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
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. and the weather icons 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 remote
temperature/humidity sensor (see “To install and replace batteries in the remote
temperature/humidity sensor“).
3. After inserting the batteries into the remote temperature/humidity sensor, the weather projection station
will start receiving data from the remote temperature/humidity 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 temperature/humidity sensors. If you have
purchased additional remote temperature/humidity sensors, repeat from step 3 for all extra remote
temperature/humidity sensors. However, ensure that you leave 10 seconds in between the reception of
the last remote temperature/ humidity sensor and the set-up of the following remote temperature/
humidity sensor. The weather projection station will number the remote temperature/humidity sensors
in the order of set-up, i.e. the first remote temperature/humidity sensor will have the
temperature/humidity displayed with the number 1 against it and so on.
5. With less than 3 remote temperature/humidity sensor received, the weather projection station will try to
pick up the remaining one in approximately another 3 minutes. If 3 remote temperature/humidity
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 WEATHER PROJECTION STATION POWER ADAPTER
The unit comes with an AC adapter for using the projector for an extended period of time, such as
throughout the night.
To connect the AC adapter:
Important!
Make sure that your household voltage is 120V! Otherwise it can result in damaging your weather
projection station.
1. Connect the AC adapter to a wall socket. Plug the adapter into the jack on the back 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 1.1and the
weather icons 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 remote
temperature/humidity sensor (see “To install and replace batteries in the remote
temperature/humidity sensor“).
3. After inserting the batteries into the remote temperature/humidity sensor, the weather projection
station will start receiving data from the remote temperature/humidity 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 temperature/humidity sensors. If you have
purchased additional remote temperature/humidity sensors, repeat from step 3 for all extra remote
temperature/humidity sensors. However, ensure that you leave 10 seconds in between the reception
of the last remote temperature/humidity sensor and the set-up of the following remote
temperature/humidity sensor. The weather projection station will number the remote
temperature/humidity sensors in the order of set-up, i.e. the first remote temperature/humidity sensor
will have the temperature/humidity displayed with the number 1 against it and so on.
5. With less than 3 remote temperature/humidity sensors received, the weather projection station will try
to pick up the remaining one in approximately another 3 minutes. If 3 remote temperature/humidity
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 adapter, the projection will be constantly ON.
If the weather projection station is battery operated the projection will turn ON only when the SNOOZE key is
pressed. Once the SNOOZE key is released, the projection and E.L. backlight will stay on for approximately
10 seconds.
USING BOTH BATTERIES AND THE POWER ADAPTOR
When using both the AC adaptor and batteries 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 remote temperature/humidity sensor need to be reset when one of
the following conditions occur:
•Unsuccessful 433MHz signal reception.
•Malfunction of the units.
•Batteries need replacement.
For resetting, remove all batteries from the units and unplug the AC adapter from the 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 Projection Station Power Adaptor”.
HOW TO USE THE PROJECTOR
The projector projects the current time and the current outdoor temperature onto the ceiling, only 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 (ideal distance of the projection is 6 feet/2
meters).
2. Press the DISPLAY 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 remote temperature/humidity sensor is used, only the temperature from remote
temperature/humidity sensor 1 will be projected.
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.

6
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.
