SETTING UP :
The projection clock can be batteries operated or powered by the provided
AC/DC adapter.
POWER SUPPLY :
The Projection Clock uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the
batteries, please follow the steps below:
1. Lift up and remove the battery
compartment cover.
2. Insert batteries observing the correct
polarity (see marking).
3. Replace compartment cover.
Note: User shall also refer to Manual Setting for detailed Setting up procedures.
32

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
Note: User shall also refer to Manual Setting for detailed Setting up procedures.

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 transformer.
Otherwise your projection clock may be damaged.
•Radio controlled time receiver is at the bottom side of the main unit. Don’t place
the adapter wire adjacent to the bottom side of the main unit when AC power is
used, as this may decrease the reception sensitivity.

BATTERIES 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.
Notes:
•After the projection clock is powered, there will be a beep sound and the LCD
(Liquid Crystal Display) will activate.
•The indoor temperature and the time as 0 :00 will be displayed.
•The DCF time reception will automatically be initiated, and a tower icon will
appear (no tower icon will appear if the time reception is too weak to be detected,
and the time display will start from 0:00).
•When DCF time has not been received, user may use the MODE/MIN key to
manually enter a time and date 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”).
TO RESET THE PROJECTION CLOCK
To reset the Projection clock to the factory default setting or in case of a malfunction,
please remove all batteries from the unit and unplug the AC/DC adapter from any
power source. Wait at least for 3 minutes before powering up the Projection clock
again.
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure optimum
accuracy of these units. (Battery life –see Specifications)
Please participate in the preservation of the environment. Return
used batteries to an authorized depot.

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 1500km radius of Frankfurt.
The DCF tower icon in the clock display will start flashing in the upper center. 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:

•Recommended distance to any interfering sources like computer monitors or TV
sets is a minimum of 1.5 - 2 meters.
•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.

MANUAL SETTING
Time zone setting
User shall first remove all the batteries from the projection clock and wait for 3 minutes.
Then user shall press and hold the MODE/MIN key and at the same time place the
batteries into the clock. Then there will be a beep sound and the flashing time zone
digits "0 h" will be displayed. User may now press shortly the MODE/MIN key to set the
time zone between +9 and -9 hours (The time zone default of the Projection clock is “0
hour”).

Then confirm with the SNOOZE key and enter the Manual time setting.
Note: If AC adaptor is used instead of battery, user shall first connect the adaptor to the
wall socket, then press and hold the MODE/MIN key and finally insert the power cable
to the jack of the clock. User shall keep on holding the MODE/MIN key until the time
zone flashing digit "0h" is displayed on LCD. Then he may go on the manual setting.
Manual time setting
In case the Projection clock cannot detect the DCF-signal (for example due to
disturbances, transmitting distance, etc.), the time can be manually set. The clock will
then work as a normal Quartz clock.

1. The hour and the minute digits will start flashing.
2. Use the AL/HOUR key to set the hour; MODE/MIN key to set the minute.
3. Confirm with the SNOOZE key and enter the Calendar setting.
Note:
•The unit will still try and receive the signal every one hour despite it being
manually set. When it does receive the signal, it will change the manually set time
into the received time. Also the manually-set date and weekday will be changed to
the received date.
•The time is displayed in 24-hour format.
CALENDAR SETTING :
The date default of the Projection clock is 1. 1. in the year 2005. Once the radio-
controlled time signals are received, the date is automatically updated. However, if the
signals are not received, the date can also be set manually.
1. The year digits start flashing. Use the MODE/MIN key to set the year (the range
runs from 2000 to 2049).

PROJECTION OF TIME
Note:
The projection is a red light, not harmful under normal usage, yet care should be taken
to avoid looking directly into the light.
1. When the radio-controlled projection clock is plugged with an AC/DC
adaptater, the clock will continuously be projected
2. If the radio-controlled projection clock is only working with batteries, the time
will be only projected when the SNOOZE key will be pressed
3. The projection will auto-focus for display from about 1.7 to 2.0 meter away. A
dark surrounding will be necessary to clearly see the projection.

The direction of the display can also be rotated 360°in 90°rotations by pressing the
Projection Direction button. The projector case can be rotated 180°to further help
orient the projected display.
TOGGLE BETWEEN THE DISPLAY OF INDOOR TEMPERATURE, PRESET ALARM
TIME AND CALENDAR :
By pressing shortly the MODE/MIN key, you can toggle between the following displays:
