To clean the alarm clock, gently wipe the surface with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or chemical sprays, as these may damage the finish or internal components.
4.2 Remplacement de la batterie
When the clock begins to lose time or the alarm function weakens, it is an indication that the battery needs to be replaced. Follow the steps in Section 2.1 for battery installation. Always use a fresh AA battery for optimal performance.

Ensure the alarm ON/OFF switch is in the "ON" position. Verify that the alarm hand is set to the desired time. Check the battery as a weak battery can affect alarm volume.
