GLOSSARY OF COMMON TERMS

LCD

“LCD” is an acronym for ”Liquid Crystal Display”. This is a common type of display screen used in televisions, computers, watches, and digital clocks.

LED

“LED” is an acronym for “Light-Emitting Diode”. This type of light is used to illuminate a variety of displays such as a digital clock or watch.

NIST

The National Institute of Standards and Technology (Time and Frequency division) maintains the primary frequency standard for the United States. The NIST also coordinates the United States time and frequency standards with other world standards. The NIST provides time and frequency services for United States clientele.

WWVB

The WWVB is an AM radio station in Ft. Collins, Colorado, managed by the NIST. The WWVB’s function is to broadcast time-of-day information derived from the NIST atomic clock, located in Boulder, Colorado.

ATOMIC CLOCK

An atomic clock is an extremely accurate time device measuring time by the movements of electrons in cesium atoms. The NIST atomic clock is one of the most precise clocks in the world, accurate to 10 billionths of one second. The NIST’s atomic clock contributes to the international group of clocks calculating the Coordinated Universal Time (UTC)—the official world time.

RADIO CONTROLLED TIME

A radio controlled time device is often confused with an atomic clock. However, a radio controlled time device receives its time information from the atomic clock each day through an internal antenna. The radio controlled time device searches for an exact time signal every night when the signal from the WWVB is the strongest. The signal can be received up to 2,000 miles away through a radio controlled time device.

For more information regarding the NIST, WWVB, atomic clock, and radio controlled time, please visit the NIST official website: http://www.boulder.nist.gov/timefreq/stations/wwvb.htm

I. QUICK SET-UP GUIDE

Hint: Use good quality alkaline batteries and avoid rechargeable batteries.

1.We recommend beginning the set-up procedure at night when the WWVB signal is easiest to receive.

2.It is also highly recommended to set the projection alarm in a window or other area free of interference in the area of your home that is closest to Colorado (the source of the WWVB signal).

NOTE: The above steps are not required but can help the projection alarm receive the signal faster.

3.Install the batteries in the projection alarm clock.

4.DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.

NOTE: It is important to not press any buttons after inserting batteries as this will interrupt the WWVB search sequence.

In this time the display will show the indoor temperature. If the station does not display the indoor temperature after the 15 minutes please retry the set-up as stated above. After the indoor temperature displays for 15 minutes you may place the projection alarm in your desired location.

To complete the set-up of your temperature station after the 15 minutes have passed, please follow the steps beginning on page 6.

A.

BATTERY INSTALLATION

1.

Remove the battery cover on the backside of

the projection alarm.

2.

Observe the correct polarity, and install 2 AA

batteries.

3.

In addition to or instead of installing batteries,

the AC adapter can be used. Simply plug the

adapter into the receptacle on the underneath

AC adapter

side of the alarm clock, and then plug in the

adapter.

receptacle

4.Replace the battery cover.

5.The projector will activate and remain on if the alarm clock is plugged in. If only batteries are used, the projector will only be activated when a button is pressed. The projection is a red light, not harmful under normal usage, although care should be taken to not look directly into the light.

Notes:

After the batteries have been installed, the LCD will activate, and you will hear a beep.

The indoor temperature will be displayed, and the time will appear as “12:00 AM”.

The WWVB search is automatically initiated, and a tower icon appears and flashes with the time colon (no tower icon will appear if the WWVB is too weak to be detected, and the time display will start from 12:00 AM).

While the WWVB search is being conducted various numbers will appear in the time display.

After 15 minutes, the projection alarm will either display the WWVB time, or discontinue the search if the time is not found. If the search is cancelled the time will continue from 12:00 AM.

The projection alarm will conduct a WWVB search every hour until the first signal is found.

Once the WWVB time is found, a search is automatically conducted nightly at midnight.

If the signal is found at midnight, the tower icon will remain, if not, another search will take place every hour (until 6:00 AM) until the signal is found successfully.

If no signal is found during this period, the tower icon will not appear, and the clock will search again at midnight the next night.

The radio-controlled time receiver is located on the bottom side of the projection alarm. When using the AC adaptor be sure to keep the adapter cord away from the bottom side of the unit; as it can cause weakened reception of the radio controlled signal.

III. PROGRAM MODE

To enter the Program Mode, hold down the “MODE/MIN” button for 3 seconds, until the time zone flashes at the bottom of the display. The Program Mode Guide is laid out in a manner that allows you to program each function separately, or you can follow the instructions entirely to program the projection alarm. Complete programming is usually done for the initial set-up, and will require you to skip step 1 and 2 of programming sections D-H. To exit the setting mode simply wait approximately 10 seconds for the projection alarm to automatically return to normal operation.

