FCC Statement:
Federal Communication Commission Interference Statement
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.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate this equipment.
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
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following " Contains
TX FCC ID: MDZ-WB116C
The OEM integrator is still responsible for the FCC compliance requirement of the end
product, which integrates this module.
Appropriate measurements (e.g. 15 B compliance) and if applicable additional equipment
authorizations (e.g. Verification , Doc) of the host device to be addressed by the
integrator/manufacturer.

Proximity Pairing
Proximity pairing is headset-initiated pairing and it simplifies the out-of-box pairing process. Proximity pairing
enables
the headset to find the closest discoverable phone. The headset then initiates the pairing activity and the user
simply
has to accept the incoming pairing invitation on the phone.
This means that the phone-user does not have to hunt through phone menus to pair with the new headset.
Depending on the phone UI:
■ For a Bluetooth v2.0 phone the headset pairing is with a PIN code
■ For a Bluetooth v2.1 (or above) phone the headset pairing is without a PIN code
Proximity pairing is based on finding and pairing with the closest phone. To do this, the headset finds the loudest
phone by carrying out RSSI power threshold measurements. The loudest phone is the one with the largest RSSI
power threshold measurement, and it is defined as the closest device. The headset then attempts to pair with
and
connect to this device.
Proximity pairing is configurable using the Headset Configurator tool available from www.csrsupport.com.
