1. Introduction
This manual provides detailed instructions for the proper installation and care of your Rainbuvvy replacement wrist strap. This strap is designed for compatibility with DM100 and LEMFO smartwatches that utilize a 32MM strap width. Please read all instructions carefully before proceeding with installation.
2. Package Contents
Verify that all items are present in your package:
- Rainbuvvy 32MM Replacement Wrist Strap (Silicone with Stainless Steel Tang Buckle)
- Disassembly Tool (for strap removal and installation)
3. Installation Instructions
Follow these steps to replace your smartwatch wrist strap:
- Prepare Your Smartwatch: Place your smartwatch face down on a soft, clean surface to prevent scratches.
- Remove the Old Strap:
- Locate the spring bar pins connecting the current strap to the smartwatch casing. These are small metal pins that fit into holes on the watch lugs.
- Using the provided disassembly tool, gently push the spring bar pin inwards from one side.
- While holding the pin in, carefully pull the strap away from the watch casing to release it. Repeat for the other side of the strap and for the second strap piece.
- Attach the New Strap:
- Take one piece of the new Rainbuvvy wrist strap. Insert one end of the spring bar pin into one of the lug holes on the smartwatch casing.
- Using the disassembly tool, push the other end of the spring bar pin inwards. Align the strap with the watch lug and release the pin into the corresponding hole on the other side of the lug.
- Gently tug on the strap to ensure it is securely attached. If it feels loose, repeat the process to ensure the pins are properly seated.
- Repeat these steps for the second piece of the replacement strap.
- Final Check: Ensure both strap pieces are firmly attached and the smartwatch is ready for use.

4. Maintenance and Care
To ensure the longevity and appearance of your wrist strap:
- Cleaning: Wipe the silicone strap regularly with a soft, damp cloth. For deeper cleaning, use mild soap and water, then rinse thoroughly and dry completely before reattaching to your smartwatch.
- Avoid Harsh Chemicals: Do not expose the strap to strong chemicals, solvents, or abrasive cleaners, as these can damage the material.
- Storage: Store the strap in a cool, dry place away from direct sunlight when not in use.
5. Troubleshooting
If you encounter issues during installation:
- Strap Not Attaching Securely: Ensure the spring bar pins are fully compressed and properly aligned with the lug holes before releasing. Sometimes a slight wiggle or gentle pressure is needed to seat the pin correctly.
- Difficulty with Disassembly Tool: If the tool is not effectively compressing the pin, ensure you are applying pressure directly to the pin's flange. Avoid excessive force to prevent damage to the watch or tool.
- Incorrect Strap Size: Verify that your smartwatch requires a 32MM width strap. This replacement strap is specifically designed for DM100 and LEMFO models with this width. Incompatible sizes will not fit correctly.
