Contains Module FCC ID: HV4RY24TL, IC: 6888A-RY24TL Any similar wording that expresses the same meaning may be used. (5) Caution to user for modification The following caution is expressed on the user’s instruction manual. The changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the device. (6) Compliance statement to FCC The following statement is expressed on the user’s instruction manual. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. 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 be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. (7) Compliance statement to IC The following statement is expressed on the user’s instruction manual. Operation is subject to the following conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

7 4. Control specification 4.1 Requirements for power on procedure CPU I/F will available to access with command 150ms after power supply had stabled. BS/PS pin have to be fixed before not passed 120ms after power supply had stabled. When BS mode is selected, this module starts a sequence for searching the other BS module. After the searching sequence, a table of used is decided. (Max 6 tables) 4.2 Reset For reset module, input low pulse to RESET pin Low. After reset, It is necessary to keep time condition same as after power on. 4.3 Operation mode selection Operation mode is decided as follow. <BS/PS pin> Low/Open : PS Mode High : BS Mode 4.4 User ID write/read User can rewrite ID by using ID_0, ID_1 and serial pin. <ID1 / ID0> 0 0 : Normal 0 1 : Not specified 1 0 : ID write 1 1 : ID read
