Operating the BOA Fit System
The BOA Fit System provides a precise and customizable fit. Understanding its operation is key to maximizing the brace's effectiveness.
Video: This video demonstrates the application and adjustment of the DonJoy Performance Bionic BOA Fit System Back Brace, showing how to engage the dial, tighten the brace, and use the quick release feature.
- To Tighten: Push the BOA dial in until it clicks, then turn it clockwise. Each click represents a micro-adjustment, allowing you to achieve the exact level of compression required.
- To Loosen/Release: Pull the BOA dial straight outward. This disengages the lacing system, allowing for immediate loosening or removal of the brace.
- Fine-Tuning: Throughout the day, you can easily re-engage and turn the dial to adjust the fit as needed, without removing the brace.
Maintenance
Proper care will extend the life of your DonJoy Performance Bionic BOA Fit System Back Brace and ensure its continued effectiveness.
- Cleaning: Hand wash the brace in cold water with mild soap. Do not use bleach, fabric softeners, or harsh detergents, as these can damage the materials.
- Drying: Air dry completely. Do not machine dry, iron, or expose to direct heat, as this can deform the brace. Ensure the brace is fully dry before storage or re-use.
- Storage: Store in a cool, dry place away from direct sunlight and extreme temperatures.
- BOA System Care: Keep the BOA dial and laces free from dirt, sand, and debris. If needed, gently clean with a damp cloth. Avoid applying oils or lubricants to the BOA mechanism.
Troubleshooting
If you encounter issues with your back brace, consider the following common solutions:
- Discomfort or Pinching: Re-adjust the brace. Ensure it is centered and not too tight in any one area. The BOA system allows for fine adjustments to relieve pressure points. If discomfort persists, loosen the brace or discontinue use.
- Insufficient Support: Ensure the brace is tightened adequately using the BOA dial. Verify that the rigid stabilizers are correctly inserted into their pockets if you require maximum support.
- BOA Dial Not Engaging/Releasing: Check for any debris obstructing the dial mechanism. Ensure you are pushing the dial firmly inward to engage and pulling it straight outward to release. If the dial is stuck, gently try to clear any obstructions.
- Brace Slipping: Ensure the brace is properly sized and tightened to your waist. If the issue persists, re-evaluate your size against the product's sizing guide or contact customer support.
