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 Installation RR 3 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: 75~125% of each direction. Use the small Philip screwdriver (+) to turn the two small knobs inside the control panel upper side 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: 75~125% of each direction. Use the small Philip screwdriver (+) to turn the two 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 / EPA RR 4 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 Antenna 1. The transmitter antenna is adjustable so please make sure the antenna is never pointed directly at the model when running it as this creates a weak signal for the receiver. 2. Keep the antenna vertical to the ground to create a better RF condition for the receiver. Of course this depends on how you hold the transmitter, but in most cases, adjusting the transmitter antenna so that it is vertical to the ground will give the best results. 3. Never grip the antenna when using this transmitter as this degrades RF quality. 0 9 0 . . Receiving signals and ID is matched. : On Receiving signals, but ID is not matched. : Off No signal reception.: Off Receiver ID memory is empty.: Blink per second The transmitter has an individual randomize ID that is created in the factory; even it is almost have no chance to meet the same ID transmitter in the same fly field, in case it does happen. The transmitter has an ID set up function. By holding the “PDM” button to turn on the transmitter, the LED will blink. Press the “PDM” button to random change a new ID, the new ID will active when the transmitter turns on next time. Once you have set up a new ID for your transmitter, please must remember to re-pair your receiver with your transmitter before running. You can go back to the original factory set ID by holding the “PDM” when turn on the transmitter, without press the “PDM” button, turn it off and on again to get back the original factory set up ID. . . . . . . . . Chang the transmitter ID A range check must be performed before the first run of a new car. It is not necessary to do a range check before every run (but is not a bad idea to perform a range check before the first run of each day). A range check is the final opportunity to reveal any radio malfunctions, and to be certain the system has adequate operational range. . . . . Range check the radio RR 5 Pair Procedure The transmitter has an individual randomize ID that is created in the factory, In order to start operation, the receiver must be linked with the ID code of the transmitter with wh…
