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.
