Each FreeLinc adapter is compatible with other FreeLinc commu- nications accessories that use cutting-edge LibertyLink™ wire- less technology from Aura Communications, Inc. Based on near- field magnetic induction communication (NFMC), LibertyLink supports mobility, freedom-of-motion, exceptional battery life, audio integrity, ease-of-use, durability, secure communications and comfort. LibertyLink is the first technology of its kind to be implemented into practical voice and audio solutions. FreeLinc communications accessories operate in a “bubble” that envelops one to three meters of each user’s personal space, and is – by the laws of physics – fully private and secure. The result is an easier to use, lower cost system that makes far more efficient use of power and bandwidth than conventional RF systems. By limiting the range and bandwidth to only what the applica- tion requires, the product achieves a very substantial savings in power. Signals are designed to propagate only within a two- meter range, enabling a huge power and battery advantage (up to six times) over standard RF technology. Thank you for choosing FreeLinc.

On another note, Roland's final review of the FCC labels and User manuals indicate that neither of them carries the label text required in 15.19(a)(3): "This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation." When the device is smaller than the palm of a normal hand (as it is in these cases), it is permissible to delete the text from the FCC ID label and place it in the User manual. Similar text is now present in the User manuals, but it is not identical to the text above. Please resolve this issue as soon as possible. Regards, Terre -----Or…

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. 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 AF = 7.4 dB/m CF = 1.6 dB AG = 29.0 dB FS = 32 dBμV/m Level in μV/m = [10( 32 dBμV/m)/20] = 39.8 μV/m The following is how net line-conducted readings were determined: NF = RF + LF + CF + AF Where NF = Net Reading in dBμV RF = Reading from receiver in dBμV LF = LISN Correction Factor in dB CF = Cable Correction Factor in dB AF = Attenuator Loss Factor in dB To convert from dBμV to μV or mV the following was used: UF = 10 (NF / 20) where UF = Net Reading in μV Example: NF = RF + LF + CF + AF = 28.5 + 0.2 + 0.4 + 20.0 = 49.1 dBμV UF = 10 (48.1 dBμV / 20) = 254 μV/m EMI Report for Radeum on Model: Freelinc Wireless Headset System Report Number 3079725.EMI Page 6 of 21 3.1 Measurement Uncertainty Compliance of the product is based on the measured value. However, the measurement uncertainty is included for informational purposes.

They meet the technical requirements of ANSI C63.4-2003 and CISPR 22:1993/EN 55022:1994 for radiated and conducted emission measurements. The shelter structure is entirely fiberglass and plastic, with outside dimensions of 33 ft x 57 ft. The structure resembles a quonset hut with a center ceiling height of 16.5 ft. The testing floor is covered by a galvanized sheet metal groundplane that is earth-grounded via copper rods around the perimeter of the site. The joints between individual metal sheets are bridged with a 2 inch wide metal strips to provide low RF impedance contact throughout. The sheets are screwed in place with stainless steel, round-head screws every three inches. Site illumination and HVAC are provided from beneath the ground reference plane through flush entry ports, the port covers are electrically bonded to the ground plane. A flush metal turntable with 12 ft. diameter and 5000 lb. load capacity (12,000 lb. in Site 3) is provided for floor-standing equipment. A wooden table 80 cm high is used for table-top equipment. The turntable is electrically connected to the ground plane with three copper straps. The straps are connected to the turntable at the center of it with ground braid. T…
