摘要

A resealable module comprises a shell insertable within a receiver-retaining portion of the test set body, and has an acoustic opening adjacent to an acoustic energy coupling portion , when the module is inserted into the receiver-retaining portion of the test set body. A printed circuit motherboard has a plurality of printed circuit modules and is supported on the shell. The introduction of contaminant material into a craftsperson's telephone test set is prevented by modifying the housing configuration of the hand and face-conformal segment by a resealable module accommodates printed circuit compoments.
