A internal surface mounted (SMD) antenna. A 1/4 stub antenna for panel montage. An antenna attach to a coaxial cable. See chapter about Mounting for more info about antenna placement. 4.1 1/4 stub antenna Frequency range Polarization Azimuth beam width 2400-2484 MHz Linear Omni directional Picture 1 - Stub antenna 4.2 Coaxial cable antenna Frequency range Polarization Azimuth beam width 2400-2484 MHz Linear Omni directional Picture 2 - Cable antenna 11 4.3 Surface mounted antenna This is a Surface mounted antenna with the dimensions of 15.0x10.0x6.3mm. The unit cannot be mounted in a metal-shielded enclosure with this antenna. Frequency range 2400-2484 MHz Polarization Azimuth beam width Linear Omni directional Picture 3 - SMD antenna 12 Chapter 5 Mounting Instructions 5.1 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 1/4 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. n/2 = 0, 6, 12 cm Figure 1 - Antenna placement A cubic space with 1side around the SMD antenna must be free from wires, circuits or other conductive components of the user application.

R&TTE Directive 1999/5/EC and EMC Directive: 89/336/EEC ETS 300 826 and EN 300 328-2 Low Voltage Directive: 73/23/EEC EN 61131-2 7.2 FCC FCC Statement 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. 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 Connect the equipment into an outlet on a circuit different from that to which the Increase the separation between the equipment and receiver receiver is connected Consult the dealer or an experienced radio/TV technician for help 17 This device contains FCC ID:PVH000501 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 users authority to operate the equipment. 18
