Operating the Alarm Clock
Turning the Alarm On/Off
- To activate the alarm, slide the alarm ON/OFF switch to the "ON" position.
- To deactivate the alarm, slide the alarm ON/OFF switch to the "OFF" position.
- When the alarm sounds, it will continue until the ON/OFF switch is moved to the "OFF" position.
Silent Movement Feature
The Karlsson KA5784LB is equipped with a silent movement mechanism. This means the second hand moves in a continuous, sweeping motion rather than a traditional ticking step-by-step movement. This feature ensures a quiet environment, ideal for bedrooms or quiet workspaces.

- Battery Replacement: Replace batteries when the clock starts to lose time or the alarm function weakens. Always replace both batteries simultaneously.
- Storage: If storing the clock for an extended period, remove the batteries to prevent leakage.
