WARNING! Performance may deteriorate with battery usage.
The typical period of continuous use that can be expected from this product is 1000 hours. Continous use is defined as 20% use in silent
noise 45-50dB(A), 60% use in medium noise 70-75dB(A) and 20% use in high noise 95-100dB(A). The expected battery life time can vary
with battery brand and the temperature in which the product is being used.
• Polarity protection prevents damage to circuits if the batteries are inserted incorrectly.
• Equipped with an audio input via a chassis jack for connecting an external radio.
• When the level dependent function is on, the amplification is toned down when an external signal comes in through the audio input.
• When external volume is set at normal a summary stage ensures that the combined sound level of all incoming audio signals inside the cup
never exceeds 82 dB.

IMPORTANT USER INFORMATION
The hearing protector must be put on, adjusted, cleaned and maintained in accordance with the instructions in this manual.
• This ear-muff 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 manufacturers advice for maintenance and replacement of the battery
• Wear the headset 100% of the time you spend in noisy environments for full protection.
• This product may be adversely affected by certain chemical substances. Contact 3M for additional information.
• This ear-muff 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 manufacturers advice.
• When interference increases or the volume becomes too weak, it is time to replace the batteries. Never replace or install batteries with the
unit switched on. Ensure that the battery is positioned correctly before using. See the figure in the CARE section.
• Do not store with the batteries installed.
• In extremely cold conditions, warm up the hearing protector before use.
• Ear-muffs, and in particular cushions, may deteriorate with use and should be examined at frequent intervals for cracking and leakage, for
example.
• The fitting of hygiene covers to the cushions may affect the acoustic performance of the ear-muffs.
Note: If these recommendations are not followed, attenuation and other functions can be impaired.
• Intrinsically safe approval does not apply if technical changes are made in Ex-approved products. Only accessories with the same type
designation as original equipment may be used.
WARNING!
The output of the level-dependent circuit of this hearing protection may exceed the external sound level.
Warning! The output of the electrical audio circuit of this hearing protector may exceed the daily limit sound level.
IMPORTANT! For the best protection, brush aside hair around the ears so the ear cushions fit snugly against the head. Spectacle frames should
be as thin as possible and fit close to the head.
IMPORTANT!
For safe use of intrinsically safe Tactical XP versions, for use in potentially explosive environments, please read Ex safety guide (A)
