Sec.  80.969   Illumination of operating controls.

   (a) The radiotelephone must have dial lights which illuminate the operating
   controls at the principal operating position.

   (b) Instead of dial lights, a light from an electric lamp may be provided to
   illuminate the operating controls of the radiotelephone at the principal
   operating position. If a reserve power supply is required, arrangements must
   permit the use of that power supply for illumination within one minute.
