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.
