Start-up

• Open the battery compartment and insert the batteries (2 x 1,5 V AA), polarity as illu-

strated. The unit is now ready to use.

Radio Controlled Clock

• After start-up the clock will scan the DCF time signal ("

while scanning for DCF unless they are well received or stopped manually.

• The clock automatically scans the time signal at 3.00 a.m. everyday to maintain accurate

timing. For failed reception, scanning stops and repeats again at 4.00 a.m. 5.00 a.m. and

6.00 a.m.

• The clock manually scans the DCF time signal by holding "+(12/24)"- button and "-(C/F)"-

button for 3 seconds. For failed reception, scanning stops and repeats again the next

4 clock hours.

• Press "+(12/24)"- button and "-(C/F)"- button" again to stop scanning.

• In case the clock cannot detect the DCF-signal (for example due to disturbances, transmit-

ting distance, etc.), the time can be set manually. The clock will then work as a normal

quartz clock. (see "Manual setting of clock and calendar").

• The time base for the radio controlled time is a Caesium Atomic Clock operated by the

flingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting

range of approximately 1,500 km. Your radio-controlled alarm 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.

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 metres.
