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. Have the indoor station and outdoor remote 3 to 5 apart.

2. Batteries should be out of both units for 10 minutes.

3. Place the batteries into the outdoor remote first then into the indoor station.

(All outdoor remotes must be started before the indoor station)

4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.

In this time the display and sensor will start to talk to each other and the display will

show both the indoor temperature and an outdoor temperature. If the station does not

display both temperatures after the 10 minutes please retry the set up as stated above.

After both indoor and outdoor temperatures are displayed for 10 minutes you can place

your sensor outdoors and set your time.

The remote sensor should be placed in a dry, shaded area. The remote sensor has a range

of 80 feet. Any walls that the signal will have to pass through will reduce distance. An

outdoor wall or window will have 20 to 30 feet of resistance and an interior wall will

have 10 to 20 feet of resistance. Your distance plus resistance should not exceed 80 ft. in

a straight line.

NOTE: Fog and mist will not harm your remote sensor but direct rain must be avoided.

To complete the set up of your temperature station after the 10 minutes have passed

please follow the steps beginning on page 6.

BATTERY INSTALLATION

A. REMOTE TEMPERATURE SENSOR

1. Remove the battery cover. Observing the correct polarity,

install 2 AA batteries. The batteries will fit tightly (to avoid

start-up problems make sure that they do not spring free

during installation).

2. Replace the battery cover.

B. 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.

Note: After the batteries have been installed a tone will sound, and the LCD (Liquid

Crystal Display) will activate. The indoor temperature and the remote temperature will

be displayed (within three minutes). 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 10 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.

2. Projection of time and/or remote temperature

3. EL backlight

4. Six modes of date/seconds/temperature display

5. Indoor temperature

6. Remote outdoor temperature

7. Dual alarms

B. RADIO-CONTROLLED TIME AND DATE

1. The projection alarm will automatically search for the time signal upon initial set-up

and every night.

2. When the signal is being received, there will be a “tower” icon flashing to the left of the

time display.

3. When the time signal has been received successfully, the tower icon will remain

steady until midnight.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

C. PROJECTION OF TIME AND/OR REMOTE TEMPERATURE

1. When plugged into an AC outlet, the projection alarm can continuously project the

time and/or remote temperature.

2. When operating on batteries alone, the projection alarm will only project when a button

is pressed.

3. The projection will auto-focus for display from three to six feet away. A dark

surrounding will be necessary to clearly see the projection.

4. The default is projecting time (Hour and Minutes). The projection alarm can be se to

project the time (M0), remote temperature (M1), or alternating between time and

remote temperature (M2) by pressing the “DISPL” button. The selected display mode

will flash on the lower left as “M0”, “M1” or “M2”.

5. The direction of the display can also be rotated 360°in 90°increments by pressing the

directional button. There is no display on the LCD that signifies the direction.

6. The projector case can be rotated 180°to further help orient the projected display.

7. The intensity of the projection can be adjusted to three different settings as well as

turned “off” by pressing the light Intensity button. When turned off, the projection will

only come on when a button is pressed. The intensity cannot be set for the projected

display when set to “off”. When only batteries are used, the intensity setting is set to

“off” with no other options.

D. EL BACKLIGHT

1. The projection alarm has an EL backlight designed for night-viewing. This will light up

for 2 seconds whenever a button is pressed.

2. The EL backlight cannot be turned on constantly; this would drain the batteries and

burn out the EL.

E. INDOOR TEMPERATURE

1. The projection alarm measures indoor temperature with an internal sensor.

2. This temperature is displayed in °F or °C, depending on the time format (12 or 24 hour

mode). When in 12-hour format, the temperature will be in °F. When in 24-hour mode,

the temperature will be in °C.

3. The indoor temperature will take time to adjust to the surrounding temperature as the

sensor is inside the case.

4. If the remote temperature is placed next to the projection alarm, more often than not

the temperature will not be exact with one another. This is not a defect, but simply

reflects the difference in measuring methods. The remote temperature is designed for

changing temperature at a wide range.

F. REMOTE TEMPERATURE

1. The projection alarm comes with a remote temperature sensor. When set up properly,

the projection alarm will receive and display the remote temperature.

2. It is important to power up the sensor first, then the projection alarm. If batteries are

removed in the remote, the projection alarm MUST be re-set by removing power

sources and re-starting.

3. The remote temperature is measured within the remote temperature and transmitted

to the projection alarm. If outdoor temperature is desired, simply mount the remote

sensor outside. It is recommended to mount the sensor on the North side of the house

away from sources of heat or cold (away from direct sunlight, windows, vents, etc.).

4. The range of the sensor is 80 feet in open space. While the signal is able to penetrate

walls, it will decrease the range. Concrete and metal structures offer the most

resistance.

5. The sensor should not be mounted on a metal surface.

6. The sensor and projection alarm should be kept away from other sources of possible

interference including cordless appliances (telephones, baby monitors), microwave

ovens, and other strong electrical appliances.

7. The remote temperature is displayed in °F or °C, depending on the time format (12 or

24-hour mode). When in 12-hour format, the temperature will be in °F. When in 24-

hour mode, the temperature will be in °C.
