Setup

1. Battery Installation

1. Locate the battery compartment on the back of the alarm clock.
2. Open the battery compartment cover.
3. Insert 2 x AAA (LR03) batteries, ensuring correct polarity (+ and -).
4. Close the battery compartment cover securely.

Upon battery installation, the clock will automatically begin searching for the radio-controlled time signal (DCF-77). This process may take several minutes. Ensure the clock is placed away from sources of interference such as electronic devices or metal objects.

2. Initial Time Synchronization

The WT375 is a radio-controlled clock, meaning it automatically synchronizes its time with a precise atomic clock signal.

• Place the clock near a window for better signal reception.
• The signal reception icon (often a tower or waves) will flash during synchronization.
• Once synchronized, the icon will become solid, and the correct time, date, and day will be displayed.
• If the signal is not received within 24 hours, try relocating the clock.
