3M PELTOR LiteCom Plus MT7H7 4410-EU Series Manual page 8

CAUTION:
Risk of explosion if battery is replaced by an incorrect type.
NOTE
• When worn according to the User Instructions, this hearing protector helps reduce exposure to both continuous noises,
such as industrial noises and noises from vehicles and aircraft, as well as very loud impulse noises, such as gunfire. It
is difficult to predict the required and/or actual hearing protection obtained during exposure to impulse noises. For gun-
fire, the weapon type, number of rounds fired, proper selection, fit and use of hearing protection, proper care of hearing
protection, and other variables will impact performance. To learn more about hearing protection for impulse noise, visit

• This earmuff is provided with level-dependent attenuation. The wearer should check correct operation before use. If
distortion or failure is detected, the wearer should refer to the manufacturer's advice for maintenance and replacement
of the battery.
• This earmuff is provided with electrical audio input. The wearer should check correct operation before use. If distortion
or failure is detected, the wearer should refer to the manufacturer's advice.
