Setup
Battery Installation
The clock is powered by one No. 1 (D-cell) battery. It is recommended to use carbon batteries instead of alkaline batteries, as alkaline batteries can reduce the lifespan of the clock. The battery life is approximately 5-6 months.
- Open the back cover of the battery compartment.
- Insert one No. 1 (D-cell) battery, ensuring correct polarity.
- Close the battery compartment cover securely.

Image: Battery installation steps. This image illustrates opening the battery compartment, inserting the D-cell battery, and closing the cover. Note: Before inserting the battery, adjust the clock forward by 1 minute, as the battery will produce current 1 minute after insertion.
Operating Instructions
Setting the Time
To set the time, follow these steps:
- Adjust the time in hours/minutes by rotating the minute and time zone right rotation button counter-clockwise.
- The hour page cannot be adjusted directly; only the minute page can be used for time adjustment.
- The time adjustment needs to be advanced by 1 minute because it takes one minute for the battery to fully generate current inside.
- The time adjustment knob should be turned from back to front and cannot be turned in the opposite direction.
- Do not manually move the area marked in red circle (refer to image below), as it may affect the accuracy of the clock's timing.

Image: Time adjustment explanation. This image shows the sequence of adjusting the minute display to set the correct time. The adjustment button is on the left flip mechanism and should be turned counter-clockwise.

Image: Instructions for use. This image provides a visual summary of battery installation, time adjustment (rotating the right knob counter-clockwise), the correct direction for the time adjustment knob (back to front), and a warning against manually moving the internal mechanism.
Automatic Time Flipping
The clock automatically flips pages every minute and hour, providing a continuous display of the current time. There may be a slight error of up to 2 minutes in the initial synchronization, which is normal.

Maintenance
- Cleaning: Wipe the clock with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as they may damage the surface.
- Battery Replacement: Replace the D-cell battery every 5-6 months, or when the clock's operation becomes inconsistent. Always use carbon batteries for optimal performance and clock longevity.
- Storage: If storing the clock for an extended period, remove the battery to prevent leakage.
Troubleshooting
