this chapter (cellular telephone bands). Receivers capable of ``readily 
being altered by the user'' include but are not limited to, those for 
which the ability to receive transmissions in the cellular telephone 
bands can be added by clipping the leads of, or installing, a simple 
component such as a diode, resistor and/or jumper wire; replacing a 
plug-in semiconductor chip; or programming a semiconductor chip using 
special access codes or an external device, such as a personal computer. 
Scanning receivers, and frequency converters designed or marketed for 
use with scanning receivers, must also be incapable of converting 
digital cellular transmissions to analog voice audio.
    (b) Scanning receivers, and frequency converters designed or 
marketed for use with scanning receivers, that are manufactured 
exclusively for, and marketed exclusively to, entities described in 18 
U.S.C. 2512(2) are not subject to the requirements of paragraph (a) of 
this section.
