Sec.  95.424   (CB Rule 24) How do I have my CB station transmitter serviced?

   (a) You may adjust an antenna to your CB transmitter and you may make radio
   checks. (A radio check means a one way transmission for a short time in
   order to test the transmitter.)

   (b) You are responsible for the proper operation of the station at all times
   and are expected to provide for observations, servicing and maintenance as
   often as may be necessary to ensure proper operation. You must have all
   internal repairs or internal adjustments to your CB transmitter made in
   accordance with the Technical Regulations (see subpart E). The internal
   repairs or internal adjustments should be performed by or under the
   immediate supervision and responsibility of a person certified as
   technically qualified to perform transmitter maintenance and repair duties
   in the private land mobile services and fixed services by an organization or
   committee representative of users in those services.

   (c) Except as provided in paragraph (d) of this section, each internal
   repair and each internal adjustment of a CB transmitter in which signals are
   transmitted must be made using a nonradiating (“dummy”) antenna.

   (d) Brief test signals (signals not longer than one minute during any five
   minute period) using a radiating antenna may be transmitted in order to:

   (1) Adjust an antenna to a transmitter;

   (2) Detect or measure radiation of energy other than the intended signal; or

   (3) Tune a receiver to your CB transmitter.
