§  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.
