Sec.  95.194   (FRS Rule 4) FRS units.

   (a) You may only use an FCC certified FRS unit. (You can identify an FCC
   certified FRS unit by the label placed on it by the manufacturer.)

   (b) You must not make, or have made, any internal modification to an FRS
   unit. Any internal modification cancels the FCC certification and voids your
   authority to operate the unit in the FRS.

   (c) You may not attach any antenna, power amplifier, or other apparatus to
   an FRS unit that has not been FCC certified as part of that FRS unit. There
   are no exceptions to this rule and attaching any such apparatus to a FRS
   unit cancels the FCC certification and voids everyone's authority to operate
   the unit in the FRS.

   (d) FRS units are prohibited from transmitting data in store-and-forward
   packet operation mode.
