II. Unit Tested:
The International Electronics, Inc. HeadOn wireless headset earpiece is the portion of the wireless
headset worn on the user. The HeadOn uses DC power and has a digitally modulated 916 MHz
transmitter and receiver. It consists of the three-piece plastic enclosure with speaker hardware, the
transmit/receive circuits, the electronics, and the antenna. The table below describes the unit tested
to determine compliance with the standards:

The highest frequency investigated is ten times the HeadOn highest fundamental (9.16 GHz).
III. Measurement Location:
The GME laboratory and Open Area Test Site (OATS) are located at 219 Blake Roy Road,
Middlebury, VT. The OATS is a 3-meter site complete with antenna positioner, ground plane and
motorized turntable. The OATS is constructed in accordance with ANSI C63.7-1992 and complies
with the requirements for radiated emissions testing in ANSI C63.4-2000 and CISPR 16-1993.
The electromagnetic laboratory is constructed in accordance with CE immunity standards and ANSI
C63.4-2000 (conducted emissions).
GME is internationally accredited by the American Association for Laboratory Accreditation
(A2LA) and meets the quality requirements in ISO/IEC 17025 (1999), "General Requirements for
the Competence of Testing and Calibration Laboratories."

VI. Equipment and Cable Configuration:
GME witnessed the unit in satisfactory condition for testing, however the manufacturer is
responsible for ensuring that the equipment under test (EUT) represents the product line. The
manufacturer is also responsible for the EMC test plan and for assuring that this report is
consistent with that plan. The EUT configuration was arranged to produce maximum radiated
emissions as shown in the block diagram below, as well as in the photograph in Section VIII. The
equipment was subjected to complete emissions tests.

7. Exposure Evaluation.
The analysis below compares the measured power to the maximum permissible exposure limit for
general population with uncontrolled access. The unit can be used continuously, no special
averaging time or limit relaxations are employed. Maximum peak available power is used in
calculations.
Unit Frequency : 916.4 MHz
Unit Maximum Average Power .0001 Watt measured/ available
Standard user weight : 100 kg
Specific Absorption Rate (SAR) Limit for whole-body: 0.08 W/kg
Specific Absorption Rate (SAR) Limit for one-gram tissue volume: 1.6 W/kg
SAR Whole body = 100kg * .0001 W = 0.01 W/kg for HeadOn earpiece
SAR 1g tissue = .001 kg * = 0.000001W/kG for HeadOn earpiece
In addition per IEEE C95.1 paragraph 6.10 (2): low power devices are unlikely to expose users in
excess of the criteria when power is less than or equal to:
Pmax = 1.4 * (450/f) Watts where f is in MHz.
Pmax is significantly greater than the power available at the HeadOn:
Pmax = 1.4 * (450/916.4) = 0.687 W.
