13 Chapter 5 Mounting 5.1 Instructions The module cannot be mounted arbitrary, because off the radio communication. The antenna of the module cannot be mounted in a metal enclosure. If a metal enclosure is required, the Stub antenna (see 1/4λ stub antenna) could be mounted through a panel hole or the coaxial antenna could be mounted outside the enclosure via the coaxial cable (see Coaxial cable antenna). The antenna should NOT to be mounted with a distance of multiple half wavelengths (6cm) from a conductive surface. Figure 1 - Antenna placement The minimum distance between the user application printed circuit board and the OEM-Bluetooth module is 3mm (0.118”) ≠n⋅λ/2 = 0, 6, 12 cm A cubic space with 1”side around the SMD antenna must be free from wires, circuits or other conductive components of the user application.

Operation is subject to the following two 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. 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
18 Labeling Requirements for End Product For an end product using the OEM Serial Port Adapter or the OEM Bluetooth Enabler there must be a label containing, at least, the following information: The label must be affixed on an exterior surface of the end product such that it will be visible upon inspection in compliance with the modular approval guidelines developed by the FCC. In addition, the user manual for the end product must contain the following information: “This device complies with Part 15 of the FCC Rules. Operation is subject to the following two 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.” RF-exposure statement This mobile modular transmitter must have a separation distance of at least 20cm between the antenna and the body of the user or nearby persons. With a separation distance of 20cm or more, the MPE limits are well above the potential this module is capable to produce. Antenna When using the module equipped with the “Coaxial cable antenna” or the “Stub antenna” the antenna is fixed and cannot be removed or replaced by the end user. Caution Any changes or modifications NOT explicitly APPROVED by connectBlue AB could cause the module to cease to comply with FCC rules part 15, and thus void the user’s authority to operate the equipment. This device contains FCC ID:PVH000501
