IMPORTANT SAFETY INSTRUCTIONS

WARNING
Read all safety warnings, instructions, illustrations and specifications provided. Save all warnings and instructions for future reference.

• Failure to follow these instructions can result in hearing loss or injury.

• Only use accessories specifically recommended for this tool. Others may be hazardous.

• Misuse, improper fit, or failure to wear hearing protectors during all exposure may result in hearing loss or injury.

• Rapid removal may damage the eardrum. For greater control and safety, remove ear tip slowly with twisting motion to gradually break the seal.

• Inspect before use and discard if ear tip silicone/foam tips are cracked, torn, dirty, hard, or deformed.
  Earbuds should be clean and soft before use. Damaged earbuds could break in ear canal.

• Wash hands before use. Use clean earbuds.

Fitting Ear Tips

1. To remove ear tips, gently pull the tip away from the earbud. To install ear tips, push tip onto earbud until snug.

2. Inspect ear tips before use.
   For silicone banded tip:
   • Position ear tip in the desired wearing position.
   • While pulling ear outward and upward with opposite hand, insert ear tip into ear canal.
   Adjust for best noise reduction.
   For foam tip:
   • Gently roll the foam tip between thumb and fingers slowly increasing pressure until earbud is compressed into a thin, smooth cylinder.
   • Pull the outer ear up and back with one hand, and insert the ear tip into the ear canal with the other hand.
   • Hold the earbud in place for at least 40 seconds, allowing the ear plug to expand down into the ear canal.

3. Check fit: When this device is well-fitted, your voice should sound louder, deeper and hollow when you talk.
   WARNING! Rapid removal may damage the eardrum. For greater control and safety, remove ear tip slowly with twisting motion to gradually break the seal.

4. Remove earbuds slowly with a twisting motion to gradually break the seal.

5. Wash ear tips with only mild soap and warm water as needed. Look for tears or cracks under any of the silicone banded tip flanges/foam tips.

6. Replace if ear tips are damaged or no longer hold ear tips firmly in place when worn, if ear tips are damaged or if ear tips are not soft and pliable.
   WARNING! Rapid removal may damage the eardrum. For greater control and safety, remove ear tip slowly with twisting motion to gradually break the seal.
   If you cannot obtain a good fit, try a different size or style ear tip.

Noise Reduction Rating

WARNING
Rapid removal may damage the eardrum. For greater control and safety, remove ear tip slowly with twisting motion to gradually break the seal.
The level of noise entering a person’s ear, when a hearing protector is worn as directed, is closely ap­proximated by the difference between the A-weighted environmental noise level and the NRR.

Example:

1. The environmental noise level as measured at the ear is 92 dBA.
2. The NRR is 22 decibels (dB).
3. The level of noise entering the ear is approximately equal to 70 dBA.

CAUTION
For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used. Improper fit or inconsistent use of this device will re­duce its effectiveness attenuating noise. Consult the enclosed instructions for proper fit.
Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the noise reduction rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire.
For example, gunfire exposure depends on the weapon type, number of rounds fired, proper selec­tion, fit and use of earplugs, proper care of hearing protection, etc.
The US EPA specifies the NRR as the measure of hearing protector noise reduction. However, MILWAUKEE makes no warranties as to the suitabil­ity of the NRR for this purpose. Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in earplug fit, earplug fitting skill and motivation of the user. It is recommended that the NRR be reduced by 50% to better estimate typical workplace protection.
