Fitting Instructions:
1. With clean hands, ROLL entire earplug into narrowest possible crease-free cylinder.
2. Reach over head with free hand, pull ear up and out and INSERT earplug well inside ear canal.
3. HOLD for 40 seconds, until earplug fully expands in ear canal.
4. In a noisy environment, with earplugs inserted, cup hands over ears and release. Earplugs should be blocking enough noise so that covering them with handsdoes not result in a significant difference. If proper fit is not obtained, move to a quiet location and repeat fitting instructions.
WARNING! Remove earplugs slowly with a twisting motion to gradually break the seal. Rapid removal may damage the eardrum.
