As used in this chapter, unless the context otherwise requires:
In determining whether a device that is alleged to be an electronic, mechanical, or other device is, in fact, such a device, there must be taken into account, among other things, the size, appearance, directivity, range, sensitivity, frequency, power, or intensity, and the representation of the maker or manufacturer as to its performance and use.
