ABOUT WWVB (Radio Controlled Time)

The NIST (National Institute of Standards and Technology-Time and Frequency Division) WWVB

radio station is located in Ft. Collins, Colorado, and transmits the exact time signal continuously

throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away

through the internal antenna in the projection alarm. However, due to the nature of the Earth’s

Ionosphere, reception is very limited during daylight hours. The projection alarm will search for a

signal every night when reception is best.

The WWVB radio station receives the time data from the NIST Atomic clock in Boulder, Colorado.

A team of atomic physicists is continually measuring every second, of every day, to an accuracy of

ten billionths of a second per day. These physicists have created an international standard, mea-

suring a second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum. For more detail,

visit http://www.boulder.nist.gov/timefreq.htm. To listen to the NIST time, call (303)499-7111. This

number will connect you to an automated time, announced at the top of the minute in “Coordinated

Universal Time”, which is also known as Greenwich Mean Time (GMT). This time does not follow

Daylight Saving Time changes. After the top of the minute, a tone will sound for every second. It is

possible that your projection alarm may not be exactly on the second due to the variance in the

quartz. However, the clock will adjust the quartz timing over the course of several days to be very

accurate; under 0.10 seconds per day.

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. Place the batteries into 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 both the indoor temperature and humidity. If the station does not

display both indoor temperature and indoor humidity after the 15 minutes please retry the set up

as stated above. After both indoor temperature and indoor humidity are displayed for 15 minutes

you can place your 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 10.

DETAILED SET-UP GUIDE

I. BATTERY INSTALLATION

A. PROJECTION ALARM

1. Remove the battery cover.

2. Observe the correct polarity, and install 2 AA batteries.

3. In addition or instead of inserting batteries, the AC adapter can be used. Simply plug the adapter

into the receptacle on the underneath of the alarm clock and then plug in adapter.

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 a tone will sound, and the LCD (Liquid Crystal Display)

will activate.

• The indoor temperature/humidity will be displayed. Also, the time will appear as “-:—”.

• 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 remain on “-:—”).

• 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 “-:—” will remain in the time LCD.

• The projection alarm will conduct a WWVB search every hour until the rst 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 12:00 am 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

if the wire is too close it can cause weakened reception sensitivity.
