TEST REPORT Report No. : AJ027378-001 Date : 2007 November 22 1 General Information 1.1 General Description The equipment under test (EUT) is a transmitter for Sand Hero. It operates at 27.145MHz and the oscillation of radio control is generated by a crystal. The EUT is powered by 1 x 9V size battery. There are two control sticks on the EUT. When the forward, backward, turn right or turn left stick is pushed, it will transmit different radio control signal to the receiver. The brief circuit description is listed as follows: - Q1 and associated circuit act as a RF amplifier. - U1, X1 and associated circuit act as an encoder and an oscillator. - D2 and associated circuit act as a voltage regulator.

TEST REPORT Report No. : AJ027378-001 Date : 2007 November 22 2 Description of the radiated emission test 2.1 Test Procedure Radiated emissions measurements are investigated and taken pursuant to the procedures of ANSI C63.4 – 2003. The equipment under test (EUT) was placed on a non-conductive turntable with dimensions of 1.5m x 1m and 0.8m high above the ground. 3m from the EUT, a broadband antenna mounting on the mast received the signal strength. The turntable was rotated to maximize the emission level. The antenna was then moving along the mast from 1m up to 4m until no more higher value was found. Both horizontal and vertical polarization of the antenna were placed and investigated. For below 30MHz, a loop antenna with its vertical plane is placed 3m from the EUT and rotated about its vertical axis for maximum response at each azimuth about the EUT. And the centre of the loop shall be 1 m above the ground. The device was rotated through three orthogonal axes to determine which attitude and configuration produce the highest emission during measurement. 2.2 Test Result Peak Detector data was measured unless otherwise stated. “#” means emissions appearing within the restricted bands shall follow the requirement of section 15.205. It was found that the EUT meet the FCC requirement. Page 6 of 11 FCC ID: QEASANDHERO27T This document shall not be reproduced except in full or with written approval by the laboratory.

TEST REPORT Report No. : AJ027378-001 Date : 2007 November 22 5 Supplementary document The following document were submitted by applicant, and for electronic filing, the document are saved with the following filenames: Document Filename ID Label/Location LabelSmp.jpg Block Diagram BlkDia.pdf Schematic Diagram Schem.pdf Users Manual UserMan.pdf Operational Description OpDes.pdf 5.1 Bandwidth The plot on saved in TestRpt2.pdf shows the fundamental emission is confined in the specified band. It also shows that the band edge met the 15.209 requirement at 26.9599 and 27.2801 MHz. 5.2 Duty cycle The duty cycle is simply the on-time divided by the period: The duration of one cycle = 31.72ms Effective period of the cycle = 0.95ms x 8 + 0.48ms x 18 = 16.24ms Duty Cycle = 16.24ms / 31.72ms = 0.51 Therefore, the average factor is found by 20 log10 0.51 = -5.8dB 5.3 Transmission time Not Applicable 5.4 Power Spectral Density Not Applicable Page 10 of 11 FCC ID: QEASANDHERO27T This document shall not be reproduced except in full or with written approval by the laboratory.
