American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 August 29, 2002 RE: FCC ID: K9L1300RE Attention: Brian Haghtalab I have a few comments on this Application. 1 The 731 says this is a part 15.121 device. Please note 15.121 is for scanning receivers and this is a superregenerative receiver. The Eq code is CRR. This is FYI, no action is needed on this item. 2 The conducted emissions setup photo does not show the LISN setup. Please provide a photo showing ANSI C63.4 setup for conducted. 3 Label information needs to state what the label is made of and how it is affixed. Please include this information with the label sample. 4 The test was done incorrectly and not in accordance with the currently accepted ANSI C63.4 section 12.1.1.1 (Superregenerative receiver). Please note that this section SPECIFICALLY STATES THAT THE COHERED SIGNAL IS TO BE FROM A SIGNAL GENERATOR, NOT THE MATCHING TRANSMITTER. Please note that you used a matching transmitter for this test. Please retest the unit using the required cohering signal specified in ANSI C63.4.

The Equipment Under Test (EUT) was the Models: SKY-1310E, 1310PE, 1315E, 1315GE, 1320E, 1321E, 1410E Remote Control Receiver. Radio-Noise Emissions tests were performed according to the ANSI C63.4- 1992, “Method of Measurement of RFI from Low-Voltage Electronic Equipment in the Range of 9 KHz- 40 GHz”. The measuring equipment conforms to ANSI C63.2 Specifications for electromagnetic Noise and Field Strength-Instrumentation. Test was performed at National Certification Laboratory in Ellicott City, MD. Site description and site attenuation data have been placed on file with the FCC’s sampling and Measurements Branch. FCC acceptance was granted on May 26, 1993. 1.1 Summary The Models: SKY- 1310E, 1310PE, 1315E, 1315GE, 1320E, 1321E, 1410E Remote Control Receiver, complies with the Part 15.109 Radio Limits for an Unintentional Radiator. All models have identical electronic circuit design. Differences are the type of 120 VAC connector implemented, as described in the filing. 2.0 Description of Equipment Under Test (EUT) The EUT Features: FEATURES FREQUENCY Internal PCB Antenna303.65.00 MHz Superregenerative Design Appliance Switch Application 120 VAC Operation FCCID: K9L1300RE 3 3.0 Test Configuration The EUT was setup on the test table in a manner which follows the general guidelines of ANSI C63.4, Section 6 “General Operating Conditions and Configurations.” Tests were performed by exercising the receiver with a CW RF signal level of –20 dBm into a whip antenna from a signal generator. A lamp load was connected to the EUT during testing. The EUT was configured in 3 orthogonal positions to determine the maximum RF level at each emission frequency. The data tables give the EUT position designation that produces worst-case field strength, in an X, Y, Z system. This is described below: 4.0 Conducted Emissions Scheme The EUT is placed on an 80 cm high 1 X 1.5 meter non-conductive table. Power to the CPU is provided through a Solar Corporation 50 Ω/50 μH line Impedance Stabilization Network bonded to a 2.2 X 2 meter horizontal ground plane, and a 2.2 X 2 meter vertical ground plane. The LISN has its AC input supplied from filtered AC power source. A separate LISN provides AC power to the peripheral equipment. I/O cables are moved about to obtain maximum emissions. The 50Ω output of the LISN is connected to the input of the spectrum analyzer and emissions in the frequency range of 450 kHz to 30 MHz are searched. The detector function is set to quasi- peak and the resolution bandwidth is set at 9 kHz, with all post-detector filtering no less than 10 times the resolution bandwidth for final measurements. All emissions within 20 dB of the limit are recorded in the data tables. 5.0 Radiated Emissions Scheme The EUT was initially scanned in the frequency range 30 to 3040 MHz indoors, at a distance of one (1) meter to determine its emissions profile. The EUT was then placed on an 80 cm high 1 X 1.5 meter non-conductive motorized turntable for radiated testing on the 3-Meter open area test site. The emissions from the EUT are measured continuously at every azimuth by rotating the FCCID: K9L1300RE 4 turntable. Waveguide horn and log periodic broadband antennas are mounted on an antenna mast to determine the height of maximum emissions. The height of the antenna is varied between one (1) and four (4) meters. Both the horizontal and vertical field components are measured. The output from the antenna is connected to the input of the spectrum analyzer. The detector function is set to Peak. All emissions within 20 dB of the limit are recorded in the data table. Measurements from 30-1000 MHz:The output from the antenna is connected to the input of the spectrum analyzer. The detector function is set to Quasi-Peak. The resolution bandwidth of the spectrum analyzer system is set at 120 kHz for the range 30-1000 MHz with all post- detector filtering no less than 10 times the resolution bandwidth. Measurements from 1-4 GHz:The output from the horn antenna is connected to the input of a 30 dB pre-Amp, which is in turn attached to the spectrum analyzer. The detector function is set to Peak. The resolution bandwidth of the spectrum analyzer system is set at 1 MHz for the range 1-4 GHz. To convert the spectrum analyzer reading into a quantified E-field level to allow comparison with the FCC limits. It is necessary to account for various calibration factors. These factors include cable loss (CL) and antenna factors (AF). The AF/CL in dB/m is algebraically added to the Spectrum Analyzer voltage in dBμV/m. This level is then compared with the FCC limit.
