1. Introduction
The Karlsson Duo Cuckoo Wall Clock is a modern timepiece that combines a robust design with the playful elements of a classic cuckoo clock. Each hour, a small bird emerges, emitting gentle forest sounds. This manual provides essential information for the proper installation, operation, and care of your clock.
2. Setup
2.1 Unpacking
Carefully remove all components from the packaging. Ensure the clock is free from any protective materials.
2.2 Battery Installation
- Locate the battery compartments on the back of the clock.
- Insert 3 AA batteries (not supplied) into the designated slots, ensuring correct polarity (+/-).
- Close the battery compartment covers securely.

This image displays the rear of the Karlsson Duo Cuckoo Wall Clock. Two circular sections are visible, each containing a battery compartment. The left section shows an open compartment for AA batteries, with a red button for adjustments. The right section shows a closed compartment. Both sections have mounting holes at the top.
2.3 Wall Mounting
The clock is designed for wall mounting. Due to its weight (620g) and dimensions (27.9 x 3.81 x 16.5 cm), ensure you use appropriate wall anchors and screws suitable for your wall type to securely hang the clock.

The left section displays the clock face with black hands and the 'KARLSSON' logo. The right section features a small opening with a golden rim, from which a white cuckoo bird is visible.
3. Operating Instructions
3.1 Setting the Time
To set the time, gently turn the adjustment knob located on the back of the clock (often a small wheel or button near the clock mechanism) until the hands indicate the correct time. Avoid moving the hands directly.
3.2 Cuckoo Function
- The cuckoo bird will emerge and emit gentle forest sounds every hour.
- The clock features a light sensor that automatically silences the cuckoo function in low-light conditions to prevent disturbance during the night.
- Volume control: The clock offers three volume settings for the cuckoo sound. Adjust this using the dedicated switch or button on the back of the clock.
- Chiming schedule: You can select specific hours for the cuckoo to start and stop chiming, allowing for customization of its operation. Refer to the controls on the back of the clock for these settings.

3.3 Silent Movement
The clock is equipped with a silent sweep movement, ensuring no ticking sounds for a peaceful environment.
4. Maintenance
- Cleaning: To clean the clock, use a soft, dry cloth. Avoid abrasive cleaners or solvents, as these may damage the finish.
- Battery Replacement: Replace batteries promptly when the clock's performance diminishes or the cuckoo function becomes inconsistent. Always replace all batteries at once with new ones of the same type.
5. Troubleshooting
- Clock Not Working: Check if the batteries are inserted correctly and are not depleted. Replace if necessary.
- Cuckoo Not Sounding: Ensure the batteries are fresh. Verify that the light sensor is not detecting darkness (if it's daytime). Check the volume setting.
- Incorrect Time: Re-adjust the time using the setting knob on the back of the clock.
