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 operating 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 in, 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 the 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 technician for help. This device complies with Part 15 of the FCC Rules and with RSS-210 of lndustry Canada. Operation is subject to the following two conditions: 1)This device may not cause harmful interference, and 2)This device must accept any interference received, including interference that may cause undesired operation. WARNING: Changes or modifications made to this equipment not expressly approved by the party responsible for compliance may void the FCC authorization to operate this equipment. RF Exposure Statement The TF-40 transmitter has been tested and meets the FCC RF exposure guidelines when used with the accessories supplied or designated for this product, and provided at least 20cm separation between the antenna the user\s body is maintained. Use of other accessories may not ensure compliance with FCC RF exposure guidelines.

The wavelength of the 2.4GHz is much shorter than that of the conventional frequencies, it is very susceptible to loss of signal which results in a receiving error. In order to avoid this phenomenon, please must follow the receiver antenna installation shown as below. . . RECEIVER’S ANTENNA INSTALLATIONRECEIVER’S ANTENNA INSTALLATION 4 Use this when performing left and right steering angle adjustments, throttle high side/brake side operation amount adjustment. - Corrects the maximum steering angle and left and right steering angles when there is a difference in the turning radius due to the characteristics, etc. of the vehicle. Maximum steering angle adjustment (The EPA function basically determines the maximum steering angle of each channel in each direction.) Adjustment: Range: 50~150% of each direction. Use the small plastic tool (-) to turn the two small knobs inside the control panel upper right as shown to make adjustments of the steering angle of each direction. (Caution: The servo reverse switches will effect to the directions) Caution! Decide the EPA value at the contact point of your vehicle steering system construction. When trim the EPA, be sure that the steering servo does not bind at the maximum steering angle. Throttle (forward, brake side/reverse side) adjustment. Adjustment: Range: 50~150% of each direction. Use the small plastic tool (-) to turn the plastic tool small knobs inside the control panel lower side as shown to make adjustments of the control range of each direction. (Caution: The servo reverse switches will effect to the directions) Caution! If the throttle channel is connected to an ESC, read your ESC manual to decide the EPA value for your vehicle. END POINT ADJUSTMENT / EPAEND POINT ADJUSTMENT / EPA 5 1. The antenna must be kept as straight up as possible. Otherwise it will reduce the effective range. 2. The antenna should be placed at 90 degrees to the receiver case. 3. The antenna must be kept away from conductive materials, such as metal and carbon by at least a half inch. The coaxial part of the antennas does not need to follow these guidelines, but do not bend it in a small radius. 4. Keep the antenna away from the motor, ESC, and other noise sources as much as possible. *This photo demonstrates how the antenna should be placed. For actual installation the receiver must be wrapped with a sponge or placed with floating material to protect it from vibration . The receiver contains precision electronic parts. It is the most delicate radio component on-board the model and should be protected from vibration, shock and temperature extremes. To protect the receiver, wrap it in R/C foam rubber or other vibration-absorbing material. If appropriate, waterproof the receiver by placing it in a plastic bag and closing the open end with a rubber band before wrapping it on chassis. If moisture enters the receiver, intermittent operation or a failure may result. Wrapping the receiver in a plastic bag also protects it from fuel and exhaust residue which, in some cars, can work its way into the body. . . TRANSMITTER ANTENNATRANSMITTER ANTENNA 1.

Statement of Declaration FCC ID：Y9XHPIRACING00001 Product：3CH 2.4GHz FHSS RADIO SYSTEM Model：TF-40 1. Output power and channel separation of a Hopping device in the operating mode： In the operating mode, device turn on the RF carrier, TX data with GFSK modulation, in this method, each bit of data in a byte is encoded with multiple bits using a Pseudo Noise code(PN code).In this way the transmitters and receivers must use the same PN code and channel to communicate, then turn off the RF carrier with the specification of Dwell time. The output power and the channel spacing is not change in the operating mode. 2. Frequency range of a Hopping device： Hereby we declare that the frequency range of this device is ：2407～2477MHz. 3. Example of a hopping sequence in operating mode： Example of an operating mode with 71 hopping sequences： 13,9,5,17,29,25,21,33,45,41,37,49,61,57,53,65,6,73,69,10,22,18,14,26,38,34,30, 42,54,50,46,58,70,66,62,74,15,11,7,19,8,12,16,20,75,24,28,72,31,71,68,23,67,27 ,32,64,35,63,32,60,52,59,36,40,55,51,39,48,56,43,47. 4.Dwell time in operating mode The dwell time in operating mode is independent from the TX data. The calculation for a period is as follows：Dwell time=time slot length *number of hopping channels. The time of occupancy in the specified 28.4 second period (71 channel *0.4s) is equal to 28.4*(# of pulse in 28.4s/28.4)*pulse width. Pulse width=9.4ms;#pulse in 28.4s=13; Time of occupancy=28.4* (13/28.4)* 9.4=122.2ms≤400ms 5. Channel Separation in operating mode The normal channel spacing of the Hopping system is 1MHz independent of the operating mode.
