Sec. 90.656  Responsibilities of base station licensees of Specialized 
          Mobile Radio systems.

    (a) The licensees of base stations that provide Specialized Mobile 
Radio service on a commercial basis of the use of individuals, Federal 
government agencies, or persons eligible for licensing under either 
subparts B or C of this part will be responsible for exercising 
effective operational control over all mobile and control stations that 
communicate with the base station. The base station licensee will be 
responsible for assuring that its system is operated in compliance with 
all applicable rules and regulations.
    (b) Customers that operate mobile units on a particular Specialized 
Mobile Radio system will be licensed to that system. A customer that 
operates temporarily on more than one system will be deemed, when 
communicating with the other system, to be temporarily licensed to the 
other system and for that temporary period, the licensee of the other 
system will assume the same licensee responsibility for the customer's 
mobile station(s) as if the customer's stations were licensed to that 
other system.
