Introduction
Thank you for choosing Joydeco 100% Blackout Roller Shades (Pro). These cordless blinds are designed to provide complete light blockage, UV protection, and thermal insulation for your home or office. Featuring a free-stop system and an upgraded valance design, they offer both functionality and aesthetic appeal. This manual provides detailed instructions for proper installation, operation, maintenance, and troubleshooting to ensure optimal performance and longevity of your shades.
Product Features
- 100% Blackout: Constructed from 100% polyester material with a reinforced thermal insulation coating. These fabrics are soft, smooth, burr-free, wear-resistant, and easy to clean. They effectively block 100% of sunlight and UV rays.
- Thermal Insulation: The thermal backing reduces heat loss and cold transfer through windows, contributing to lower energy bills in both winter and summer.
- Free-Stop Cordless System: Designed for safety, especially around children and pets, by eliminating cords. The robust spring-loaded mechanism has passed 5,000 lift and pull tests, allowing the shade to stop smoothly at any desired position.
- Upgraded Valance Design: The valance is crafted from high-quality aluminum alloy, coordinating with the fabric color for a clean and elegant appearance. It utilizes a 38mm roll tube, which is thicker than standard roller blinds, ensuring a smoother pull. The baffle plate design conceals the roller shutter mechanism and prevents dust accumulation.
Measuring Your Window
Accurate measurements are crucial for proper fit and function. Please follow these guidelines:
- Inside Mount: For shades mounted inside the window frame, ensure your window depth is at least 2 inches. The blind width should be the window width minus 1/4 inch. The blind height should be greater than or equal to the window height.
- Outside Mount: For shades mounted outside the window frame, the blind width needs to be 4 inches wider than the window width to ensure complete window coverage. The blind height should be the window height plus 4 inches.
Note: A tiny light gap will exist on each side with inside mount. For 100% blackout, an outside mount is recommended.

Installation Instructions
The installation process is designed to be hassle-free. Follow these steps for a straightforward setup:
- Prepare the Window: Ensure the window frame or wall surface where the shade will be mounted is clean and clear of obstructions.
- Mark Bracket Positions: Hold the shade in the desired mounting position (inside or outside mount) and mark the locations for the two brackets. Ensure the marks are level and spaced correctly to support the shade.
- Install Brackets: Using the provided screws and wall anchors (if necessary for drywall), securely fasten the two brackets to the marked positions.
- Attach the Shade: Align the roller shade with the installed brackets. Gently push the shade into the brackets until it clicks securely into place. Ensure both ends are properly engaged.

Operating Instructions
Your Joydeco Roller Shade features a cordless free-stop system for easy and safe operation:

- To Raise the Shade: Gently push up on the bottom rail of the shade. The shade will retract upwards. Release the bottom rail at your desired height, and the free-stop mechanism will hold it in place.
- Smooth Movement: Always operate the shade with a smooth, even motion to ensure the longevity of the spring mechanism. Avoid sudden jerks or excessive force.

Maintenance
To keep your Joydeco Roller Shades in excellent condition, follow these simple maintenance tips:
- Cleaning: For light dust, use a soft brush or vacuum cleaner with a brush attachment. For spots or stains, gently wipe with a damp cloth and mild detergent. Avoid harsh chemicals or abrasive cleaners.
- Mechanism Care: The cordless mechanism is designed for durability. Avoid applying excessive force when raising or lowering the shade. If the mechanism feels stiff, ensure the shade is properly aligned in its brackets.
- Regular Inspection: Periodically check the mounting brackets and hardware to ensure they remain secure.
Troubleshooting
If you encounter any issues with your roller shades, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Shade does not stay in position (falls down or retracts fully) | Spring mechanism issue or improper installation. | Ensure the shade is correctly seated in the brackets. If the issue persists, contact customer support. |
| Shade is difficult to raise or lower | Misalignment or debris in the mechanism. | Check for any obstructions. Ensure the shade is level and not rubbing against the window frame. |
| Light leakage around the edges | Inside mount inherent gap or incorrect measurement. | For minimal light leakage, consider an outside mount with appropriate overlap. Ensure measurements were accurate for your chosen mount type. |
| Shade appears crooked | Uneven bracket installation. | Verify that the mounting brackets are installed perfectly level. Adjust if necessary. |
If these steps do not resolve the issue, please contact Joydeco customer support.
