CLEAN THE HEADSET
Your headset may require periodic cleaning.
COMPONENT CLEANING PROCEDURE
Headset
Wipe the outside surfaces of the headband, headband cushion, earcup  
cushions, connectors, and plastic parts using a soft, damp cloth (water 
only) and mild soap. 
CAUTION: Do NOT immerse the headset in water or any liquid.
Earcup  
openings
 
Check to make sure that the 
openings on the outside of each 
earcup are clean and free of 
debris before each flight.
When wiping down the  earcups, 
be sure not to force any dirt 
or  debris into the openings. 
 Carefully use  tweezers, if 
 necessary,  to   remove   foreign 
matter that may be lodged in  
the   openings. 
CAUTION: Do NOT blow air into or vacuum the  openings, as this may 
damage the headset.

Do not attempt to remove, replace, repair, or clean the inner screen inside 
the earcup. If the screen appears to be damaged or worn out, contact Bose 
customer service.
If the inner screen becomes damp from environmental moisture such as 
light rain, dew, perspiration, or condensation, allow it to air dry only.
CAUTION: Do NOT use electric heaters, blowers, or hair dryers to dry the 
inner screen.
