Увод
This manual provides detailed instructions for the setup, operation, and maintenance of your Youshiko YK YC8025-B Radio Controlled Wall Clock. This clock is designed for precise timekeeping, automatically adjusting for seasonal changes and receiving time signals specific to the UK and Ireland (MSF).
The clock features a large LCD display showing time in 12/24 hour format, date, month, day of the week, indoor temperature (Celsius or Fahrenheit), and moon phase. It also includes an alarm with a snooze function.

2. Почетни пријем сигнала
After battery installation, the clock will automatically begin searching for the radio time signal. This clock is designed for the UK and Ireland (MSF signal).
- Place the clock near a window or in an open area to optimize signal reception.
- The signal reception icon (often a tower with waves) on the display will flash during the search.
- Once the signal is successfully received, the clock will automatically set the correct time, date, and day, and the signal icon will become solid. This process may take several minutes.
Note: For optimal signal reception, avoid placing the clock near electronic devices that may cause interference.

Одржавање
1. Замена батерије
When the display becomes dim or the clock stops functioning, it is time to replace the batteries.
- Отворите одељак за батерије на полеђини сата.
- Уклоните старе батерије.
- Уметните нове батерије, водећи рачуна о исправном поларитету.
- Close the battery compartment. The clock will then attempt to re-synchronize with the radio signal.
2. Чишћење
