Sec. 2.1043  Changes in certificated equipment.

    (a) Changes to the basic frequency determining and stabilizing 
circuitry (including clock or data rates), frequency multiplication 
stages, basic modulator circuit or maximum power or field strength 
ratings shall not be performed without application for and authorization 
of a new grant of certification. Variations in electrical or mechanical 
construction, other than these indicated items, are permitted provided 
the variations either do not affect the characteristics required to be 
reported to the Commission or the variations are made in compliance with 
the other provisions of this section.
    (b) Two classes of permissive changes may be made in certificated 
equipment without requiring a new application for and grant of 
certification. Neither class of change shall result in a change in 
identification.
    (1) A Class I permissive change includes those modifications in the 
equipment which do not degrade the

characteristics reported by the manufacturer and accepted by the 
Commission when certification is granted. No filing with the Commission 
is required for a Class I permissive change.
    (2) A Class II permissive change includes those modifications which 
degrade the performance characteristics as reported to the Commission at 
the time of the initial certification. Such degraded performance must 
still meet the minimum requirements of the applicable rules. When a 
Class II permissive change is made by the grantee, he shall supply the 
Commission with complete information and the results of tests of the 
characteristics affected by such change. The modified equipment shall 
not be marketed under the existing grant of certification prior to 
acknowledgement by the Commission that the change is acceptable.
    (3) Permissive changes, as detailed above, shall be made only by the 
holder of the grant of certification. Changes by any party other than 
the grantee require a new application for and grant of certification.
    (c) A grantee desiring to make a change other than a permissive 
change shall file an application on FCC Form 731 accompanied by the 
required fees. The grantee shall attach a description of the change(s) 
to be made and a statement indicating whether the change(s) will be made 
in all units (including previous production) or will be made only in 
those units produced after the change is authorized.
    (d) A modification which results in a change in the identification 
with or without change in circuitry requires a new application for, and 
grant of certification. If the changes affect the characteristics 
required to be reported, a complete application shall be filed. If the 
characteristics required to be reported are not changed the abbreviated 
procedure of Sec. 2.933 may be used.
