§  95.221   (R/C Rule 21) How do I have my R/C transmitter serviced?

   (a) You may adjust an antenna to your R/C 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.
   Each internal repair and each internal adjustment to an FCC
   certificated R/C transmitter (see R/C Rule 9) must be made in accord
   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 an R/C 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 a transmitter to an antenna;

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

   (3) Tune a receiver to your R/C transmitter.
