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 on page 7.

DETAILED SET-UP GUIDE

Important: Insert batteries into the sensor first, then into the alarm clock. Do not

press any buttons until remote temperature is displayed.

II. 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 3 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.

6. Either wait for the WWVB reception or manually set the time and date,

making sure to set the correct time zone.

III. PROGRAM MODE

To enter the Program Mode hold down the “SET” button for 1 second, until the time

zone (“-5” default) flashes in the lower left. Press the “SNOOZE” button at any

time to exit the Program Mode, or wait approximately 15 seconds for the projection

alarm to automatically return to normal operation.

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

Light intensity Display Mode Display Direction
