INTERTEK TESTING SERVICES EXHIBIT 1 GENERAL DESCRIPTION FCC ID: PQN44164TX27195 1

INTERTEK TESTING SERVICES 1.0 General Description 1.1 Product Description The equipment under test (EUT) is a transmitter for a RC helicopter operating at 27.195 MHz which is controlled by crystal. The EUT is powered by a 9V battery. The EUT has an ON/OFF switch and two control sticks. After switched ON the EUT, the left control stick is used to control the RC helicopter to rise and down. The right control stick is used to control the RC helicopter flying in forward, backward, left and right directions. The brief circuit description is saved with filename : descri.pdf 1.2 Related Submittal(s) Grants The receiver for this transmitter is exempted from the Part 15 technical rules per 15.101(b). FCC ID: PQN44164TX27195 2

INTERTEK TESTING SERVICES 1.3 Test Methodology The radiated emission measurements were performed according to the procedures in ANSI C63.4 (2003). 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. All Radiated tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the "Justification Section" of this Application. 1.4 Test Facility The open area test site and conducted measurement facility used to collect the emission 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: PQN44164TX27195 3

INTERTEK TESTING SERVICES EXHIBIT 2 SYSTEM TEST CONFIGURATION FCC ID: PQN44164TX27195 4

INTERTEK TESTING SERVICES 2.0 System Test Configuration 2.1 Justification The system was configured for testing in a typical fashion (as a customer would normally use it), and in the confines as outlined in ANSI C63.4 (2003). The EUT was powered by a new 9V battery during test. For maximizing emissions below 30 MHz, the EUT was rotated through 360°, the centre of the loop antenna was placed 1 meter above the ground, and the antenna polarization was changed. For maximizing emission at and above 30 MHz, the EUT was rotated through 360°, the antenna height was varied from 1 meter to 4 meters above the ground plane, and the antenna polarization was changed. This step by step procedure for maximizing emissions led to the data report in Exhibit 3.0. The unit was operated standalone and placed in the center of the turntable. The equipment under test (EUT) was configured for testing in a typical fashion (as a customer would normally use it). The EUT was placed on a turn table, and the Antenna of EUT was fully extended, which enabled the engineer to maximize emissions through its placement in the three orthogonal axes. For simplicity of testing, the unit was wired to transmit continuously. 2.2 EUT Exercising Software There was no special software to exercise the device. 2.3 Special Accessories There are no special accessories necessary for compliance of this product.

INTERTEK TESTING SERVICES EXHIBIT 3 EMISSION RESULTS FCC ID: PQN44164TX27195 7

INTERTEK TESTING SERVICES 3.0 Emission Results Data is included 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: PQN44164TX27195 8

INTERTEK TESTING SERVICES 3.1 Field Strength Calculation The field strength is calculated by adding the reading on the Spectrum Analyzer to the factors associated with preamplifiers (if any), antennas, cables, pulse desensitization and average factors (when specified limit is in average and measurements are made with peak detectors). A sample calculation is included below. FS = RA + AF + CF - AG + PD + AV 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 PD = Pulse Desensitization in dB AV = Average Factor in -dB In the radiated emission table which follows, the reading shown on the data table may reflect the preamplifier gain. An example of the calculations, where the reading does not reflect the preamplifier gain, follows: FS = RA + AF + CF - AG + PD + AV FCC ID: PQN44164TX27195 9

INTERTEK TESTING SERVICES 3.1 Field Strength Calculation (cont’d) Example Assume a receiver reading of 62.0 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. The pulse desensitization factor of the spectrum analyzer was 0 dB, and the resultant average factor was -10 dB. The net field strength for comparison to the appropriate emission limit is 32 dBμV/m. This value in dBμV/m was converted to its corresponding level in μV/m. RA = 62.0 dBμV AF = 7.4 dB CF = 1.6 dB AG = 29.0 dB PD = 0 dB AV = -10 dB FS = 62 + 7.4 + 1.6 - 29 + 0 + (-10) = 32 dBμV/m Level in µV/m = Common Antilogarithm [(32 dBμV/m)/20] = 39.8 μV/m FCC ID: PQN44164TX27195 10

Peak Detector Data unless otherwise stated. 2. All measurements were made at 3 meter. Harmonic emissions not detected at the 3 meter distance were measured at 0.3 meter and an inverse proportional extrapolation was performed to compare the signal level to the 3 meter limit. No other harmonic emissions than those reported were detected at a test distance of 0.3 meter. 3. Negative value in the margin column shows emission below limit. 4. Loop antenna is used for the emissions below 30 MHz. 5. Horn antenna is used for the emissions over 1000MHz. *Emission within the restricted band meets the requirement of part 15.205. The corresponding limit as per 15.209 is based on Quasi peak detector data for frequencies below 1000 MHz and peak detector data with average factor for frequencies over 1000 MHz.

INTERTEK TESTING SERVICES 8.2 Emissions Test Procedures The following is a description of the test procedure used by Intertek Testing Services in the measurements of transmitters operating under Part 15, Subpart C rules. The test set-up and procedures described below are designed to meet the requirements of ANSI C63.4 - 2003. The transmitting equipment under test (EUT) is placed on a wooden turntable which is four feet in diameter and approximately one meter in height above the ground plane. The antenna of EUT was fully extended. During the radiated emissions test, the turntable is rotated and any cables leaving the EUT are manipulated to find the configuration resulting in maximum emissions. The antenna height and polarization are varied during the testing to search for maximum signal levels. Detector function for radiated emissions is in peak mode. Average readings, when required, are taken by measuring the duty cycle of the equipment under test and subtracting the corresponding amount in dB from the measured peak readings. The frequency range scanned is from the lowest radio frequency signal generated in the device which is greater than 9 kHz to the tenth harmonic of the highest fundamental frequency or 40 GHz, whichever is lower. For line conducted emissions, the range scanned is 150 kHz to 30 MHz. FCC ID: PQN44164TX27195 26

INTERTEK TESTING SERVICES 8.2 Emissions Test Procedures (cont'd) The EUT is warmed up for 15 minutes prior to the test. AC power to the unit is varied from 85% to 115% nominal and variation in the fundamental emission field strength is recorded. If battery powered, a new, fully charged battery is used. Conducted measurements are made as described in ANSI C63.4 - 2003. The IF bandwidth used for measurement of radiated signal strength was 10 kHz for emission below 30 MHz and 120 kHz for emission from 30 MHz to 1000 MHz. Transmitter measurements are normally conducted at a measurement distance of three meters. However, to assure low enough noise floor in the restricted bands and above 1 GHz, signals are acquired at a distance of one meter or less. All measurements are extrapolated to three meters using inverse scaling, but those measurements taken at a closer distance are so marked. 1. When determining the test result, the Measurement Uncertainty of the test has been considered. 2. This test report is issued to the Company indicated based on the request of the Applicant of the product mentioned in this report. FCC ID: PQN44164TX27195 27
