GLOSSARY OF COMMON TERMS  
NIST*  
The National Institute of Standards and Technology 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.  
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.  
CELSIUS (°C)  
Celsius is metric system’s unit of measurement used to calculate temperature.  
FAHRENHEIT (°F)  
Fahrenheit is the common unit of measurement used to calculate temperature the  
United States.

QUICK SET-UP GUIDE  
Hint: Use good quality alkaline batteries and avoid  
rechargeable batteries.  
1. Place the projection alarm and remote temperature  
sensor 3-5 feet apart.  
2. Batteries should not be installed into either unit for 15  
minutes.  
3. Place the batteries into the remote temperature sensor  
first and then into the projection alarm.  
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.  
In this time the display and the sensor will begin to communicate  
with each other. The display will show both the indoor  
temperature/humidity and an outdoor temperature. If the station  
does not display both temperatures and the indoor humidity after  
the 15 minutes, please retry the set-up in the instructions above.  
After both indoor and outdoor temperatures are displayed for 15  
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 has  
to pass through will reduce distance of the range. An outdoor wall  
or window has up to 20 feet of resistance and an interior wall has  
up to 10 feet of resistance. Your distance plus resistance should  
not exceed 80 feet in a straight line.  
NOTE: Direct rain will damage your remote temperature sensor. Fog  
and mist, however, will not harm the sensor.  
To complete the detailed set-up of your temperature station after  
the 15 minutes have passed, please follow the steps beginning on  
page 6.

NOTES:  
After the batteries have been installed a tone will sound, and the  
LCD (Liquid Crystal Display) will activate.  
The indoor temperature/humidity and the remote temperature 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.  
B. PROGRAM MODE  
To enter the Program Mode hold down the “SET/+/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 F and G. To exit the setting mode simply wait approximately 10  
seconds for the projection alarm to automatically return to normal  
operation.

FEATURES & OPERATIONS  
A. FEATURES  
1. Projection of time and/or remote temperature  
2. EL backlight  
3. Display of indoor temperature/humidity or alarm time  
4. Indoor temperature and humidity  
5. Remote outdoor temperature  
6. Time alarm  
7. Weather Forecast & Weather boy icon  
B. PROJECTION OF TIME AND/OR REMOTE  
TEMPERATURE  
1. When plugged into an AC outlet, the projection alarm can  
continuously project the time and remote temperature.  
2. When operating on batteries alone, the projection alarm will only  
project when the SNOOZE/ADVANCE MODE button is pressed  
or the alarm is sounding.  
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 projection alarm will toggle between the time and outdoor  
temperature when projecting; either when the  
“SNOOZE/ADVANCE MODE” bar is pressed or continuously  
when using the AC adaptor.  
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.  
C. EL BACKLIGHT  
1. The projection alarm has an EL backlight designed for night-  
viewing. This will light up for 4 seconds whenever the  
SNOOZE/ADVANCE MODE button is pressed.  
2. The EL backlight cannot be turned on constantly; this would  
drain the batteries.  
D. INDOOR TEMPERATURE  
1. The projection alarm measures indoor temperature with an  
internal sensor.  
2. This temperature is displayed in °F/°C (°F is the default).  
12  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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 temperatures 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 wider range.  
E. INDOOR HUMIDITY  
1. The projection alarm measures indoor humidity with an internal  
sensor.  
2. This humidity is displayed as a percentage (%).  
3. The indoor humidity will take time to adjust to the surrounding  
humidity as the sensor is inside the case.  
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 remote temperature sensor first,  
then the projection alarm clock. If batteries are removed in the  
remote temperature sensor, the projection alarm clock MUST be  
re-set by removing power sources and re-starting.  
3. The remote temperature is measured within the remote  
temperature sensor and transmitted to the projection alarm  
clock. If outdoor temperature readings are desired, simply mount  
the remote temperature 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, the walls 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 (the default is  
°F).

