O5UKS110BPC to Stereo Link Base Station

Akoo.com Kima operating instructions: The Kima system allows you to listen to music over the Internet on your home stereo system or FM radio. The Remote unit allows you to either directly connect to your stereo with RCA type cables or to retransmit the music over the FM band at 88.1 or 88.3 MHz. Use Instructions: 1) Connect the Audio out of your PC sound card, CD player or similar device to the Audio Input of the Kima Base unit. 2) Place the Kima Remote unit up to 1000 feet away, within 10 feet of your FM radio to use the FM transmitter function or connect the Stereo out connection of the Remote unit to the Audio In of your stereo receiver. 3) If you wish to use the FM transmitter feature, tune your radio to the same station as the Kima Remote unit is set to, either 88.1MHz or 88.3MHz. Battery Power: The Kima Base and Remote units can be powered either from a 6 Volt AC Adapter or from 4 AAA type batteries. NOTE: This device complies with part 15 of the FCC Rules.

TEST PROCEDURES. Radiated test procedure The EUT, associated cables and peripheral devices are placed on the supporting table and any support equipment is placed off the site. The EUT is turned on and any necessary operating or test software installed and allowed to warm up. The frequency band from 30 MHz to 40 GHz is scanned. When an emission is found the emission is maximized by varying the bundle position of the connecting cables, the antenna height, the antenna polarization (vertical and horizontal) and the table orientation (360 degrees). The maximum reading is recorded and the next signal is searched for. Conducted test procedure The power line of the EUT is connected to the LISN (Line Impedance Stabilization Network). A measurement of the emissions are made from the power line for both phase and neutral on the analyzer in the frequency range from 450 kHz to 30 MHz. The maximum readings are recorded for each phase. All measurements are made according to the procedures defined in: "ANSI C63.4-1992 Standard Methods of Measurement of Radio Noise Emissions from Low-Voltage Electrical and Electronics Equipment in the Range of 9 kHz to 40 GHz, American National Standard for (ISBN 1- 55937-215-5).

Thanks and Best Regards, Clifton P. Brick FCC ID# O5UKS110B 1. For your information only: The DCD code on the 731 form item 6(a) is only for transmitters below 1705 kHz, not 1705 MHz as you have indicated. I am considering this device to be a DXX Low Power Communications Device Transmitter. No response is needed to this item. Thank You. 2. A shielded cable was used during test on the audio port of the device. 15.27(c) requires that either such a cable be shipped with the device or that the user's manual inform the user of the requirement to use shielded cables on the audio input port. Please add a suitable statement to the user's manual or tell us that an shielded audio cable is shipped with the unit. An appropriate statement was added, please see the attached revised instruction. 3. You state on page 13 of the test report that a video bandwidth of 300KHz was used. Did you use this VBW with above 1GHz where a Resolution Bandwidth of 1MHz is required or did you use a different VBW above 1GHz? The bandwidth of 1MHz was used above 1GHz. Page 2 of 3 Compliance Worldwide, Inc. - 357 Main Street - Sandown, NH 03873 (603) 887 3903 Fax 887 6445 http://www.cw-inc.com 4. Your tabular data for radiated emissions says the units are dBuV. Shouldn't these be reported in units of dBuV/m? How do you account for antenna factor? If your instrument automatically adds in the antenna factor, do you also include a cable loss factor? What about the preamp? You are correct, the data is actually in dBuV/m . Antenna factors are added automatically via an amplitude correction file. Cable loss is compensated automatically via an amplitude correction file. The preamp is internal to the instrument and is compensated automatically. 5. Please confirm that the antenna is directly soldered to the PC board and that there is no connector in line with the antenna. If there is a connector describe how it meets the unique connector requirements of 15.203. Yes, the antenna is soldered directly to the PCB. 6. I think there is another PCB within the chassis. If there is, please submit photos of both sides of any circuit boards not already submitted in the test report. The schematic diagrams list an “LED_PCB". This was an oversight, please find the photos attached. 7. Please confirm that the label is "permanently attached" and tell us the method. Please confirm that the point size of the typeface used is larger than 8pt. The Label will be molded into the rear housing and the font will meet the required minimum. See photo attached. 8. 15.31(e) requires that the power input to the device be varied from 85% to 115% of nominal while the effect on fundamental radiated emissions field strength. Please tell me where this is covered in your test report or submit data showing that the effect of power variations on the unit's fundamental emission. The units operate on 3V regulated DC at the board level. The input voltage was varied +/- 15% and no output power change was noted.

I would have expected data for at least the second and third. Please confirm that there is no data and if that is the case, please submit your noisefloor reading in field strength at the measurement distance to confirm that you can observe to the limit level. Please find attached a plot of my OATS ambient in the range requested. 10. In future submissions please send the equipment photos as two separate exhibits labeled exterior and interior photos. I will extract them from this application and submit them separately this time. The FCC wants me to submit them as separate files. No Problem.
