Appendix II - Tape recorder/Hi-Fi output
The speech signal is present as a high impedance output on the line lead as well as a UHF output. To record some speech, plug the line lead into the "MIC" input in your tape recorder, set it to "RECORD" and any speech produced by the unit will be recorded on tape. To output speech to an external amplifier, connect the line lead to the "AUX" or "TAPE" input on your amplifier, via a suitable connecting lead.
