whose primary function is video reception and delivery.

1.2
In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to
satisfy in order to comply with the standard; “should” is used to express a recommendation or that which
is advised but not required; and “may” is used to express an option or that which is permissible within the
limits of the standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a
note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as
requirements.
Annexes are designated normative (mandatory) or informative (nonmandatory) to define their
application.
