The "proper position" is just a reference to there being a dedicated position on the wave change switch for "gram" which substitutes the gram input signal for the detector output. Some sets skimped on this as described by just taking the gram input straight to the volume control leaving the user to simply find a signal free spot on one of the wavebands to avoid unwanted noise on the gram signal.
