To determine if an advertisement is misleading, the following, in addition to any other appropriate considerations, shall be considered:

(1) Any representation made by statement, word, design, device, or sound, whether alone or together; and

(2) The extent to which the advertisement fails to reveal a fact which, in light of any representation made, is material with respect to the advertised commodity or service under conditions which are:

(i) Customary or usual; or

(ii) Described in the advertisement.
