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.

The minimum distance between the user application printed circuit board and the
OEM-Bluetooth module is 3mm (0.118”)

The main board is 65.0x40.0x1.6mm excluding the mounting wings. The wings are
electrical isolated and can for example be mounted in the mounting rails of a metal
enclosure. The wings can be removed by V-Cuts.

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
• 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

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.
