5.2 Time Setting
- After installing batteries, locate the time setting knob on the back of the clock mechanism.
- Gently turn the knob to move the clock hands clockwise until the correct time is displayed.
- Avoid turning the hands counter-clockwise, as this may damage the movement.
5.3 Mounting and Placement
The Karlsson Duo Cuckoo Clock can be used as a wall-mounted clock or placed on a tabletop.
- Wall Mounting: Use the integrated hanging slots on the back of each clock unit. Ensure the wall fasteners (screws or hooks, not included) are appropriate for the clock's weight (0.62 kg) and wall material. Hang both units side-by-side.
- Tabletop Placement: Place the clock on a stable, flat surface. Ensure it is not prone to falling or being knocked over.
6. Operating the Clock
6.1 Analog Time Display
The clock features a sweep movement, providing a smooth, continuous motion of the second hand (if present) and quiet operation.
6.2 Cuckoo Function
The cuckoo bird will emerge from its compartment and make soft forest sounds every hour on the hour. This feature operates automatically once batteries are installed and the time is set.

7. Maintenance
7.1 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.

When the clock hands slow down, stop moving, or the cuckoo function becomes irregular, it is time to replace the batteries. Follow the instructions in Section 5.1 for battery installation.
8. Troubleshooting
- Clock not working: Check if batteries are inserted correctly with the right polarity. Ensure batteries are fresh.
- Cuckoo not sounding: Verify batteries are fresh and correctly installed. Ensure the clock is set to the correct time. The cuckoo sounds hourly.
- Incorrect time: Adjust the time using the setting knob on the back of the clock.
