Setup

1. Battery Installation

1. Locate the battery compartment cover on the back of the alarm clock.
2. Remove the cover by sliding it down or pressing the latch.
3. Insert 2 new AAA batteries, ensuring the correct polarity (+ and -) as indicated inside the compartment.
4. Replace the battery compartment cover.

2. Initial Setup and Radio Control (DCF 77)

Upon battery insertion, the alarm clock will automatically attempt to synchronize with the DCF 77 radio signal. This process ensures the time, date, and day are set accurately, including automatic adjustment for daylight saving time.

• Place the alarm clock near a window for optimal signal reception.
• The radio signal icon (often a tower with waves) on the display will flash during synchronization.
• Once synchronized, the icon will become solid, and the correct time and date will be displayed. This process may take several minutes.

The radio control (DCF77) feature automatically sets the correct time and adjusts for seasonal changes.

3. Time Zone Setting

If you are in a different time zone than the DCF 77 signal (Central European Time), you can adjust the time zone offset:

• Refer to the buttons on the back or side of the clock. Typically, a button labeled 'TIME ZONE' or similar is used.
• Press this button to cycle through time zone offsets (e.g., +1, -1 hour).
• The display will show the adjusted time.

4. Manual Time Setting (If Radio Signal Unavailable)

In areas without a radio signal, the time can be set manually:

• Press and hold the 'SET' or 'MODE' button until the time digits begin to flash.
• Use the '+' or '-' buttons (often labeled 'UP' and 'DOWN' or arrow keys) to adjust the hours.
• Press 'SET' or 'MODE' again to move to minutes, then adjust.
• Continue pressing 'SET' or 'MODE' to set the year, month, and day if necessary.
• Press 'SET' or 'MODE' one last time to confirm and exit manual setting mode.
