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.
