4. Radio technology

Radio technology is the most modern form of time

transmission. With good reception, a radio-controlled

clock keeps very precise time and need never be reset.

With all radio-controlled clocks a deviation of just

1 second over 1 million years can be expected. The

official German transmitter is in the vicinity of Frankfurt/

Main and transmits via long wave 77,5 kHz within a

radius of approx. 1,500 km.

5. Setting up

Open the hinged battery cover (3) on the rear of the

alarm clock and insert one 1.5V alkaline battery, type

LR 6 (size AA), ensuring that the + and the – are the

right way round. Refit the battery cover.

6. Setting the time automatically

After that, the receiver is switched off. During the

reception phase, lasting approx. 2 minutes, the hands

stay at the 12 o'clock position. The entire procedure for

setting the hands to exact time takes up to 9 minutes.

7. Setting the alarm time

To set the alarm time you require, turn the adjusting

knob (2) on the back of the alarm clock in the direction

indicated by the arrow. If you turn the knob in the oppo-

site direction this will not always adjust the alarm hand.

To activate the alarm function, push the side-mounted

switch (1) upwards towards the bell symbol.

8. Switching off the alarm time signal

To deactivate the alarm function completely, press the

side-mounted switch-off button (1) down.