Radio Controlled Analog Clock
Quick Setup Instructions
Welcome to the world of atomic timekeeping technology. W e hope you
will enjoy the convenience of never having to set your clock again and
the confidence of knowing exactly what time it is.
A locking pin may be placed into the movement at the factory to
prevent shifting of the hands during shipment. Remove the locking
pin directly below the Reset button. This will unlock the hands and
enable the clock to set itself after receiving the signal.
Set the clock to your time zone by moving the indicator arrow to
appropriate zone: P (UTC-8 Pacific Time), M (UTC-7 Mountain
Time), C (UTC-6 Central Time), E (UTC-5 Eastern Time)
Enable the Daylight Savings Time Auto Adjust feature by moving
the DST switch to “ON”. If you are in a time zone that does not
follow DST, make sure you set the DST mode to “OFF”. The
Daylight Savings Time feature is disabled when the switch is set to

procedures takes approximately 3 to 10 minutes after all hands
have set to the 12:00 position. If a signal is found within the first 3
to 10 minutes, the clock will set to the correct time. If the clock
does not receive a radio signal soon after activated, the clock will
start running from the 12:00 position and will continue to run. In
this case, do not attempt to reset the hands manually even though
the time displayed on the clock is incorrect. The clock is
synchronizing to the WWVB signal and once the radio signal is
decoded, the hands will automatically adjust to the correct time.
The WAVE button can be used to attempt an enforced signal
receipt. To activate, hold the WAVE button down for 3+ seconds.
Once the WAVE feature is activated, the hands will automatically
reset to the 12:00 position, and the movement will attempt to
enforce a signal receipt from Fort Collins, CO. If the movement
successfully receives the signal, the clock will reset automatically to
the correct time. Generally, the signal enforced receipt takes
approximately 3-8 minutes. If the clock still fails to receive the
signal while in the WAVE mode, the clock will automatically leave
the WAVE mode. In this case, set the clock manually according to
instructions below and the time keeping function will be controlled
Manual Set: On rare occasions in certain areas, the clock may not
be able to utilize the radio-controlled function because of either 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.
If it is necessary to set the clock manually, press and hold the SET
button for 3+ seconds to activate the manual mode. Once the
clock is in manual mode, there are two ways to move the minute
hand forward. Hold the SET button down to move the minute hand
forward consistently. Or, press the SET button rapidly (more than
once per second) to move the minute hand forward step by step (in
minute increments). Use these features to move the minute hand
forward until the correct time is set. The clock will automatically
leave manual mode after the SET button is not pressed for 6+
Reset: If the clock does not respond to the various function
modes, you can reset the clock by pressing the RESET button on
Internal Synchronization: Once the clock has been set correctly
by the radio signal, the clock’s CPU operates continuously. To
ensure accuracy, the clock synchronizes the position of the second
and minute hands to the time calculated by the CPU every day.
Second hand synchronization occurs at 1:30 a.m. and 9:30 a.m.
and minute hand synchronization occurs between 1:50 and 2:01
Signal Interference: In some cases, the signal can be affected by
weather conditions and electrical interferences, or the location of
the clock itself may result in poor reception. If the clock has not
synchronized to the correct time within a few days of activation, you
may wish to move the clock to a different location. Try to place it
near an outside wall closest to the direction of Colorado. Avoid
placing the clock near electrical items such as TVs, microwave
Since the beginning of time, man has been fascinated with the
measurement of time and has devised more accurate machines to trap
and measure time. Today, time is precisely measured in the United
States by the most accurate clock in North America, the Atomic Clock of
the US National Institute of Standards and Technology, Time and
Frequency Division in Boulder, Colorado. A team of atomic physicists
continually measures every second of every day to an accuracy of ten
billionths of a second per day. These physicists have created an
international standard, measuring a second as 9,192,631,770 vibrations
of a Cesium 133 atom in a vacuum. This atomic clock regulates the
WWVB radio transmitter located in Fort Collins, Colorado, where the
exact time signal is continuously broadcast throughout the United States
at 60 kHz to take advantage of stable long wave radio paths found in that
frequency range. Radio waves at these low frequencies use the earth
and the ionosphere as a wave-guide and follow the curvature of the earth
The built in antenna system will receive the WWVB signal anywhere in
North America within 2000 miles of Fort Collins where long-wave radio
reception is undisturbed. A microprocessor activates the receiver and
processes the time signal from Fort Collins overnight.
Through the radio signals, La Crosse Technology atomic clocks always
keep precise time. The changeover from standard time to daylight
saving time, and vice versa, takes place automatically with the same
The La Crosse Technology atomic clock is designed for indoor use. For
indoor locations, select a location to place your radio controlled clock
where it will be at least six feet away from a TV, computer, air conditioner
or other household electrical appliances. The optimal location is near a
window. Windows facing Colorado provide the best signal.
Notes:
Extreme temperatures, vibration, and shock should be avoided to
The WWVB time signal will easily penetrate masonry and wood framed
buildings. The WWVB signal will penetrate almost every residential
building and most steel buildings if they have adequate windows. It is
not possible, however, for the WWVB signal to penetrate most indoor
shopping malls and rooms in the center of large office buildings that do
not have windows. In buildings that WWVB cannot penetrate you may
set the time using the manual time set button. When the clock receives
the WWVB signal it will automatically set the hands to the exact time.
La Crosse Technology atomic clocks do not receive or process
radio controlled ti me signals from Germany’s DCF 77, Japan’s J Ga
AS, or England’s MSFs atomically regulated transmitters. La
Crosse Technology atomic clocks can be manually set and used
anywhere. Please Note: WWVB time will over ride a manual setting.
For more information on the NIST and radio controlled time, see
The National Institute of Standards and Technology and WWVB encode
a special DST “bit” in the WWVB transmission for DST. Your La Crosse
Technology clock will read this information and automatically advance
the hands one hour in the spring and eleven hours in the fall.
