1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your Grundig RGB LED Light Strip, Model 22235. This 3-meter self-adhesive LED strip features 180 high-performance SMD 3528 LEDs, offering a wide range of RGB colors and dynamic lighting effects controlled by an included remote. Designed for both indoor and outdoor use (IP65 rated), it allows for flexible and decorative lighting solutions.
Please read this manual thoroughly before using the product to ensure safe and optimal performance.
2. Safety Instructions
- Ensure the power supply is disconnected before installation or maintenance.
- Do not expose the LED strip or power supply to extreme temperatures or direct sunlight for prolonged periods.
- Avoid bending the LED strip sharply, as this may damage the internal circuitry.
- Do not cut the LED strip at any point other than the designated cutting marks. Cutting elsewhere will damage the strip and void the warranty.
- Keep the remote control battery (CR 2035) away from children. If swallowed, seek immediate medical attention.
- This product is rated IP65, meaning it is protected against dust ingress and low-pressure water jets from any direction. It is suitable for outdoor use but should not be submerged in water.
- Use only the provided power adapter. Using an incompatible adapter may damage the product or pose a safety risk.

4. Setup and Installation
- Prepare the Surface: Clean the desired installation surface thoroughly. Ensure it is dry, smooth, and free of dust, oil, or grease for optimal adhesion.
- Measure and Cut (Optional): If a shorter length is required, locate the designated cutting marks on the LED strip. These are typically indicated by a copper pad and a scissor icon. Cut only at these marks. Warning: Cutting at any other point will damage the strip permanently.
- Apply the LED Strip: Carefully peel off the protective backing from the adhesive tape on the back of the LED strip. Press the strip firmly onto the prepared surface, ensuring even contact along its entire length.
- Connect the Power Adapter: Connect the LED strip's connector to the power adapter's output. Then, plug the power adapter into a standard electrical outlet (220-240V).
- Remote Control Battery: The remote control comes with a pre-installed CR 2035 button cell battery. If the remote does not respond, check if the battery tab needs to be removed or if the battery needs replacement.
5. Operating Instructions
The Grundig RGB LED Light Strip is controlled using the included infrared remote control. Ensure the remote is pointed towards the receiver on the LED strip's power cable for proper function.

- SMOOTH: Gradually changes between colors.
6. Maintenance
- Cleaning: Ensure the power is off and unplugged before cleaning. Gently wipe the LED strip with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Remote Control Battery Replacement: If the remote control stops responding, the CR 2035 button cell battery may need replacement. Open the battery compartment on the back of the remote, remove the old battery, and insert a new one with the correct polarity (+ side up).
- Storage: If storing the LED strip for an extended period, ensure it is clean and dry. Store it in a cool, dry place away from direct sunlight.
