HOW TO INSTALL AND REPLACE BATTERIES IN THE PROJECTION CLOCK

The Projection clock uses 3 x AA, IEC LR6, 1.5V batteries. When batteries will need to be replaced, the
low battery icon will appear on the LCD. To install and replace the batteries, please follow the steps
below:

1. Remove the compartment cover at the back of the
projection clock.

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

3. Replace compartment cover.

41

In addition or instead of inserting batteries, the AC adapter can be used:

1. Connect the power adapter to a wall socket

2. Insert the adapter into the jack at the bottom of the clock

3. The Projection clock will now start receiving the DCF time signal. After approximate 3 to 5

minutes, the DCF time will be displayed (Also see "SETTING UP" below) .

Important!

Use only the adapter provided with the projection clock and make sure that your household voltage is
appropriate to the working voltage of the adapter. Otherwise your Projection clock may be damaged.

POWERED WITH THE USE OF AC/DC ADAPTER

If the Projection clock is first powered by batteries and the power adapter is subsequently used for
extended period of time, the main power source of the Projection clock will switch to AC/DC power. The
batteries will then act as a backup power source in case of power failure.

42

HOW TO INSTALL AND REPLACE BATTERIES IN THE

THERMO-HYGRO TRANSMITTER

The Thermo-Hygro transmitter uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace the
batteries, please follow the steps below:

1. Remove the battery cover with an appropriate screwdriver.

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 because a random security code is assigned by the transmitter at start-up and this
code must be received and stored by the Projection clock in the first 3 minutes of power being supplied
to it

SETTING UP:

1. First, insert the batteries into the Projection clock (see “How to install and replace batteries in
the Projection clock”). Once the batteries are in place, all segments of the LCD will light up

briefly and a short signal tone will sound. Following some test data display, the indoor temperature
and humidity, the time as 0:00 the date as 1.1. and the "weather man" icon will be displayed. If the
indoor temperature and humidity are not displayed after 30 seconds, remove the batteries and
wait for at least 10 seconds before reinserting them. Once the indoor data is displayed proceed to
step 2.

43

44

2. Within 3 minutes of activating the Projection clock, place the batteries into the transmitter (see
“How to install and replace batteries in the Thermo-Hygro outdoor transmitter“).

3. After inserting the batteries into the transmitter, the Projection clock will start receiving data from
the transmitter. The outdoor temperature and humidity should then be displayed on the Projection
clock. If this does not happen after 15 minutes, the batteries will need to be removed from both
units and reset from step 1.

4. The Projection clock can take up to 3 remote transmitters. If you have purchased additional
transmitters, follow step 2 for all extra transmitters. However, ensure that you leave 10 seconds in
between the reception of the last transmitter and the set-up of the following transmitter. The
Projection clock will number the transmitters in the order of set-up, i.e. the first transmitter will
have the temperature and humidity displayed with the number 1 against it and so on.

5. Before all the transmitters are set up, there is a testing period, during which the display switches
quickly between all the received transmitters at random, according to which random transmission
it receives. Pressing any key will stop this process. The process also stops automatically if up to 3
transmitters are received or no keys are pressed for a few minutes.

6. Once the remote temperature and humidity have been received and displayed on the Projection
clock, the DCF-77 time code reception is automatically started. This takes typically between 3-5
minutes in good conditions. This time period is an excellent opportunity to locate the transmitter(s)
in suitable location(s) outdoors. In order to ensure sufficient 433 MHz transmission however, this
should under good conditions be no more than 100 meters from where the Projection clock will be
finally positioned (see notes on “Positioning the thermo-hygro transmitter” and “433 MHz
Reception”).

7. If after 10 minutes, the DCF time has not been received, use the SET key to manually enter a time
initially The clock will automatically attempt to receive the DCF time at each full hour. When this is
successful, the received time will override the manually set time. The date is also updated with the

received time. (Please refer also to notes on “DCF-77 Radio controlled Time” and “Manual
Time Setting”).

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 authorised depot.

PROJECTION OF TIME AND/OR REMOTE TEMPERATURE

1. When plugged into an AC outlet, the projection clock can continuously project the time and/or

remote temperature.

2. When operating on batteries alone, the projection clock will only project when SNOOZE/LIGHT

button is pressed.

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 default is projecting time (Hour and Minutes). The Projection Alarm can be set to project the

time (M0), remote temperature of Channel 1 (M1), or alternating between time and remote
temperature (M2) by pressing and releasing the “DISPLAY” button. The selected display mode
will flash on the lower middle as “M0”, “M1” or “M2”.

