3. Safety Information
To ensure safe operation and prevent damage, please observe the following:
- Do not expose the clock to direct sunlight, extreme temperatures, or high humidity.
- Keep the clock away from strong magnetic fields, which may interfere with its operation.
- Use only the specified battery type (AA alkaline). Do not mix old and new batteries or different battery types.
- Dispose of used batteries according to local regulations.
- Do not attempt to disassemble or repair the clock yourself. Contact qualified service personnel.
- Ensure the clock is securely mounted on the wall to prevent falling.
4. Setup
4.1 Battery Installation
- Locate the battery compartment on the back of the clock (refer to Figure 2).
- Open the battery compartment cover.
- Insert one (1) AA alkaline battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
4.2 Initial Time Synchronization
After battery installation, the clock will automatically attempt to receive a radio time signal. This process may take several minutes.
- Place the clock in a location where it can receive a clear radio signal. Avoid placing it near large metal objects, electronic devices, or in basements.
- The clock hands will move to the 12 o'clock position and then begin searching for the time signal.
- Once the signal is received, the clock will automatically set itself to the correct time. This typically occurs within 5-10 minutes, but can take longer depending on signal strength.
- If the clock does not set itself after an extended period, try moving it to a different location or manually setting the time (refer to Section 5.1 for manual setting).

5. Operation
5.1 Radio-Controlled Timekeeping
Your RHYTHM Citizen clock is designed to automatically synchronize with official time signals, ensuring accurate time display without manual adjustment. The clock will periodically attempt to receive the signal, typically overnight, to correct any minor discrepancies.
In areas with poor reception, or if you need to set the time manually (e.g., after a long period without power), there may be a manual setting button or procedure. Refer to the specific instructions on the clock's movement or a detailed diagram if provided with your physical product.
5.2 Continuous Second Hand
The clock features a continuous (sweeping) second hand, which moves smoothly around the dial rather than in distinct ticks. This design provides quiet operation, ideal for bedrooms or quiet environments.

6. Maintenance
6.1 Cleaning
To clean the clock, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish or internal components.
6.2 Battery Replacement
The clock is equipped with a battery replacement notification function. When the battery power is low, the clock's operation may become erratic, or the second hand might stop. Replace the AA alkaline battery promptly when this occurs to ensure continuous and accurate timekeeping. Refer to Section 4.1 for battery installation instructions.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not receiving radio signal / Incorrect time. | Poor reception area, interference, initial setup incomplete. | Move the clock to a different location, away from electronics or metal objects. Allow more time for synchronization. Ensure battery is fresh. |
| Second hand stops or moves erratically. | Low battery power. | Replace the AA alkaline battery with a new one. |
| Clock not functioning after battery installation. | Incorrect battery polarity, faulty battery, damaged movement. | Check battery polarity. Try a new battery. If problem persists, contact customer support. |
