TO INSTALL AND REPLACE BATTERIES IN THE WEATHER
PROJECTION STATION

TO INSTALL AND REPLACE BATTERIES IN THE THERMO­HYGRO 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.

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.

2. Insert the batteries, observing the correct
polarity (see marking).

BATTERY CHANGE:

It is recommended to replace the batteries in all units on an annual basis to
ensure optimum accuracy of these units.

SETTING UP

The Weather Projection Station can be either batteries-operated or
powered by the provided AC-DC adapter.

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.

Please participate in the preservation of the environment.
Return used batteries to an authorized depot.

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 tempe rature
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 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.

this in mind when positioning the sensor. Also the batteries may be reduced in
power.

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.

2. Avoid placing the Thermo-hygro sensor onto or in the immediate

proximity of metal window frames.

3. 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.

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.

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).

POSITIONING THE THERMO-HYGRO SENSOR:

Each sensor is supplied with 2 wall mounting screws and plastic anchors. To
wall mount simply:

Note:
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:

• 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.

1. Secure the wall base onto
a desired wall using the
screws and plastic anchors.

2. Insert the sensor to the wall
base.

• Do not submerge the units in water.

• Immediately remove all low powered batteries to avoid leakage and

damage. Replace only with new batteries of the recommended type.

• 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.
