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

+ C -

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.

www.nist.gov/pml/div688/grp40/wwvb.cfm

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.
