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.

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:
