Adjust the display tilt angle in that way, that the marking of the tilt mechanism indicates “Travelling clock mode”. Press and hold the START-button and the MEM-button simultaneously for at least approx. 1 second. Then you can adjust the time display format (12 or 24 hours display) with the MEM-button. Press the SNOOZE-button to continue with the adjustment of the year value. Follow the same steps to enter the correct values for year, month and day, hour, minute and time. Date and time are now displayed constantly. You may leave the setting mode at any time by pressing the START-button.
If the batteries are removed, these values are lost and need to be input again.
