WARNING
• Improper fit of this device will reduce its effectiveness to
reduce noise levels.
• Follow these instructions for proper fit.
• Ear plugs can be recommended for protection against the
harmful effects of impulsive noise. The Standard Noise
Reduction (SNR) 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. Constant
or repetitive exposure to impulsive noise may lead to serious
injury, temporary or permanent deafness.
• These ear plugs, whilst designed to protect ears from injury,
do not provide unlimited protection.
• These ear plugs are single person use. If another person is
required to use them the pods must be changed.
