Utilizing digital spectrum technology within the 2.4 GHz ISM band, the Radiopost RF System provides secure radio link, high transmission speed and superb resolution allowing the device to respond quickly and accurately without interference. The Radiopost Tx 2.4GHz Radio Control and receivers offer a significant advantage of eliminating the possibility of interference. Each Tx 2.4GHz Radio Control is programmed with a unique identification code to communicate with its specified receiver. Once the receiver is paired with the Tx 2.4GHz Radio Control (called ID Setting), the receiver will only take data from this specific radio controller where the Tx 2.4GHz Radio Control is equipped, ignoring signals from other sources. The Radiopost Tx 2.4GHz Radio Control and receivers scan and select the superior channels that are not being used to avoid collision in channels and data loss between the Tx 2.4GHz Radio Control and the receiver. This device complies with part 15 of the FCC rules. 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. FCC Information &OHMJTI ڍڋ Precautions Read this manual before installation or use. Do not disassemble the Tx 2.4GHz Radio Control and the receiver because it may cause severe damage or problems. Install the Tx 2.4GHz Radio Control and the receiver after cutting off the power of the radio controller and RC models such as model aircrafts or helicopters or cars. The receiver should be turned on after the radio controller is switched on. When turning on the radio controller, be sure to put the throttle to the stop position. When switching off, make sure the engine or the motor of the RC models should be stopped. First, switch off the receiver thenthe radio controller. If this is not done in this order, it may cause temporary malfunctions. Prior to actual use and control of RC models, perform operation tests between the Tx 2.4GHz Radio Control and the receiver. If these tests fail, do not operate RC models. When installing the receiver in RC models, use impact protection materials to avoid damage to the receiver, which may be caused by the vibration of RC models or the impact from the outside. Do not alter length of antenna arbitrarily. The antenna should not be hidden by the RC model's main body or cover, coated with metallic paint or carbon fiber. Do not use Radiopost Tx 2.4GHz Radio Control and receivers together with Tx 2.4GHz Radio Control and receivers produced by other manufacturers. Do not operate the Tx module with two or more receivers. The receiver antenna shall be installed not to get affected by the magnetic field of power cables. * Nextlink will not be responsible for damage caused by use which is prohibited. 4BGFUZ $BVUJPO &OHMJTI ڎڋ Name of Each Part RP24TD9JRP24TD9 ID Setting Button ID Setting Button Status LED Status LED ID Setting Button Status LED RP24TD9M RP24RA4DRP24RA8DRP24RA9DRP24RA6DRP24RA5D [For JR radio controllers] [For Sanwa radio controllers] [For Futaba and Hitec radio controllers] www.rcenjoy.com Spread Spectrum 2.4GHz2.4GHz RF MODULE www.rcenjoy.com ID SETSTATUS RP24TD9J 2.4GHz2.4GHz RF MODULE ID SETSTATUS RP24TD9RP24TD9 www.rcenjoy.com AntennaAntenna Antenna Status LED ID Setting Button RP24RA6DRP24RA6D 2.4GHz2.4GHz 6CH Receiver ID SET ՙ՞Շՙ՞Ոՙ՞Չՙ՞Պՙ՞Ջ ՘Յՙ՞Ռ www.rcenjoy.com Antenna Antenna Status LED ID Setting Button Failsafe Button RP24RA8DRP24RA8D 2.4GHz2.4GHz 8CH Receiver I D S E T F / S ՙ՞Շՙ՞Ոՙ՞Չ ՙ՞Պ ՙ՞Ջՙ՞Ռՙ՞Ս ՘Յՙ՞Վ www.rcenjoy.com Antenna Status LED ID Setting Button Failsafe Button Status LED ID Setting Button ՙՇ ՙՈՙՉՙՊ ՘ՅՙՋ 55 C h a n n e l R e c e i v e r www.rcenjoy.com 2.4GHz2.4GHz RP24RA5DRP24RA5D Antenna Status LED ID Setting Button Antenna ID SET 2.4GHz2.4GHz RP24RA4DRP24RA4D 44 ChannelChannel Tx 2.4GHz Radio Control Receiver &OHMJTI ڏڋ Tx Module Features High stability is guaranteed by using 2.4 GHz ISM bandwidth. Crystal is not necessary due to automatic channel selection. ID Setting is checked by beeping sounds. Binding speed is superior. The embedded Tx 2.4GHz Radio Control antenna provides convenience for users when the stand is attached to the radio controller. Radiopost Tx 2.4GHz Radio Control can be paired with any Radiopost receivers. It provides a wide range and high durability. It is a highly sensitive receiver which is less affected by intermodulation It is a universal type which can be used for model aircrafts,helicopters and cars.

Applicant Address : 701, Jungang Induspia II #144-5 Sangdaewon-dong, Jungwon-gu Seongnam-si, Gyeonhgi-do Kind of Product : 2.4GHz Radio Control Equipment model name : RP24TD9M Antenna type : Patch antenna Gain: 4.48dBi Frequency Range : 2405 ~ 2480 MHz Number of channels : 76 Channel Spacing : 1 MHz www.kes.co.kr Page 2 of 2 ** MPE Calculations ** The EUT will only be used with a separation of 20 centimeters or greater between the antenna and the body of the user. The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G EIRP = 13.93 dBm Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log -1 (4.48/ 10) G = 2.81 Power density at the specific separation: S = PG/(4R 2 π) S = (8.81 * 2.81 / (4 * 20 2 * π) S = 0.0049 mW/cm 2 Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) The Maximum permissible exposure (MPE) for the general population is 1 mW/cm 2 . The power density at 20cm does not exceed the 1 mW/cm 2 limit. Estimated safe separation: R = √(PG / 4π) R = √(8.81 * 2.81/ 4π) R = 1.40 cm Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE)
