AL8CA12CDXXXXWireless Headset Adapter - Base Unit

FCC REQUIREMENTS PART 15 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. 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 instal- lation. 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 deter- mined by turning the radio or television off and on, the user is encouraged to try to correct interference by one or more of the following measures: 1. Reorient or relocate the receiving antenna. 2. Increase the separation between the equipment and receiver. 3. Connect the equipment into an outlet on another circuit. 4. Consult the dealer or an experienced radio/TV technician for help. Exposure to Radio Frequency Radiation This device and its antenna must not be co-located or operated in conjunction with any other antenna or transmitter. To com- ply with FCC RF exposure requirements, only use the supplied antenna. The radiated output power of this internal wireless radio is far below the FCC radio frequency exposure limits. Nevertheless, the wireless radio shall be used as described in the manual. The internal wireless radio operates within guidelines found in radio frequency safety standards and recommendations, which reflect the consensus of the scientific community. Plantronics therefore believes the internal wireless radio is safe for use by consumers. The level of energy emitted is far less than the electromagnetic energy emitted by wireless devices such as mobile phones. However, the use of wireless radios may be restricted in some situations or environments, such as aboard airplanes. If you are unsure of restrictions, you are encouraged to ask for authorization before turning on the wireless radio. NOTE: Modifications not expressly approved by Plantronics, Inc. could void the user’s authority to operate the equipment.

EUT Description The Plantronics Model CA12CD is a cordless push-to-talk (PTT) headset adapter made to provide wireless communications and PTT functionality for dispatch operations. The system consists of a base unit that interfaces to a dispatch console communication system, and a remote unit with PTT that communicates with the base station. The remote unit has an “Ultra” style, quick disconnect connector, which attaches to a Plantronics “H” top headset that is worn by the user. The base unit provides a docking cradle for charging the remote unit and a spare battery, and is provided with an AC power adapter. Both the remote unit and the base unit are intentional radiators, designed in accordance with the requirements of 47CFR15 subpart D. The specific units tested were base unit #31 and headset #32. 2/182 I-B. Manufacturer’s Attestations, Mandatory Declarations and Descriptions The CA12CD Remote Unit and CA12CD Base Station Unit both use digital modulation. Clause 4.11 in V3.3 of (draft) C63.17-2005 requires the following declarations to be made by the manufacturer. These declarations are used in demonstrating compliance with certain sections of 47CFR15 subpart D, and in support of test parameters within V3.3 of (draft) C63.17-2005. The channel plan. Five RF carriers are used, as follows: 1928.448 MHz. 1926.720 MHz. 1924.992 MHz. 1923.264 MHz. 1921.536 MHz. Maximum EUT antenna gain GA (dBi), and orientation and polarization for maximum gain. The maximum remote EUT antenna gain is 0dBi. The antenna is elliptically polarized with the major axis of polarization normal to the top external surface of the remote disposed away from the user’s hand and/or body, and with the minor axis of polarization parallel to the length of the major axis of the remote. Two identical collocated antennas are provided for the base EUT, within the definition of V3.3 of (draft) C63.17-2005. The maximum base EUT antenna gain is 3dBi. The antennas are elliptically polarized with the major axis of polarization vertical from the top left and right corners of the base, and with the minor axis of polarization normal to the front and back surfaces of the base for left and right antennas. Maximum peak power level Maximum specified peak conducted power level for both the base and the remote EUT is +4dBm. Emission bandwidth Emission bandwidth measured according to the procedures of V3.3 (draft) C63.17-2005 clause 6.1.3 for the base EUT is 1.47MHz. Emission bandwidth measured according to the procedures of V3.3 (draft) C63.17-2005 clause 6.1.3 for the remote unit EUT is 1.49MHz. Nominal receive bandwidth Nominal receive bandwidth is +/-500kHz. 3/182 Frame period and time slot plan, if TDMA techniques are used The EUT system is a TDMA system which “further divides access in time” in the context of clause 6.2.2 of V3.3 (draft) C63.17-2005. Frame period is 10mS. There are 24 timeslots per frame, with one of the first 12 timeslots used for the remote transmissions and one of the last 12 timeslots used for the base transmissions. Transmit and receive timeslots are 5mS apart in time. Transient events occur during which two non-adjacent timeslots may be in use by the base during the setup of the communications channel, or by both the base and the remote EUT as the system does a soft handoff in response to interference. Minimum and maximum burst length, if TDMA techniques are used Minimum burst length is 90uS, the beacon transmissions from the base when a communications channel is not open. Maximum burst length is 390uS, transmissions from the remote when a communications channel is open. Minimum and maximum operating temperature range declared to the end-user The minimum operating temperature is +4C. The maximum operating temperature is +44C. Whether a system built with the EUT does or does not operate under the provisions of 47CFR15.323(c)(10) to test for deferral only in conjunction with a companion device The EUT system does not use the provisions of 47CFR15.323(c)(10) to enable testing for access criteria only in one element of the system.

Clause 6.1 Emissions tests for the base EUT For the tests of clause 6.1 of V3.3 (draft) C63.17-2005, the test platform and base EUT are configured according to test configuration #1, Conducted emissions tests, base EUT, of section (I) of this document. The base EUT is established in a communications channel with the headset companion device by means of a radiative-coupled connection, though the base EUT is in conducted connection to the spectrum analyzer, per figure 3 of v3.3 (draft) C63.17-2005 in clause 6.1.1. Administrative commands are used to set the base to the desired carrier for the test.
