1.3 Test

Methodology

Radiated emission measurements were performed according to the
procedures in ANSI C63.4 (2003). Radiated Emission measurement was
performed in Open Area Test Sites. Preliminary scans were performed in the
Open Area Test Sites only to determine worst case modes. All Radiated tests
were performed at an antenna to EUT distance of 3 meters, unless stated
otherwise in the

"Justification Section"

of this Application.

1.4 Test

Facility

The open area test site and conducted measurement facility used to collect
the radiated data is located at Garment Centre, 576 Castle Peak Road,
Kowloon, Hong Kong. This test facility and site measurement data have been
fully placed on file with the FCC.
