Abstract: A multi-position rotary control provides authentication for a battery operated portable communication device. The rotary control provides a rotary switch pin code which is combined with voice authentication as part of an authentication process. Upon completion of authentication, the rotary control reverts back to a default radio control.

Abstract: A grille configured for shielding a microphone cavity. The grille includes a first side. The first side includes a first plurality of parallel slats defining a first plurality of channels extending along a first direction. The grille includes a second side opposite the first side. The second side includes a second plurality of parallel slats defining a second plurality of channels extending along a second direction at a first angle relative to the first direction. The first plurality of parallel slats and the second plurality of parallel slats define a lattice having a plurality of openings extending through the grille. The openings are configured to diffuse air moving across the lattice. The channels and slats are configured to induce capillary action on water coming in contact with the lattice to drain water from the openings and the microphone cavity.
