Sec. 22.575  Use of mobile channel for remote control of station 
          functions.

    Carriers may remotely control station functions (e.g. shut down or 
reactivate base transmitters, turn aviation obstruction warning lights 
on or off, etc.) using a control transmitter operating on a mobile 
channel, subject to the conditions in this section and in 
Sec. 22.567(h).
    (a) The control transmitter must be capable of overriding 
transmissions from subscriber-operated transmitters if necessary. 
Subscriber-operated transmitters must not be capable of being used to 
deliberately or accidentally prevent the licensee from controlling the 
station.
    (b) The licensee must implement measures designed to prevent station 
functions from being controlled by persons not authorized by the 
licensee to control the station.
    (c) The control transmitter location must be within the composite 
service contour of the licensee's authorized station on the paired base 
channel.
