3. Operating Instructions
Once the battery is installed and the time is set, your Infinity Instruments wall clock will begin operating automatically. The silent sweep movement ensures that the second hand moves continuously without producing any ticking sounds, making it ideal for quiet environments.
4. Maintenance
4.1 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 may damage the finish or the shatter-resistant lens.
4.2 Battery Replacement
Replace the AA battery annually or when the clock begins to lose time or stop functioning. Follow the battery installation steps outlined in Section 2.1.
5. Troubleshooting
- Clock Not Running: Ensure the battery is inserted correctly with the proper polarity. Replace with a fresh AA battery if necessary.
- Clock Losing Time: This typically indicates a low battery. Replace the AA battery with a new one.
- Hands Getting Stuck: Check if the hands are bent or obstructed. Gently adjust them if possible, ensuring they do not touch each other or the clock face. If the issue persists after battery replacement, the internal mechanism may require professional inspection.
