Abstract

Et telefonmodulsett er innrettet for montering på en vanlig mikrotelefon (12) og et vanlig telefonapparat (152). En mikrotelefonmodul (10) som inngår i modulsettet utgjør en fjernenhet i kombinasjon med mikrotelefonen (12) og omfatter et hylster med elektrisk kretsutstyr (fig. 3). Dette kretsutstyr omfatter en senderdel (78) og en motagerdel (80) for audiosignaler. Et koblingsorgan (70) forbinder kretsutstyrets senderdel (78) elektrisk med en mikrofon i mikrotelefonen (12). Dette elektriske forbindelseorgan (70) forbinder også kretsutstyrets mottagerdel med en høretelefon i mikrotelefonen (12). Mikrotelefonmodulen (10) omfatter også midler for å feste hyl-steret (14) på mikrotelefonen (12). En apparatmodul (150) dan-ner en basis-enhet for anordningen i kombinasjon med telefon-apparatet (152). Apparatmodulen omfatter sender- og mottager-kretser (182, 184) og koblingsorganet (180) for å utveksle. signaler med apparatet (152) .
