3. Safety Information

Proper use of hearing protection is crucial for preventing noise-induced hearing loss. Always follow these safety guidelines:

• Fit: Ensure a snug fit around the ears to achieve the stated Noise Reduction Rating (NRR). Any gaps will reduce effectiveness.
• Inspection: Before each use, inspect earmuffs for damage, cracks, or wear on earcups, cushions, and headband. Replace if damaged.
• Cleaning: Keep earmuffs clean to maintain hygiene and performance. Refer to the Maintenance section.
• Limitations: Earmuffs reduce noise but do not eliminate it entirely. In extremely loud environments, additional hearing protection may be necessary.
• Proposition 65 Warning: This product may expose you to chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.

4. Setup and Adjustment

To ensure maximum protection and comfort, follow these steps for proper setup and adjustment:

1. Extend Headband: Pull the earcups outward from the headband to extend the arms.
2. Position Earmuffs: Place the earmuffs over your ears, ensuring the headband rests comfortably over the top of your head.
3. Adjust Height: Slide the earcups up or down along the headband arms until they fully enclose your ears and the cushions create a firm, comfortable seal around your ears.
4. Check Fit: The headband should apply even pressure, and the earcups should not press against your ears uncomfortably. Adjust as needed.

5. Operating Instructions

Once properly fitted, the 3M Optime 98 Earmuffs are ready for use. Wear them continuously in noisy environments to protect your hearing. Remove them only when you are no longer exposed to hazardous noise.

6. Maintenance

Regular maintenance helps prolong the life and effectiveness of your earmuffs:

• Cleaning: Clean the earcups and headband regularly with mild soap and water. Do not immerse the earmuffs in water. Wipe dry with a clean cloth.
• Cushion Replacement: Earcup cushions and foam inserts may degrade over time. Replace them periodically, or if they show signs of wear, hardening, or damage, to maintain optimal noise reduction and hygiene.
• Storage: Store earmuffs in a clean, dry place away from direct sunlight, extreme temperatures, and chemicals when not in use.

7. Troubleshooting

If you experience reduced noise protection or discomfort, consider the following:

• Poor Seal: Re-adjust the earmuffs to ensure a complete seal around your ears. Hair, eyeglasses, or other obstructions can break the seal.
• Damaged Components: Inspect earcups, cushions, and headband for any visible damage. Replace worn or damaged parts.
• Discomfort: Ensure the headband is not too tight or too loose. Adjust the earcup height for a comfortable fit.
