2. Setup and Operating Instructions
Insertion:
- Roll the earplug between your fingers to form a tight, smooth, and tapered shape.
- Gently pull back on the top of your ear to straighten the ear canal.
- Insert the tapered end of the earplug into the ear canal.
- Hold the earplug in place until it fully expands and creates a secure seal.
Removal:
- Gently pull the earplug straight out of the ear canal with a slow, twisting motion. Avoid sudden removal.
3. Maintenance
For reusable earplugs, clean them after each use with mild soap and warm water. Rinse thoroughly and allow them to air dry completely before storing or reusing. Ensure earplugs are fully dry to prevent moisture buildup.
4. Troubleshooting
If you experience discomfort or inadequate noise reduction, re-insert the earplugs following the instructions carefully. Ensure the earplug is fully expanded and creates a proper seal within the ear canal. If issues persist, the earplugs may be improperly sized for your ear canal or may need replacement.
