Abstract
A portable communication device has a modular inner chassis containing a main printed circuit board and an outer housing for releasable engagement over the inner chassis so as to substantially completely enclose and conceal the inner chassis. The outer housing has at least two parts. A first part of the outer housing contains a keypad and a separate keypad printed circuit board for connection with a keypad connector on the main printed circuit board when the housing is engaged over the inner chassis. The outer housing and inner chassis have releasable interengaging formations for releasably securing the first and second parts of the outer housing over the inner chassis.
