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.
To complete the detailed set-up of your temperature station after
the 15 minutes have passed, please follow the steps beginning on
page 6.
NOTE: Direct rain will damage your remote temperature sensor. Fog
and mist, however, will not harm the sensor.

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).

13
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).
G. TIME ALARM
1. SETTING THE ALARM

14
a. Press and hold “AL/HOUR” button for 3 seconds until the
alarm time is flashing.
b. Press and release “AL/HOUR” to advance the hour, and
“SET/+/MIN” to advance the minute. The time will
display “PM” if set to PM, and display nothing if set to
AM.
c. The projection alarm clock will revert to normal operation
when no buttons are pressed for 15 seconds. The alarm
is now set and activated.
2. ACTIVATING/DEACTIVATING THE ALARM
a. After entering the alarm setting mode, the alarm is
activated.
b. To toggle between activating and deactivating the alarm,
press the “AL/HOUR” button briefly. “(((●)))”will be
displayed above the time display when the alarm is
activated.
3. TURNING ALARM OFF (WHILE SOUNDING)
a. While the alarm is sounding, press and release the
“SNOOZE/ADVANCE MODE” bar to disable the alarm
for 10 minutes.
b. After the “SNOOZE/ADVANCE MODE” bar is pressed
the alarm icon will flash.
c. To disable the alarm for 24 hours, press and release any
button other than the “SNOOZE/ADVANCE MODE” bar
or display direction buttons.
NOTE: The alarm will sound for 120 seconds if the “SNOOZE/ADVANCE
MODE” button is not pressed. The alarm speeds up twice, once
after 20 seconds and again after 50 seconds.

Cloudy Rainy
Sunny
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
1. WEATHER FORECAST ICONS
The weather forecast can be displayed as follow:
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.

16
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: 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.
NOTE: Once the weather tendency indicator has registered a change in air
p
ressure, it will remain
p
ermanentl
y
visualized on the LCD.

17
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

18
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.
