3. Setup and Installation
3.1 Mounting Options
Proper measurement is crucial for correct installation. Please refer to the diagrams below for guidance.
Inside Mount
- The window depth must be at least 2.5 inches (2½").
- Measure the width of the window frame at three points (top, middle, bottom). Select the smallest measurement as the shade width.
- Measure the height of the window frame at three points (left, middle, right). Select the largest measurement as the shade height.
- The actual blind's size will be the ordered size.
Outside Mount
- For outside mount, add 4 inches to both the window width and height measurements to determine the required shade size.
- This method helps eliminate light gaps on the sides for full blackout coverage.
- The actual width of the blinds should be the maximum window size plus 4 inches.

The inside mount diagram shows measuring window width and height, emphasizing a minimum 2.5-inch depth. The outside mount diagram shows adding 4 inches to both width and height for optimal coverage.

Image 3.2: An illustration showing the maximum dimensions for the automatic blinds. Blinds can be up to 58 inches wide and can stop at up to 72 inches in height. Adjustable stop points less than 72 inches are possible via remote control.
3.2 Solar Panel Connection
The motorized blinds come with a complimentary solar panel. It is recommended to keep the solar panel plugged into the smart roller shades at all times to ensure continuous power supply. This eliminates the need for frequent battery replacements.
Alternatively, the blinds can be charged using an external power supply with a 1A charger.
4. Operating Instructions
4.1 Remote Control
The 15-channel remote control allows you to manage up to 15 motorized blinds simultaneously. Each channel can be programmed to control a single shade or a group of shades. Refer to the remote control's specific instructions for pairing and programming.
4.2 Smart Control (Optional Hub Required)
For advanced smart controls, including voice and app integration, a DONGFXK smart hub (smart bridge) is required. The hub can control up to 30 automatic blackout shades. The hub is available separately from DONGFXK. Once connected, you can integrate your shades with compatible smart home systems.
4.3 Adjusting Shade Height
The smart shades can be freely adjusted to any height between 0 and 72 inches. Use the remote control or smart app to set desired upper and lower limits, or to move the shade to any intermediate position.

5. Maintenance
5.1 Fabric Care
Due to the unique properties of the fabric, wrinkles may form during transportation. To remove wrinkles, you can gently iron the fabric for a brief moment (one second) upon receiving the blinds, or allow them to hang for approximately one week, and the wrinkles should naturally dissipate.
For general cleaning, gently wipe the fabric with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.
6. Troubleshooting
If you encounter any issues with your DONGFXK Motorized Blackout Roller Shades, please consider the following common solutions:
- Shade Not Responding: Check if the solar panel is properly connected and receiving light, or if the internal battery requires charging via the 1A external charger. Ensure the remote control batteries are functional.
- Remote Control Issues: Verify that the remote is paired correctly with the shades. If controlling multiple shades, ensure the correct channel is selected.
- Inconsistent Movement: Check for any obstructions in the shade's path. Ensure the mounting brackets are securely fastened and level.
- Smart Control Connectivity: If using a smart hub, ensure it is powered on, connected to your network, and properly paired with the shades and your smart home app.
For persistent issues, please contact DONGFXK customer support.
