7.4. DUAL PROTECTION AND EARPLUG
MODE
The Tactical Modular Audio System (TMAS) is designed to
allow dual hearing protection for high noise exposures. The
TEP-300 or a non-electronic (passive) hearing protector can
be worn under the ComTac™ VII to achieve dual hearing
protection. When a non-electronic (passive) hearing
protection device is used, it may be necessary to place the
ComTac™ VII in Earplug Mode to maintain environmental
auditory awareness and communications.
NOTE: The user must achieve an adequate hearing protector
