BATTERY INSTALLATION:  
1. First, insert the batteries into the Weather Projection Station (see “To  
install and replace batteries in the Weather Projection Station”).  
Once the batteries are in place, all segments of the LCD will light up  
briefly and a short signal tone will sound. Then the ALM1 6:00, the indoor  
temperature and humidity, the time as 12:00, the date as WE 1.1., the  
moon icon, the weather icons (sun and clouds) will be displayed. If the  
indoor temperature and indoor humidity are not displayed after 15  
seconds, remove the batteries and wait for at least 3 minutes before  
reinserting them. Once the indoor data is displayed proceed to step 2.  
2. Within 4 minutes of activating the Weather Projection Station, place the  
batteries into the sensor (see “To install and replace batteries in the  
Thermo-hygro Sensor“).  
temperature/humidity displayed with the number 1 against it and so on.  
5. With less than 3 sensors received, the Weather Projection Station will try  
to pick up the remaining one in approximately another 3 minutes. If 3  
sensors are received, the Weather Projection Station will stop further  
reception.  
6. Once the outdoor temperature and the humidity have been received and  
displayed on the Weather Projection Station, the WWVB time code  
reception is automatically started. This takes typically between 6-8  
minutes in good conditions.  
7. If after 10 minutes, the WWVB time has not been received, use the SET  
key to manually enter a time initially. The clock will automatically attempt  
to receive the WWVB time from 12:00 to 6:00 a.m. for a successful  
reception. When WWVB reception signal is successful, the received time  
will override the manually set time. The date is also updated with the  
received time. The next reception attempt will occur on the following day.  
(Please refer to notes on “About WWVB Radio controlled Time” and  
“Manual Time Setting”).  
3. After inserting the batteries into the sensor, the Weather Projection  
Station will start receiving data from the sensor. The outdoor temperature  
and humidity should then be displayed on the Weather Projection Station.  
If this does not happen after 3 minutes, the batteries will need to be  
removed from both units and reset from step 1.  
4. The Weather Projection Station can receive up to 3 remote Outdoor  
Thermo-hygro sensors. If you have purchased additional sensors, repeat  
from step 3 for all extra sensors. However, ensure that you leave 10  
seconds in between the reception of the last sensor and the set-up of the  
Your Weather Projection Station is now operational!  
Note:  
 
If the batteries are used as the main power source:  
1.  
Connect the AC-DC adapter to a wall socket. Plug the adapter into the  
jack at the side of the Weather Projection Station. All segments of the  
LCD will light up briefly and a short signal tone will sound. Then the  
ALM 1 6:00, the indoor temperature and humidity, the time as 12:00,  
the date as WE 1.1., the moon icon, the weather icons (sun and clouds)  
will be displayed. If the indoor temperature and indoor humidity are not  
displayed after 15 seconds, remove the batteries and wait for at least 3  
minutes before reinserting them.  
1.  
Projected image brightness, alarm volume and back-light strength will  
be weaker when batteries are low  
2.  
Battery life time will be much less than 1 year; depending on the  
frequency of projection and alarm.  
TO USE THE PROJECTOR POWER ADAPTER  
The unit comes with an AC-DC adapter for using the projector for an extended  
period of time, such as throughout the night.  
2.  
3.  
Within 4 minutes of activating the Weather Projection Station, place the  
batteries into the sensor (see “To install and replace batteries in the  
Thermo-hygro Sensor“).  
To connect the AC-DC adapter:  
After inserting the batteries into the sensor, the Weather Projection  
Station will start receiving data from the sensor. The outdoor  
temperature and humidity should then be displayed on the Weather  
Projection Station. If this does not happen after 3 minutes, the batteries  
will need to be removed from both units and reset from step 1.  
The Weather Projection Station can receive up to 3 remote Outdoor  
Thermo-hygro sensors. If you have purchased additional sensors,  
repeat from step 3 for all extra sensors. However, ensure that you leave  
10 seconds in between the reception of the last sensor and the set-up  
of the following sensor. The Weather Projection Station will number the

temperature/humidity displayed with the number 1 against it and so on.  
With less than 3 sensors received, the Weather Projection Station will  
try to pick up the remaining one in approximately another 3 minutes. If  
3 sensors are received, the Weather Projection Station will stop further  
reception.  
Once the outdoor temperature and the humidity have been received  
and displayed on the Weather Projection Station, the WWVB time code

key to manually enter a time initially. The clock will automatically  
attempt to receive the WWVB time from 12:00 to 6:00 a.m. for a  
successful reception. When WWVB reception signal is successful, the  
received time will override the manually set time. The date is also  
updated with the received time. The next reception attempt will occur on  
the following day. (Please refer to notes on “About WWVB Radio  
controlled Time” and “Manual Time Setting”).  
Note:  
If the Weather Projection Station is powered through the AC-DC adapter, the  
projection will be constantly ON.

7.  
If the Weather Projection Station is battery operated, only when the SNOOZE  
key is pressed, the projection will turn ON. Once the SNOOZE key is released,  
there will be no projection.  
USING BOTH BATTERIES THE POWER ADAPTOR  
If the Weather Projection Station is first powered by batteries and the AC-DC  
adapter is subsequently used for extended period of time, the main power  
source of the Weather Projection Station will switch to AC power. The  
batteries will then act as a backup power source in the case of power failure.  
RESETTING  
The Weather Projection Station and the Thermo-hygro sensor need to be  
reset when one of the following conditions occur:  
Unsuccessful 433MHz signal reception.  
Malfunction on the units.  
Batteries replacement.  
Your Weather Projection Station is now operational!  
For resetting, remove all batteries from the units and unplug the AC-DC  
adapter from any power source. Wait at least for 3 minutes before powering  
 
