Maintenance
- Cleaning: Wipe the surface of the leg boots and control unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.
- Storage: After each use, ensure the boots are fully deflated. Store the system in the provided carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Air Hoses: Periodically check the air hoses for any kinks, cracks, or damage. Replace if necessary.
Troubleshooting
- Device not powering on: Ensure the power adapter is securely connected to both the control unit and a working power outlet.
- Boots not inflating or uneven pressure: Check that all air hose connections are secure and free from kinks. Ensure the boots are zipped up completely. The intelligent sensor system adjusts pressure, so slight variations might be normal.
- Control unit unresponsive: Try powering off the device, unplugging it, waiting a few minutes, and then plugging it back in and powering on again.
- Uncomfortable pressure: Adjust the 'STRENGTH' setting to a lower intensity. Ensure the boots are not too tight when worn.
