Adjusting the volume
The volume for your headset is controlled by the grooved knobs
located on the front side of the headband arms.
Avoid setting your volume controls at high levels that may affect your
hearing during extended periods of headset use.
Note: The volume controls and the active noise reducing circuitry
work only when the headset is turned on (Figure 6).
Note: The volume cannot be turned off completely.

Fail-resistant operation

The headset provides communication and the earcups block some
noise even with the power switch on your headset turned off, bypass-
ing all active noise reducing electronics. Turn the headset off if you
suspect there may be a problem; for more information, refer to "In Case
of Difficulty" (page 20).
