To maintain the noise attenuation properties of the Headset, the Ear Cushions (see
Figure 8.0, item 4) should be replaced every six months and the inner foam and
spacer assembly (see Figure 8.0 , item 3) every twelve months. More frequent
replacement of these items may be required if the Headset is being used under
extreme conditions. Inspect the headset regularly for signs of damage or wear.
