It is recommended to set throttle channel to Neutral condition or brake condition. • Always operate your program setup mode after stopping motor’s power or engine and disconnecting drive battery. • Make sure whenever you start operating your transmitter, turn your transmitter on and then turn your receiver on. Whenever you stop your transmitter, turn your receiver off first and your transmitter. • Always disconnect the battery pack from the speed control when not in use to avoid short circuits and possible fire hazard. • Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short circuits, which can damage ESC. • Don‘t make any changes on the structure and design of your controller unless they are described in the manual. • Only those components and accessory parts which have been recommended by us may be used. Use only genuine and matching Graupner/SJ connectors and accessory parts. • Make sure whenever you start connecting and operating the controller, that your transmitter is switched on, and has the throttle set to position “STOP”. Binding & RF Range Test BIND Press and hold Bind button for 3 sec while your receiver is powered on and then LED indicator is off. Now press Bind button of your transmitter and then receiver’s LED indicator is off. RF RANGE TEST When BIND button is touched after the connection between transmitter and receiver, RF RANGE TEST is now activated. RF TEST is continued during 90 seconds and it is automatically deactivated. RF RANGE TEST is deactivated by touching BIND button during RF RANGE TEST mode. Please note that your model is not controllable if your model is far away from you during Test mode due to the short transmit distance.
