The Microtext adaptor does not include a UHF/VHF decoder. Instead, it requires a composite video signal - which can be obtained from following sources:
* From the '''Video Out''' socket of a Video Recorder (if one does own a VCR)
* From the '''Microtext's Tuner''' (which was sold separately, for users whom who don't own VCRs)
** The Microtext Tuner was intended to supply a Composite signal for Teletext adaptor.
** Ie. unlike other [[CPC]] Tuners (like the [[MP-3]]) which were intended to supply a RGB signal to the [[CTM640/CTM644|CTM644]] monitor.
