These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna - Increase the separation between the equipment and receiver - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected - Consult the dealer or an experienced radio/TV technician for help Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. RSS-210 Compliance Statement: This device complies with Industry Canada Licence-exempt RSS-210. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada,. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Technical Description The Equipment Under Test (EUT), is a portable 2.4GHz Transmitter (Controller Unit) for a RC car. The sample supplied operated on 71 channels, normally at 2405 - 2475MHz. The channels are separated with 1MHz spacing. The EUT is powered by 1 x 9.0V Alkaline battery. After switching on the EUT, the car will be moved forward or backward and turned left and right based on the switches pressed in the controller. Antenna Type: External, Whip Antenna Antenna Gain: 0dBi Nominal rated field strength is 96.9dBμV/m at 3m Maximum allowed production tolerance: +/- 3dB The brief circuit description is listed as follows: 1. U1 (RS14132-TX) acts as MCU 2. Y1 acts as 12MHz Oscillator 3. C1, C2 and L1 act as antenna matching circuit

Analysis Report The Equipment Under Test (EUT), is a portable 2.4GHz Transmitter (Controller Unit) for a RC car. The sample supplied operated on 71 channels, normally at 2405 - 2475MHz. The channels are separated with 1MHz spacing. The EUT is powered by 1 x 9.0V Alkaline battery. After switching on the EUT, the car will be moved forward or backward and turned left and right based on the switches pressed in the controller. Antenna Type: External, Whip Antenna Antenna Gain: 0dBi Nominal rated field strength is 96.9dBμV/m at 3m Maximum allowed production tolerance: +/- 3dB According to the KDB 447498: Based on the maximum average field strength of production tolerance was 99.9dBμV/m at 3m in frequency 2.475GHz. Thus, it below calculated field strength according to minimum SAR exclusion threshold level as follows: The worst case of SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt (freq. in GHz) = 3.0 * 5 / sqrt (2.483.5) mW = 9.52 mW According to the KDB 412172 D01: EIRP = [(FS*D) ^2*1000 / 30] Calculated Field Strength for 9.52mW is 105dBuV/m @3m Since maximum average field strength plus production tolerance < = 105dBuV/m @3m and antenna gain is > = 0.0dBi, it is concluded that maximum Conducted Power and Field Strength are well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