up the Weather Projection Station again. Proceed from step 1 in “Setting  
Up”,“Battery Installation” or “How to use the Projector Adaptor”.  
3.  
Adjust the projection image in an upright position with the  
key.  
Note:  
If more than one Thermo-hygro Sensor is used, only the temperature from  
sensor 1 will be projected.  
Note:  
The projection brightness is not adjustable as it is constantly set at its brightest  
level.  
HOW TO USE THE PROJECTOR  
The projector projects the current time and the current outdoor temperature  
onto the ceiling, preferable within a darkened room. The projection image  
can also be adjusted in 4 upright positions, each with a rotation of 90º by  
using the  
key .  
ABOUT WWVB RADIO CONTROLLED TIME  
TO PROJECT THE TIME OR TEMPERATURE ONTO A FLAT  
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 Weather Projection Station. However, due to the nature  
of the Earth’s Ionosphere, reception is very limited during daylight hours. The  
Weather Projection Station will search for a signal every night when reception  
is best.  
SURFACE:  
The projector will only project the current time, outdoor temperature or  
alternate between time/outdoor temperature only.  
1.  
Point the projection lens to the appropriate direction (maximum distance  
of the projection is 6 feet/2 meters).  
2.  
Press the DISPL key to select the desired mode for the projection.  
There are 3 display modes:  
M0 – projecting the current time only.  
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  
M1 – projecting the current outdoor temperature only.  
M2 – projecting by switching the display of the current time and the  
current outdoor temperature for every 5 seconds.  
 
as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum. For more  
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 Weather Projection Station 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.

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.  
Large Waxing Gibbous  
Crescent  
Moon Tide:  
The moon Tide information is indicated on the left side of the moon phase icon  
as follow:  
 
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.  
hours. By doing this, the Weather Projection Station 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.  
WEATHER TENDENCY INDICATOR  
Working together with the weather icons is the weather tendency indicators  
(located on the left and right sides 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.  
Note:  
After setting up, readings for weather forecasts should be disregarded for the  
next 12-24 hours. This will allow sufficient time for the Weather Projection  
Station to collect air pressure data at a constant altitude and therefore result in  
a more accurate forecast.  
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.  
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 Weather Projection Station has been  
designed for use. In areas that experience sudden changes in weather (for  
example from sunny to rain), the Weather Projection Station will be more  
accurate compared to use in areas where the weather is stagnant most of the  
time (for example mostly sunny).  
Note:  
Once the weather tendency indicator has registered a change in air pressure,  
it will remain permanently visualized on the LCD.  
If the Weather Projection Station 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  
 
data will also be displayed in the time and calendar sections (for

ABOUT THE OUTDOOR THERMO-HYGRO SENSOR  
The range of the Thermo-hygro Sensor may be affected by the temperature.  
At cold temperatures the transmitting distance may be decreased. Please bear  
this in mind when positioning the sensor. Also the batteries may be reduced in  
power.  
Twice to show sensor 3  
Three times to return to sensor 1  
Note: The sensor number will only be displayed if there is more than one  
sensor being used.

To reset the MIN/MAX outdoor temperature, and the time at which they  
were recorded, press and hold the MIN/OUT key for about 4 seconds.  
This will reset all MIN/MAX data recorded to the displayed values for  
that particular sensor.  
CHECKING FOR 433MHz RECEPTION  
If the outdoor temperature and humidity data is not being received within  
three minutes after setting up (the display shows “- -. - °F” and “- -%” on the  
outdoor section of the Weather Projection Station after 3 attempts during  
normal operation), please check the following points:  
 
1.  
The distance of the Weather Projection Station or sensor should be at  
least 6 feet (2 meters) away from any interfering sources such as  
computer monitors or TV sets.  
Avoid placing the Thermo-hygro sensor onto or in the immediate  
proximity of metal window frames.  
Using other electrical products such as headphones or speakers  
operating on the 433MHz-signal frequency may prevent correct signal  
transmission or reception. Neighbors using electrical devices operating  
on the 433MHz-signal frequency can also cause interference.  
POSITIONING THE THERMO-HYGRO SENSOR:  
Each sensor is supplied with 2 wall mounting screws and plastic anchors. To  
wall mount simply:  
2.  
3.  
1. Secure the wall base onto  
a desired wall using the  
screws and plastic anchors.  
2. Insert the sensor to the wall  
base.  
Note:  
Note:  
When the 433 MHz signal is received correctly, do not re-open the battery  
cover of either the sensor or Weather Projection Station, as the batteries may  
spring free from the contacts and force a false reset. Should this happen  
accidentally then reset all units (see “Setting up” above) otherwise  
transmission problems may occur.  
Before permanently fixing the sensor wall base, pace all units in the desired  
locations to check that the outdoor temperature and humidity readings are  
receivable. In event that the signal is not received, relocate the sensors or  
move them slightly as this may help the signal reception.  
CARE AND MAINTENANCE:  
The transmission range is around 65-82 feet (20-25 meters) from the sensor to  
the Weather Projection Station (in open space). However, this depends on the  
surrounding environment and interference levels. If no reception is possible  
despite the observation of these factors, all system units have to be reset (see  
“Setting up” above).  
Extreme temperatures, vibration and shock should be avoided as these  
may cause damage to the units and give inaccurate forecasts and  
readings.  
When cleaning the display and casings, use a soft damp cloth only. Do  
not use solvents or scouring agents as they may mark the LCD and  
casings.

Immediately remove all low powered batteries to avoid leakage and

Do make any repair attempts to the units. Return it to their original point  
of purchase for repair by a qualified engineer. Opening and tampering  
with the units may invalidate their guarantee.  
Do not expose the units to extreme and sudden temperature changes,  
this may lead to rapid changes in forecasts and readings and thereby  
reduce their accuracy.
