TO INSTALL AND REPLACE BATTERIES IN THE WEATHER
PROJECTION STATION
The Weather Projection Station uses 3 x AA,
IEC LR6, 1.5V batteries. To install and
replace the batteries, please follow the steps
below:
1. Insert finger or other solid object in
the space at the bottom center of the
battery compartment and lift up to
remove the cover.
2. Insert batteries observing the correct
polarity (see marking).
3. Replace compartment cover.
TO INSTALL AND REPLACE BATTERIES IN THE THERMO-
HYGRO SENSOR
The Thermo-hygro sensor uses 2 x AA, IEC LR6, 1.5V batteries. To install and
replace the batteries, please follow the steps below:
1. Remove the battery cover.
2. Insert the batteries, observing the correct
polarity (see marking).
3. Replace the battery cover on the unit.
Note:
In the event of changing batteries in any of the units,
all units need to be reset by following the setting up
procedures. This is due to a random security code
assigned by the sensor at start-up. This code must be
received and stored by the Weather Projection Station
in the first 3 minutes of power being supplied to the
sensor.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to
ensure optimum accuracy of these units.
Please participate in the preservation of the environment.
Return used batteries to an authorized depot.
SETTING UP
The Weather Projection Station can be either batteries-operated or
powered by the provided AC-DC adapter.

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“).
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 theWeather 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
following sensor. The Weather Projection Station will number the sensors
in the order of set-up, i.e. the first sensor will have the
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”).
Your Weather Projection Station is now operational!
Note:

If the batteries are used as the main power source:
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.
To connect the AC-DC adapter:
Important!
Make sure that your household voltage is 120V! Otherwise it can result in
damaging your Weather Projection Station.
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.
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“).
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 following sensor. The Weather Projection Station will number the

sensors in the order of set-up, i.e. the first sensor will have the
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”).
Your Weather Projection Station is now operational!
Note:
If the Weather Projection Station is powered through the AC-DC adapter, the
projection will be constantly ON.
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.
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”.
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 .
TO PROJECT THE TIME OR TEMPERATURE ONTO A FLAT
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.
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.
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.
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 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.
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 [phone]. 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.

WEATHER FORECAST AND WEATHER TENDENCY:
WEATHER FORECASTING ICONS:
Weather icons in the third section of LCD that can be displayed in any of the
following combinations:
Sunny Cloudy with sunny intervals Rainy
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.
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.
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).
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
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.
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.

INDOOR RELATIVE HUMIDITY AND INDOOR TEMPERATURE:
The indoor temperature and humidity data, the indoor comfort indicator are
automatically updated and displayed on the fourth section of the LCD.
The comfort level indicator:
Comfortable: A happy face icon “☺” indicating a temperature level between
68.0°F and 78.6°F and relative humidity reading between
45% and 65%.
Uncomfortable: A sad face icon “” indicating any value outside the
comfortable range.
TOGGLING AND RESETTING THE INDOOR READINGS:
1. Press the HOUR/IN key to toggle between the indoor current, MIN/MAX
temperature and humidity data. The time and dates of the recorded
data will also be displayed in the time and calendar sections (for
temperature data only).
2. To reset the MIN/MAX data, press and hold the HOUR/IN key for about
4 seconds. This will reset all recorded indoor data to the current
temperature and humidity readings.