H. CHANGING DISPLAY MODE (INDOOR  
TEMPERATURE/HUMIDITY OR ALARM TIME)  
There are two possible display modes in the indoor temperature/humidity  
section of the LCD (lower left). To change the display press and release  
the “SET/+/MIN” button to toggle between the two modes.  
I. WEATHER FORECAST  
& WEATHER TENDENCY INDICATOR  
Weather forecast icon  
Weather tendency indicator  
Weather Boy icon  
1. WEATHER FORECAST ICONS  
The weather forecast can be displayed as follow:  
Rainy  
Sunny  
Cloudy  
For every sudden or significant change in the air pressure, the  
weather icons will update accordingly to represent the change in  
weather. If the icons do not change, then it means either the air  
pressure has not changed or the change has been too slow for  
the weather projection station to register. However, if the icon  
displayed is a sun or raining cloud, there will be no change of  
icon if the weather gets any better (with sunny icon) or worse  
(with rainy icon) since the icons are already at their extremes.  
The icons displayed forecasts the weather in terms of getting  
better or worse and not necessarily sunny or rainy as each icon  
indicates. For example, if the current weather is cloudy and the  
rainy icon is displayed, it does not mean that the product is faulty  
because it is not raining. It simply means that the air pressure  
has dropped and the weather is expected to get worse--but not  
necessarily rainy.  
15  
Download from Www.Somanuals.com. All Manuals Search And Download.  
NOTE: After setting up, readings for weather forecasts should be  
disregarded for the next 12-24 hours. This will allow sufficient time  
for the projection alarm clock to collect air pressure data at a  
constant altitude and therefore result in a more accurate forecast.  
Common to weather forecasting, absolute accuracy cannot be  
guaranteed. The weather forecasting feature is estimated to  
have an accuracy level of about 75% due to the varying areas  
the projection alarm clock station has been designed for use. In  
areas that experience sudden changes in weather (for example  
from sunny to rain), the projection alarm clock will be more  
accurate compared to use in areas where the weather is  
stagnant most of the time (for example mostly sunny).  
If the projection alarm clock is moved to another location  
significantly higher or lower than its initial standing point (for  
example from the ground floor to the upper floors of a house),  
discard the weather forecast for the next 12-24 hours. By doing  
this, the projection alarm clock will not mistake the new location  
as being a possible change in air-pressure when really it is due  
to the slight change of altitude.  
2. WEATHER TENDENCY INDICATOR  
Working together with the weather icons is the weather tendency  
indicators (located to the right of the weather icons). When the  
indicator points upwards, it means that the air-pressure is  
increasing and the weather is expected to improve, but when  
indicator points downwards, the air-pressure is dropping and the  
weather is expected to become worse.  
Taking this into account, one can see how the weather has  
changed and is expected to change. For example, if the indicator  
is pointing downwards together with cloud and sun icons, then  
the last noticeable change in the weather was when it was sunny  
(the sun icon only). Therefore, the next change in the weather  
will be cloud with rain icons since the indicator is pointing  
downwards.  
NOTE: Once the weather tendency indicator has registered a change in air  
pressure, it will remain permanently visualized on the LCD.

3. WEATHER BOY FORECASTING ICONS:  
A total of 15 Weather Boy icons combinations can be displayed  
depending on outdoor temperature and air pressure recorded  
from the remote temperature sensor only.  
Once the temperature and air pressure are recorded, the  
projection alarm clock automatically display the appropriate  
Weather Boy icon as an indication of current weather and  
suggestion for dressing up accordingly. The icon will remain  
permanently visualized on the LCD once it registered a change  
in temperature and air pressure.  
MOUNTING  
MOUNTING THE REMOTE TEMPERATURE SENSOR  
The remote temperature sensor can be mounted 2 different ways:  
A. Mounting with screws  
17  
Download from Www.Somanuals.com. All Manuals Search And Download.  
B. Mounting with adhesive tape  
A. MOUNTING WITH SCREWS  
1. Remove the mounting bracket from the remote temperature sensor.  
The bracket should snap off easily.  
2. Place the mounting bracket over the desired location. Through the  
three screw holes of the bracket, mark the mounting surface with a  
pencil.  
3. Where marked, start the screw holes into the mounting surface.  
4. Screw mounting bracket onto the mounting surface. Ensure that the  
screws are flush with the bracket, but take care to not over-tighten.  
5. Snap the remote temperature sensor onto the mounted bracket.  
B. MOUNTING WITH ADHESIVE TAPE  
1. With a nonabrasive solution, clean and dry the back of the mounting  
bracket and the mounting surface to ensure a secure hold. The  
mounting surface should be smooth and flat.  
2. Remove the protective strip from one side of the tape. Adhere the  
tape to the designated area on the back of the mounting bracket.  
Remove the protective strip from the other side of the tape. Position  
the remote temperature sensor in the desired location, ensuring that  
the projection alarm clock can receive the signal.  
MAINTENANCE & CARE  
Extreme temperatures, vibrations, and shock should be  
avoided to prevent damage to the units.  
Clean displays and units with a soft, damp cloth. Do not use  
solvents or scouring agents—they may mark and damage  
the displays and casings.  
Do not submerge in water.  
Immediately remove all low powered batteries to avoid  
leakage and damage.  
Replace with new batteries only, and of recommended size.  
Opening the casings invalidates the warranty.
