WHAT TO DO
Make sure there are no air gaps around the ear cushion seals.
NOTE: If the ear cushions appear worn, they should be replaced
(see page 21).
Check the volume setting on your radio/belt pack.
Unplug all other headsets and check if the volume level improves
(for wired intercom system only).
Try a different radio/belt pack.
Move closer to the radio base station.
NOTE: A typical wireless belt pack range is 30-50 yards.
Make sure you're wearing the headset in the correct orientation.
Use the L (left) and R (right) markings inside the earcups
for reference.
Check that the seal between the ear cushion skirt and the earcup fit
properly and there aren't any gaps. Replace any ear cushions that
appear to be worn out.
Adjust the headset fit so that your ears are completely inside the ear
cushions. Make sure that a hat or eyeglasses do not interfere with
the seal.
Make sure the headset ear cushions, internal ear cup foams and
scrims are dry. If not, air dry all parts and retry the headset. If the
problem persists, contact Bose customer service.
