Ear cushion replacement

As a general rule, ear cushions should be replaced every six months or every

350 hours of use, depending on how often you fly. You may have to replace

them more often, if you:

• Have a full beard or heavy whiskers.

• Subject the headsets to severe temperature extremes such as parking your

airplane outside in severe cold or heat.

• Put excess strain on the cushions because of improper storage.

Indications that the ear cushions need replacing include:

• Flaking of the outer covering.

• Cuts or tears.

• Flattening of the cushion, reducing the effectiveness of the seal.

To extend the life of the ear cushions, perform regular cleaning as described in

"General cleaning" on page 23.

Replacing the ear cushions

1. Grasp the ear cushion skirt where it folds into the slot on the earcup.

2. Gently pull the ear cushion skirt up and away from the earcup.

3. Properly align the replacement ear cushion with the earcup.

4. Tuck an edge of the ear cushion skirt into the slot behind the ear cushion

flange. Be careful not to fold the skirt over.

5. Work the remainder of the skirt into the slot completely around the earcup.

6. Grasp the ear cushion and adjust its position to remove any folds in the

skirt and wrinkles in the cushion.

Refer to "Inserting and replacing the batteries" on page 10.
