Instructions for continued airworthiness

Bose recommends following the general care and maintenance instructions in
this guide. With normal use, items such as windscreens and ear cushions may
require periodic replacement. If cleaning or replacement of these items is
needed, follow the recommendations on the following pages. All other care and
maintenance, in and out of the warranty period, must be performed by Bose or
an authorized repair facility.
CAUTION: Do not immerse the headset in water or any other liquid. If the
headset is immersed in liquid, do not use it. Contact Bose
assistance.

Cleaning the headset

General cleaning

Gently wipe the outside surfaces of the headband, connectors, plastic parts,
and headband cushion, using a soft cloth moistened with water and mild soap.
Take special care when cleaning the ear cushions and the outside surfaces of
the earcups. Do not immerse ear cushions in water or any other liquid.

Headset earcup openings

®
The TriPort headset opening and the microphone opening must remain clean
and free of debris. Check to ensure that the openings on each earcup are clean
before each flight.
When wiping down the headset 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. Do not blow air into or vacuum
the openings as this may damage the headset.
