Fig D. To convert the headset for left ear use, first pull out the front
part of the boom (on noise-cancelling models) then rotate it
downward so that it faces the opposite direction. Voice tubes
should simply be rotated.
Fig E. Rotate the receiver downward in the opposite direction to the
boom. The headset is now converted for left ear wear.
Fig F. Quick Disconnect™ Connector – This feature allows you to
move away from the telephone wearing your headset without
disconnecting your call. Before using your headset, join the
connectors together. To move away from your desk, pull the
connectors apart. To resume your call, reconnect.
Clothing Clip – The clothing clip helps to keep the headset free
from the weight of the headset cable. Attach the clip to your
clothing at a comfortable level.
