Package Contents
Please check that all items are present in the package:
- Karlsson Natural Cuckoo Clock (Model KA5886GR)
- User Manual (this document)
Note: Batteries are not included and must be purchased separately.
Setup
1. Battery Installation
- Locate the battery compartments on the back of the clock.
- Insert one AA battery for the clock mechanism and two LR14 (C-cell) batteries for the cuckoo mechanism, ensuring correct polarity (+/-) as indicated inside the compartments.
- Close the battery compartment covers securely.
2. Initial Time Setting
- First, set the clock to 6:00 AM. Allow the cuckoo to chime the corresponding number of times. If it does not chime, ensure batteries are correctly installed and the room is not completely dark.
- Advance the time clockwise using the adjustment knob on the back of the clock to the current hour. The cuckoo will chime for each hour passed. For PM hours, continue advancing past 12:00 PM until the correct PM hour is reached. For example, to set 3:00 PM, advance past 12:00 PM, then 1:00 PM, 2:00 PM, and finally 3:00 PM.
- Once the hour is set, adjust the minute hand to the correct minute.
- If the cuckoo chimes incorrectly after setting (e.g., chimes 3 times at 2:00), use the 'SET' button (if present) on the back of the clock. Pressing this button will advance the cuckoo count forward by one hour per press until it matches the current hour.

Operating Instructions
Cuckoo Mechanism
The Karlsson Natural Cuckoo Clock features an hourly cuckoo chime. At the top of each hour, a bird sound will play, followed by the cuckoo chiming the corresponding number of times for the hour (e.g., one chime at 1:00, twelve chimes at 12:00).
The cuckoo mechanism is designed to be silent during nighttime hours (typically 10:00 PM to 5:00 AM) to prevent disturbance. This feature is automatic and relies on a light sensor; ensure the clock is in a location where it experiences natural light and darkness cycles for optimal performance.

Maintenance
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 wood finish or clock mechanism. Ensure no liquid enters the clock's internal components.
Battery Replacement
When the clock hands slow down or the cuckoo mechanism stops chiming, it is time to replace the batteries. Follow the battery installation steps outlined in the 'Setup' section. Always replace all batteries at the same time with new ones of the specified type.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock hands are not moving or are slow. | Low or dead AA battery for the clock mechanism. | Replace the AA battery with a new one, ensuring correct polarity. |
| Cuckoo does not chime or chimes incorrectly. | Low or dead LR14 batteries for the cuckoo mechanism; Incorrect time setting; Cuckoo mechanism obstruction. | Replace LR14 batteries. Re-set the time following the 'Initial Time Setting' instructions. Gently check for any obstructions around the cuckoo bird opening. If the cuckoo count is off, use the 'SET' button to adjust. |
| Cuckoo chimes at night. | Clock's internal light sensor is obstructed or in a brightly lit room, preventing it from detecting darkness. | Ensure the clock is in a location where it experiences natural light and darkness cycles. Avoid placing it under direct artificial light at night. |
| Clock loses time or gains time. | Weak battery; Extreme temperature fluctuations. | Replace the AA battery. Ensure the clock is placed in a stable room temperature environment. |
