Applicant: Plantronics Inc. Model: WH500 FCC ID: AL8-WH500 IC: 457A-WH500 DUT Type: Portable UPCS/LE-PCS DECT Wireless Headset Freq. Range: 1921.536 - 1928.448 MHz 2010 Celltech Labs Inc. This document is not to be reproduced in whole or in part without the prior written permission of Celltech Labs Inc. Page 1 of 3 RFx Exhibit Serial No. 051810AL8-T1020-S15D RFx Exhibit Issue Date June 18, 2010 RFx Exhibit Revision No. Rev. 1.1 (2nd Release) Test Lab Certificate No. 2470.01 FCC RF EXPOSURE EXHIBIT Plantronics Model: WH500 DECT UPCS Wireless Headset FCC ID: AL8-WH500 Device Mode of Operation The system (base and headset together) can be unlinked, linked but with no voice path open (idle locked state) or linked with voice paths open. Unlinked is when the ends of the system are out of range. Linked but no voice path open is when the system is ready for use but no voice path is active (idle locked), and linked with voice paths open is when the system is in use for voice communication. Audio can be provided from the telephone and/or the USB interface. Transmission Mode The headset unit is mated with the base unit (subscribed to each other) under normal operation. The communications link is custom (double-slot) TDMA (UPCS standard), and is symmetrical; both ends of the link transmit using the same protocol. Maximum Duty Cycle Maximum Duty Cycle occurs when the headset and base are in a wideband audio link. Maximum duty cycle (wideband audio mode) is approximately 8.3%. For each end of the active link in wideband audio mode, a unit transmits for 2 out of 24 timeslots Æ 2:24 duty cycle. The DECT frame rate is 10ms, so each end of the link transmits for approximately 800 uS every 10ms when the system is linked and active. In narrowband audio mode, the duty cycle is exactly half that in wideband audio mode, so approximately 4.1%. When the system is linked but voice paths are not open (headset is “idle-locked” to the base) the base transmits with a 1.3% duty cycle (130uS every 10mS). In this mode the headset will transmit link maintenance information every thirty seconds. When unlinked and out of range (the headset cannot hear the base), the headset does not transmit, and the base transmits at a 1.3% duty cycle (130uS every 10mS). Two time slots are used for wideband audio, effectively doubling the duty cycle, minus idle time. Maximum RF Output Power Manufacturer’s Rated Maximum Peak Conducted Power = 19.7 dBm (93.3 mW) Manufacturer’s Specified Source-Based Time-Averaged Duty Cycle = 8.3% Max. Source-Based Time-Averaged Output Power = 8.9 dBm (7.8 mW) Device Operating Configuration(s) and Exposure Conditions The Plantronics WH500 Headset can be worn on either the left or right ear and is worn over-the-ear. The Plantronics WH500 Headset is intended for use within the General Population / Uncontrolled RF exposure environment. See photographs (next page) of device and antenna placement. Antenna-to-Ear Separation Distance 15 mm (manufacturer measurement) Analysis Summary Based on the transmission modes, operating configurations and maximum source-based time-averaged output power and duty cycle as described in this document, SAR compliance is demonstrated for the Plantronics WH500 DECT UPCS Headset without routine SAR measurements (in accordance with the FCC’s response to KDB Inquiry Tracking Number 309465).

Background EUT description The Wireless Headset WH500 are headsets which can receive and transmit audio to/from its companion Base assembly, WO1, FCC ID AL8WO1 . This document reports compliance of the headset to the test parameters of C63.17-2006. The headset EUT is capable of initiating a link in a normal mode of 60 channels and a Wide Band Audio Mode (WBM) which only supports 30 channels. The main sections of this report documents the normal mode operation in the high power setting. Appendix A documents the WBM compliance testing for any tests that do or may operate differently from the normal mode. The headset EUT also is capable of RF power control. Compliance to C63.17-2006 is documented in Appendix B which repeats any testing that may operate differently from maximum power mode, or affect the access threshold. The power control modes are fixed, or adaptive. Adaptive power control will allow the RF transmitter to adjust the output power from maximum to minimum in approximately 4-5dB steps. Fixed power mode does not allow power control. The user can select between adaptive or fixed but can not set the power range, this is done during EUT factory set up. The specific unit tested is headset SN: 05F9ED317. Manufacturer’s attestations, mandatory declarations and descriptions The Wireless Headset WH500 uses only digital modulation. Clause 4.11 in C63.17-2006 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 C63.17-2006. 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 headset EUT antenna gain is 3dBi. The antenna is elliptically polarized with the major axis of polarization parallel to the headband portion of the headset disposed away from the user’s head, and with the minor axis of polarization on the same plane as the electrical board and perpendicular headband portion of the headset. Maximum peak power level Maximum specified peak conducted power level for the headset EUTs is +20.0dBm. Minimum peak power level The maximum power level at the minimum RF power setting is specified peak conducted power level for the headset EUTs is +4.0dBm. Emission bandwidth Emission bandwidth measured according to the procedures of C63.17-2006 clause 6.1.3 for the headset EUT is 1.45MHz. Nominal receive bandwidth Nominal receive bandwidth is +/-500kHz. 4/125 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 C63.17- 2006. Frame period is 10mS. There are 24 timeslots per frame, with one of the first 12 timeslots used for the headset transmissions and one of the last 12 timeslots used for the base transmissions. Transmit and receive timeslots are 5mS apart in time. The headset can also be set to wideband audio mode (WBM) which uses 2 of the 12 timeslots for headset transmissions and 2 of the timeslots for headset receipt. 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 headset 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 390uS, transmissions from the headset when a communications channel is open. Maximum burst length is 780uS, transmissions from the headset when a communications channel is open. Minimum and maximum operating temperature range declared to the end-user The minimum operating temperature is 0C.…
