FCC Warning Statements
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 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.
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.
FCC Caution: Any changes or modifications not expressly approved by BiancaMed could void
the user's authority to operate this equipment.
This transmitter module is authorized to be used in other devices only by OEM further
transmitter testing will not be required. However, the OEM integrator is still responsible for
testing their end-product for any additional compliance requirements required with this
module installed (for example, digital device emissions, PC peripheral requirements, etc.).
The OEM integrator has to be aware not to provide information to the end user regarding how
to install or remove this RF module in the user manual of the end product.
End Product Labeling
The final end product must be labeled in a visible area with the following:
“Contains TX FCC ID: YAKBM08” or “Contains FCC ID: YAKBM08”.
