The unit is capable of either tone or pulse dialing. The internal power supply's isolation is accomplished through a power transformer having an adequate dielectric rating. The circuit wiring is consistent under the requirement of part 68. The handset unit consists of a keypad with twelve standard keys (0,...9,*,#), four function keys (Program, Memory, Flash, Redial), and one channel switch key. A talk key is provided to control pick/release telephone line in a toggle base. The base unit has a page key, which is used to page the handset unit. The circuit description is saved with filename: descri.pdf Connection between the device and the telephone network is accomplished through the use of USOC RJ11C in the 2-wire loop calling central office line. 1.2 Purpose of Application The purpose of this application is to change the SAW filters of previously certified equipment to matched dielectric band-pass filters for solving the component shortage issue and a buffer amplifier is added to the VCO output to improve the isolation in order to reduce the pulling effect. The modification list is saved with filename: mod.pdf FCC ID: LBBFF915TE 2 INTERTEK TESTING SERVICES 1.3 Related Submittal(s) Grants This is an Application for Class II Permissive Change of a cordless telephone system. Two transmitters are included in this Application. This specific report details the emission characteristics of each transmitter. The receivers are subject to the verification authorization process, in accordance with 15.101(b). A verification report has been prepared for the receiver sections of each device. The device is also subject to Part 68 Registration. 1.4 Test Methodology Both AC mains line-conducted and radiated emission measurements were performed according to the procedures in ANSI C63.4 (1992). All measurements were performed in Open Area Test Sites. Preliminary scans were performed in the Open Area Test Sites only to determine worst case modes. For each scan, the procedure for maximizing emissions in Appendices D and E were followed. All Radiated tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the "Justification Section" of this Application. 1.5 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. FCC ID: LBBFF915TE 3 INTERTEK TESTING SERVICES EXHIBIT 2 SYSTEM TEST CONFIGURATION FCC ID: LBBFF915TE 4 INTERTEK TESTING SERVICES 2.0 System Test Configuration 2.1 Justification For emission testing, the equipment under test (EUT) was configured for testing in a typical fashion (as a customer would normally use it). During testing, all cables were manipulated to produce worst case emissions. The handset was powered by a fully charged battery. For the measurements, the EUT is attached to a cardboard box and placed on the wooden turntable. If the base unit attaches to peripherals, they are connected and operational (as typical as possible). The handset is remotely located as far from the antenna and the base as possible to ensure full power transmission from the base. Else, the base is wired to transmit full power without modulation. The signal is maximized through rotation and placement in the three orthogonal axes. The antenna height and polarization are varied during the search for maximum signal level. The antenna height is varied from 1 to 4 meters. Detector function is in peak mode. Radiated emissions are taken at three meters unless the signal level is too low for measurement at that distance. If necessary, a pre-amplifier is used and/or the test is conducted at a closer distance. All readings are extrapolated back to the equivalent three meter reading using inverse scaling with distance. Analyzer resolution is 100 kHz or greater. All emissions greater than 20 dBµV/m are recorded. Radiated emission measurement were performed from 30 MHz to tenth harmonics. 2.2 EUT Exercising Software The EUT exercise program used during radiated and conducted testing was designed to exercise the various system components in a manner similar to a typical use. For emissions testing, the units were setup to transmit continuously to simplify the measurement methodology. Care was taken to ensure proper power supply voltages during testing.

All the items listed under section 2.0 of this report are confirmed by: Confirmed by: Alfred Lo Senior Supervisor Intertek Testing Services Agent for Continental Conair Limited September 8, 1999 Signature Date FCC ID: LBBFF915TE 7 INTERTEK TESTING SERVICES EXHIBIT 3 EMISSION RESULTS FCC ID: LBBFF915TE 8 INTERTEK TESTING SERVICES 3.0 Emission Results Data is included of the worst case configuration (the configuration which resulted in the highest emission levels). A sample calculation, configuration photographs and data tables of the emissions are included. FCC ID: LBBFF915TE 9 INTERTEK TESTING SERVICES 3.1 Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain (if any) from the measured reading. The basic equation with a sample calculation is as follows: FS = RA + AF + CF - AG where FS = Field Strength in dBµV/m RA = Receiver Amplitude (including preamplifier) in dBµV CF = Cable Attenuation Factor in dB AF = Antenna Factor in dB AG = Amplifier Gain in dB In the following table(s), the reading shown on the data table reflects the preamplifier gain. An example for the calculations in the following table is as follows:- FS = RR + LF where FS = Field Strength in dBµV/m RR = RA - AG in dBµV LF = CF + AF in dB Assume a receiver reading of 52.0 dBµV is obtained. The antenna factor of 7.4 dB and cable factor of 1.6 dB is added. The amplifier gain of 29 dB is subtracted, giving a field strength of 32 dBµV/m. This value in dBµV/m was converted to its corresponding level in µV/m. RA = 52.0 dBµV/m AF = 7.4 dB CF = 1.6 dB AG = 29.0 dB FS = RR + LF FS = 23 + 9 = 32 dBµV/m RR = 23.0 dBµV LF = 9.0 dB Level in µV/m = Common Antilogarithm [(32 dBµV/m)/20] = 39.8 µV/m FCC ID: LBBFF915TE 10 INTERTEK TESTING SERVICES 3.2 Radiated Emission Configuration Photograph - Base Unit Worst Case Radiated Emission at 2715.300 MHz For electronic filing, the worst case radiated emission configuration photographs are saved with filename: base1.jpg and base2.jpg FCC ID: LBBFF915TE 11 INTERTEK TESTING SERVICES 3.3 Radiated Emission Data - Base Unit The data on the following pages list the significant emission frequencies, the limit and the margin of compliance.
