KTL OttawaFCC PART 15, SUBPART B RADIO RECEIVERS PROJECT NO.: 8R00987 EQUIPMENT: Sony SPP-900 Analog 900 MHz Cordless Telephone Page 8 of 30 Justification The E.U.T. was configured for testing as per typical installation. Position and bundling of cables were investigated to establish maximum amplitude of emissions. The following combinations were investigated to establish worst case configuration: BASE: 3-Orthagonal Orientations (1) Lying flat on the table, antenna pointing up. (2) Lying flat on the table, antenna pointing straight back. (3) Vertically mounted, antenna pointing up. HANDSET: 3-Orthagonal Orientations (1) Lying flat on its back. (2) Vertical (3) Lying on its side. Exercise Program The E.U.T. exercise program used during radiated and conducted testing was designed to exercise the various system components in a manner similar to typical use. Exercise mode: (1) Off hook, loaded telephone line, carrier enabled. KTL…
