an
extended period of time.
Promptly remove expired batteries.
