TO INSTALL AND REPLACE BATTERIES IN THE PROJECTION ALARM

The Projection Alarm uses 2 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 bott om 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.

3

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 (see Notes at below
clause).

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.

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/humidity and the remote temperature will be displayed.
Also, the time will be displayed as 0:00.

6

• 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 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.

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 plugged into an AC outlet, the projection alarm can continuously project

the time

7

2. When operating on batteries alone, the projection alarm will only project when

the SNOOZE button is pressed or the alarm is sounding.

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° increments by pressing the
Projection Direction

button. The proj ector case can be rota ted 180° to further help

orient the projected display.

TOGGLE BETWEEN THE DISPLAY OF INDOOR TEMPERATURE/
HUMIDITY, PRESET ALARM TIME AND CALENDAR

By pressing shortly the MODE/MIN key, user may toggle between the following displays:

1. Indoor temperature and humidity;

2. Preset alarm time;

3. Day and weekday;

4. Month and day

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 1500km radius of Frankfurt.

Once the outdoor reception test period is completed, 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 m eters.

• 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 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.

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.

• 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 not 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.

21

• 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.
