WIRELESS 433 MHz PROJECTION CLOCK
Instruction Manual
INTRODUCTION:
Congratulations on purchasing this fancy Projection clock with wireless 433MHz transmission of outdoor
temperature and humidity and display of indoor temperature and humidity. It is further acting as a DCF77 radio controlled clock with date display and two alarms. With the totally 24 different weather forecast
icons featured by "weather man", users can easily observe the forecast weather condition and will no
longer worry the sudden weather change. This innovative product is ideal for use in the home or office.

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.

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.

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.