5. The direction of the display can also be rotated 360 in 90 increments by pressing the

45

directional button. There is no display on the LCD that signifies the direction.

6. The projector case can be tilted for about 60 to help to orient the projected data.

A signal reception symbol in the upper center indicates that a signal is received from the

transmitter(s).

DCF-77 RADIO CONTROLLED TIME:

The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch
Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in one
million years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal
DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Your radio-controlled
Projection clock receives this signal and converts it to show the precise time in summer or wintertime.
The quality of the reception depends greatly on the geographic location. In normal cases, there should
be no reception problems within a 1,500 km radius around Frankfurt.

Once the outdoor temperature and humidity are displayed on the Projection clock after initial set-up, the
DCF tower icon in the clock display will start flashing in the upper left corner. This indicates that the
clock has detected that there is a radio signal present and is trying to receive it. When the time code is
received, the DCF tower becomes permanently lit and the time will be displayed.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then please
take note of the following:

54

Recommended distance to any interfering sources like computer monitors or TV sets is a

minimum of 1.5 - 2 metres.

Within ferro-concrete rooms (basements, superstructures), the received signal is naturally

weakened. In extreme cases, please place the unit close to a window and/or point its front or back
towards the Frankfurt transmitter.

During nighttime, the atmospheric disturbances are usually less severe and reception is possible

in most cases. A single daily reception is adequate to keep the accuracy deviation below 1
second.

WEATHER FORECAST AND TENDENCY:
The weather forecast icons (Weather man):

One of the 24 different weather icons (featured by Weather man with different clothing) is displayed in
the centre of LCD, which indicate the different forecast weather condition due to air pressure level
(Sunny, Sunny + Cloudy or Cloudy + Rainy) and the current outdoor temperature (Temperature value
detected by Transmitter channel 1):

Sunny

and

and

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

65

66

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 Projection clock 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 Projection
clock has been designed for use in. In areas that experience sudden changes in weather (for example
from sunny to rain), the Projection 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 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), remove the batteries and re­insert them after about 30 seconds. By doing this, the Projection 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. Again,
disregard weather forecasts for the next 12 to 24 hours as this will allow time for operation at a constant
altitude.

THE WEATHER TENDENCY INDICATOR

Working together with the weather icons are the weather tendency indicators (the upward and
downward arrows located on the right hand side of the weather man icon). 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.

Therefore, user may see how the weather has changed and is expected to change. For example, if the
indicator is pointing downwards together with cloudy icons, it means that the last noticeable change in
the weather was when it was sunny (the sunny icon only). Therefore, the next change in the weather will
be the cloudy icons since the indicator is pointing downwards.

67

Note:

Once the weather tendency indicator has registered a change in air pressure, it will remain permanently
visualized on the LCD.

INDOOR TEMPERATURE AND HUMIDITY READING:

The indoor temperature and humidity are measured automatically and displayed on the fourth section of

THERMO-HYGRO TRANSMITTER:

The range of the Thermo-Hygro transmitter may be affected by the temperature. At cold temperatures
the transmitting distance may be decreased. Please bear this in mind when placing the transmitter.

433MHz RECEPTION

The Projection clock should receive the temperature and humidity data within 15 minutes after set-up. If
the temperature and humidity data is not being received 15 minutes after setting up (the display shows “-

- -” after checking for the transmission 3 times) please check the following points:

1. The distance of the projection clock or transmitter should be at least 1.5 to 2 meters away from

any interfering sources such as computer monitors or TV sets.

2. Avoid positioning the Projection clock onto or in the immediate proximity of metal window frames.

3. Using other electrical products such as headphones or speakers operating on the same signal

frequency (433MHz) may prevent correct signal transmission and reception.

4. Neighbours using electrical devices operating on the 433MHz signal frequency can also cause

interference.

Note:

When the 433MHz signal is received correctly, do not re-open the battery cover of either the transmitter
or Projection clock, 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 about 100 m from the transmitter to the Projection clock (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).

POSITIONING THE THERMO-HYGRO TRANSMITTER:

The Thermo-hygro transmitter can be placed onto any flat surface or wall mount using the bracket which
doubles as a stand or wall mount base.

To wall mount:

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

71

2. Clip the transmitter onto the bracket.

Note:

Before permanently fixing the transmitter wall base, place 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,
