CARE & MAINTENANCE
We recommend that your headset be cleaned regularly, by wiping with a damp
sponge containing mild soap and water. Pay special attention to the Ear Cushions
to ensure removal of perspiration and skin oils which can reduce the service life of
the Cushions. These areas of the Headset that come into contact with the wearer’s
skin should also be regularly disinfected using isopropyl alcohol wipes.
When cleaning DO NOT allow moisture to enter the Ear Cup assemblies or any part
of the Microphone Assembly. UNDER NO CIRCUMSTANCES SHOULD YOU
IMMERSE THE HEADSET IN ANY LIQUID.
To maintain the noise attenuation properties of the Headset, the Ear Cushions (see
Figure 6.0, item 5) should be replaced every six months and the inner foam
assembly (see Figure 6.0, item 4) 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.

IMPORTANT: This Headset should not be stored in direct
sunlight or temperatures above 55 degrees C. as distortion
of the Ear Cushions may occur.
PARTS REPLACEMENT (See items 1 – 5 pictured in Figure 6.0)

- Step 1” and simply reverse the process by unscrewing, counter clockwise, the
knurled nut at the base of the Microphone boom.
The EAR CUSHIONS (item 5) are removed by placing one or two fingers inside the
Ear Cup and under the Ear Cushion’s rigid plastic plate. Hold the Ear Cup firmly
with the other hand and pull the Ear Cushion plate until it pops out of the Cup. The
new Cushions just clip back into place under the lip around the circumference of the
ear Cup opening. Ensure the Ear Cushion plate has seated and clipped-in properly
before use.
The INNER FOAM ASSEMBLY (item 4) also supports the Earphone and care
should be taken not to damage the wiring. With the Ear Cushions removed,
carefully take out the foam wafer and pull apart the two bottom layers where the
