Caution : Any changes or modifications to this device not explicitly approved by manufactur er could void your authority to operate this equipment. End Product Labeling The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains Transmitter Module FCC ID: BEJPCRCUDT4 or Contains FCC ID: BEJPCRCUDT4. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. 7.2 IC (Certification) This device complies with RSS-210 of the Industry Canada Rules.
