Sec. 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 type 
accepted 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.
