be turned off. The following notice must be posted on or near each 
cellular telephone installed in any aircraft:
    ``The use of cellular telephones while this aircraft is airborne is 
prohibited by FCC rules, and the violation of this rule could result in

while this aircraft is on the ground is subject to FAA regulations.''
