Sec. 22.373  Access to transmitters.

    Unless otherwise provided in this part, the design and installation 
of transmitters in the Public Mobile Services must meet the requirements 
of this section.
    (a) Transmitters and control points, other than those used with in-
building radiation systems, must be installed such that they are readily 
accessible only to persons authorized by the licensee to operate or 
service them.
    (b) Transmitters must be designed and installed such that any 
adjustments or controls that could cause the transmitter to deviate from 
its authorized operating parameters are readily accessible only to 
persons authorized by the licensee to make such adjustments.
    (c) Transmitters (other than hand-carried or pack-carried mobile 
transmitters) and control points must be equipped with a means of 
indicating when the control circuitry has been put in a condition that 
should cause the transmitter to radiate.

    (d) Transmitters must be designed such that they can be turned off 
independently of any remote control circuits.
    (e) Transmitters used with in-building radiation systems must be 
installed such that, to the extent possible, they are readily accessible 
only to persons authorized by the licensee to access them.
    (f) Transmitters used with in-building radiation systems must be 
designed such that, in the event an unauthorized person does gain 
access, that person can not cause the transmitter to deviate from its 
authorized operating parameters in such a way as to cause interference 
to other stations.
