Place the clock within reception range of the DCF77 signal for automatic time synchronisation; allow a few minutes for initial reception. If you have the wireless outdoor transmitter, pair or position it according to its instructions so the outdoor temperature is transmitted to the clock. Use the display controls to select automatic multi-colour mode or a single colour and set the preferred brightness level. Set the alarm time and enable snooze as needed. Connect a smartphone to the USB port to charge it overnight.

Recommendations

Position the clock where it receives a clear DCF77 signal (away from large metal objects and strong electromagnetic sources). Place the outdoor transmitter outdoors in a sheltered, ventilated spot to ensure accurate external temperature readings and replace batteries in both units as recommended to maintain reliable operation.
