The manual was written by myself, Richard John Torrens, with illustrations by Stan North, about 1973. I was the service manager and was responsible for all repairs, technical enquiries, returns under guarantee, refund requests etc. So the 30 page A4 size manual is extremely comprehensive and leaves nothing to chance! It is also extremely honest about the performance available.
