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, measuring 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 6.

DETAILED SET-UP GUIDE

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 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 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.

PROGRAM MODE

)

II.

To enter the Program Mode hold down the “MODE/MIN” button for 3 seconds, until the time flashes in the top 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 and E. To exit the setting mode simply wait approximately 10 seconds for the projection alarm to automatically return to normal operation.
