Luminous Hands and Markers
The clock features luminous hands and hour markers that glow in the dark after exposure to light. The intensity and duration of the glow depend on the amount and type of light exposure. For optimal visibility in darkness, expose the clock face to a bright light source before use.
Maintenance
Battery Replacement
When the clock hands slow down or the alarm sound weakens, it is time to replace the battery. Follow the battery installation steps outlined in the "Setup" section.
Cleaning
To clean the clock, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the casing or internal components. Avoid exposing the clock to excessive moisture.
Troubleshooting
| Problem | Possible Cause | Solution |
