Tx Mode#
Test Method:
For emission measurements at or below 1 GHz, the sample was placed 0.8m above the ground plane of semianechoic Chamber*. For emission measurements above 1 GHz, the sample was placed 1.5m above the ground
plane of semi-anechoic Chamber*. Measurements in both horizontal and vertical polarities were performed.
During the test, each emission was maximized by: having the EUT continuously working, investigated all
operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position,
manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal
and vertical polarizations. In the frequency range of 9kHz to 30MHz, The center of the loop antenna shall be 1
meter above the ground and rotated loop axis for maximum reading. The emissions worst-case are shown in Test
Results of the following pages.
Remark: 3 orthogonal axis apply to hand-held device only.

Conditions of Issuance of Test Reports
1.
All samples and goods are accepted by The Hong Kong Standards & Testing Centre Limited (the “Company”) solely
for testing and reporting in accordance with the following terms and conditions. The Company provides its
services on the basis that such terms and conditions constitute express agreement between the Company and

The Company will not be liable for or accept responsibility for any loss or damage howsoever arising from the use
of information contained in any of its Reports or in any communication whatsoever about its said tests or
investigations.
8.
Clients wishing to use the Report in court proceedings or arbitration shall inform the Company to that effect prior
to submitting the sample for testing.
9.
Subject to the variable length of retention time for test data and report stored hereinto as to otherwise specifically
required by individual accreditation authorities, the Company will only keep the supporting test data and
information of this test report for a period of three years. The data and information will be disposed of after the
aforementioned retention period has elapsed. Under no circumstances shall we provide any data and information
which has been disposed of after the retention period. Under no circumstances shall we be liable for damages of
any kind, including (but not limited to) compensatory damages, lost profits, lost data, or any form of special,
incidental, indirect, consequential or punitive damages of any kind, whether based on breach of contract of
warranty, tort (including negligence), product liability or otherwise, even if we are informed in advance of the
possibility of such damages.
