2 PROVISIONS APPLICABLE
2.1 Definition
Unintentional radiator:
A device that intentionally generates and radio frequency energy for use within the device, or
that sends radio frequency signals by conduction to associated equipment via connecting
wiring, but which is not intended to emit RF energy by radiation or induction.
Class A Digital Device:
A digital device which is marketed for use in commercial or business environment; exclusive
of a device which is market for use by the general public, or which is intended to be used in
the home.
Class B Digital Device :
A digital device which is marketed for use in a residential environment notwithstanding use
in a commercial, business of industrial environment. Example of such devices that are
marketed for the general public.
Note : A manufacturer may also qualify a device intended to be marketed in a commercial,
business, or industrial environment as a Class B digital device, and in fact is
encouraged to do so, provided the device complies with the technical specifications
for a Class B Digital Device. In the event that a particular type of device has been

This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction may cause harmful interference to radio
communication. However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or television reception, which can
