Sec. 74.635  Unattended operation.

    (a) TV relay stations, TV translator relay stations, TV STL 
stations, and TV microwave booster stations may be operated unattended 
under the following conditions:
    (1) The transmitter must be provided with adequate safeguards to 
prevent improper operation.
    (2) The transmitter shall be so installed and protected that it is 
not accessible to other than duly authorized persons;
    (3) TV relay stations, TV STL stations, TV translator relay 
stations, and TV microwave booster stations used with these stations, 
shall be observed at the receiving end of the microwave circuit as often 
as necessary to ensure proper station operation by a person designated 
by the licensee, who must institute measures sufficient to ensure prompt 
correction of any condition of improper operation. However, an STL 
station (and any TV microwave booster station) associated with a TV 
broadcast station operated by remote control may be observed by 
monitoring the TV station's transmitted signal at the remote control 
point. Additionally, a TV translator relay station (and any associated 
TV microwave booster station) may be observed by monitoring the 
associated TV translator station's transmitted signal.
    (b) The FCC may notify the licensee to cease or modify operation in 
the case of frequency usage disputes, interference or similar situations 
where such action appears to be in the public interest, convenience and 
necessity.
