1.0 General Description

1.1 Product Description

The Equipment Under Test (EUT) is a transmitter of an RC Car operating at
49.860 MHz as dictated by a crystal. The EUT is powered by a 4.5 V DC
source (3 x 1.5V "AA" size batteries). The EUT has a left / right control lever, a
forward / backward control lever and a power ON/OFF switch.

After switching ON the EUT and the receiver of the RC Car, activating the
control levers on the EUT can control the receiver moving forward, backward,
left and right.

The Model: 1021361/6016876, 1023913/6018296, 1023915/6018296,
1023996/6018354, 1023999/6018357 and 1024001/6018360 are the
same as the Model: 44422 in hardware aspect. The difference in model
number and item name only.

Antenna Type : External, Integral

For electronic filing, the brief circuit description is saved with filename: descri.pdf.

1.2 Related Submittal(s) Grants

The Certification procedure of receiver for this transmitter (with FCC ID:
PQN44422RX49MHZ) is being processed as the same time of this application.

1.3 Test Methodology

Radiated emission measurements were performed according to the procedures
in ANSI C63.4 (2003). All radiated measurements were performed in an Open
Area Test Site. Preliminary scans were performed in the Open Area Test Site
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
radiated data is located at Garment Centre, 576 Castle Peak Road, Kowloon,
Hong Kong. This test facility and site measurement data have been placed on
file with the FCC.

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 3 X new 1.5V “AA” size batteries.
For maximizing emissions, 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 reported 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 mounted to a plastic stand
if necessary and placed on the wooden turntable, which enabled the engineer to
maximize emissions through its placement in the three orthogonal axes.

2.2 EUT Exercising Software

There was no special software to exercise the device. Once the unit is powered
up, it transmits the RF signal continuously.

2.3 Special Accessories
There are no special accessories necessary for compliance of this product.

2.4 Equipment Modification
Any modifications installed previous to testing by Spin Master Toys Far East
Limited will be incorporated in each production model sold/leased in the United
States.
No modifications were installed by Intertek Testing Services Hong Kong Ltd.

2.5 Measurement Uncertainty
When determining of the test conclusion, the Measurement Uncertainty of test
has been considered.

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.

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), Average Factor (optional) from the
measured reading. The basic equation with a sample calculation is as follows:
FS = RA + AF + CF - AG - 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
AV = Average Factor 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 - AV 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 are added. The amplifier gain of 29 dB and
average factor of 5 dB are subtracted, giving a field strength of 27 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 RR = 18.0 dBµV
CF = 1.6 dB LF = 9.0 dB
AG = 29.0 dB
AV = 5.0 dB
FS = RR + LF
FS = 18 + 9 = 27 dBµV/m

Level in µV/m = Common Antilogarithm [(27 dBµV/m)/20] = 22.4 µV/m

NOTES: 1. Peak Detector Data unless otherwise stated.

2. All measurements were made at 3 meters. Harmonic emissions not
detected at the 3-meter distances 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 sign in the column shows value below limit.

4. Horn antenna is used for the emissions over 1000MHz.

8.0 Miscellaneous Information

This miscellaneous information includes details of the measured bandwidth.

8.1 Measured Bandwidth

The plot saved in bw.pdf which shows the fundamental emission is confined in
the specified band. The field strength of any emission appearing between the
band edges and up to 10kHz above and below the band edges (49.81 and
49.91 MHz) is at least 35.68 dB below the carrier level. And at 49.81 & 49.91
MHz, there are at least 26 dB below the carrier level. It meets requirement of
Section 15.235(b).

8.2 Discussion of Pulse Desensitization

Pulse desensitivity is not applicable for this device. Since the transmitter
transmits the RF signal continuously.

8.3 Calculation of Average Factor

The average factor is not applicable for this device as the transmitted signal is a
continuously signal.

8.4 Emissions Test Procedures

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.
