6. Troubleshooting

If you encounter any issues with your JZBRAIN Compression Boots, please refer to the following common problems and solutions.

Device Does Not Power On:

• Ensure the battery is charged. Connect the control unit to a 5V/2A USB power source and allow it to charge for at least 30 minutes before attempting to power on again.
• Press and hold the On/Off button for a few seconds to ensure it registers.

Boots Are Not Inflating or Losing Pressure:

• Ensure the zippers on the boots are fully closed and there are no tears or punctures in the fabric.
• Verify that the selected intensity level is appropriate. Start with a lower intensity and gradually increase.

Battery Life is Shorter Than Expected:

• Ensure the device is fully charged before each use (approximately 235 minutes).
• Operating at higher intensity levels may consume battery faster.
• Battery performance can degrade over time with repeated charging cycles.

Unusual Noises During Operation:

• A low humming sound is normal during inflation/deflation.
