A unitary mounting carrier structure supports a display panel and acoustic transducer components within a housing sub-portion of a telephone test set containing a keypad, an earpiece receiver port, a display panel face, and an auxiliary speaker port at an end portion of the test set. The unitary carrier structure is generally wedge-configured and has a generally flat, liquid crystal display panel unit-mounting section upon which a shock-absorbing gasket assembly containing a display panel unit is mounted. An earpiece receiver-mounting section is contiguous with a wider end of the carrier, and is contiguous with the generally flat, display panel unit-mounting section. An auxiliary speaker-mounting section is supported by the carrier adjacent and transverse to the earpiece receiver-mounting section. A desiccant-retaining section is supported adjacent to the display panel unit-mounting section, and serves to reduce the dew point within the test set to a value in a range on the order of 0 DEG -65 DEG F., thereby preventing the display panel unit from 'fogging-up', as may otherwise occur when the test set is taken from an air-conditioned vehicle to a warm and humid outdoor environment.
