Abstract
A hand-held radio has thumbwheels for channel selection extending outwardly of an aperture in the top panel of the case, and a cover of resiliently deflectable transparent synthetic resin is disposed thereover and effects a seal thereabout to substantially prevent rain and spray from entering the interior through the apertures about the thumbwheels. The cover has a pedestal portion with a top wall spaced above the thumbwheels and with an inclined sidewall which is spaced laterally outwardly from the thumbwheels, and a peripheral flange extends about the base of the sidewall. A clamping plate has an aperture through which the pedestal portion extends, and it overlies the flange of the cover. Fasteners seated in the clamping plate tightly clamp the flange of the cover against the top panel of the case to effect a seal. The user is able to deflect the cover top wall downwardly and then laterally to rotate the thumbwheels.
