*The two band sections that the radio could receive were divided into five sub-bands, designated by the Roman numerals at the left.  The band selector switch is at the lower left and is color coded.

*At the lower right is the on/off switch:  "Aus" is for "off," and "Ein" is for "on."

*The knob to the right of the band selector switch reads, "Lautstärke."  It means "loud" (volume).
