Receiver 92926 75 FM M h z #1#2#3 Steering Throttle AUX B/DSC Switch AA Dry Cell Battery Holder Mechanical Speed Controller #2 Electronic Speed Controller ESC TRANSMITTER BATTERY INSTALLATION RECEIVER AND SERVO CONNECTIONS Your MX-3S Computer R/C system receiver is NOT equipped with BEC circuitry. DO NOT use more than 6.0 volts to power the receiver. Anything higher than 6.0 volts will burn-up or destroy your receiver. Only use a 4.8~6.0 volt battery pack or a speed controller that is designed to lower the voltage to the receiver. The following diagram shows a typical connection for the servos and receiver. Note that the receiver antenna should be located at least 2โ (50mm) away from any servo leads and switches. In electric cars, we recommend that it be at least 4โ (100mm) from the electric motor. Extend the receiver antenna to the full length. Failure to do so will cause loss of control. Do not cut or bend the receiver antenna. Insulate the connectors with tape or use tie wraps to avoid contact with metal car chassis. Please follow the model manufacturers recommendations for the correct installation of your radio system in your car or boat. Switch To Battery To Motor ! CAUTION When installing your MX-3S radio system in your model, always make sure to set your model on a stand so the wheels are free from any traction before turning on your radio and or connecting your motor for the first time. TRIGGER POSITION ADJUSTMENT Throttle Trigger Set Screw Throttle Trigger Position Gauge A B Throttle Trigger Adjustment screw NOTE: Trigger Set Screw must be loosened before adjusting The Throttle Trigger can be adjusted to give you a more natural feel of the throttle. To Adjust: 1. Loosen the Throttle Trigger set screw by turning counter clock-wise. 2. Turning the adjustment screw clock-wise will move the trigger out or in the (A) direction. 3. Turning the adjustment screw counter clock-wise will move the trigger in or towards the (B) direction. 4. After adjustment is made, re-tighten the Trigger Set Screw. 5. Total adjustment for the trigger is 10mm. Do Not over tighten adjustment screw, it may damage the adjuster and or the threads. TROUBLESHOOTING GUIDE and WARNINGS If your radio system does not operate properly, please check the following items: 1. Make sure the batteries are properly installed and fully charged. Make certain all the batteries are installed in the correct direction. 2. Check that both the transmitter and receiver power switches are in the ON position. 3. Check the battery voltage by turning on the transmitter and pushing both menu bottons at the same time and releasing. 4. Make sure that the proper frequencies are set on both the transmitter and receiver. 5. Make sure all the receiver and servo connections are tight. WARNINGS: DO NOT OPERATE YOUR SYSTEM IF SOMEONE ELSE IS ON YOUR FREQUENCY AT THE SAME TIME. YOUR MODEL CAN CAUSE SERIOUS DAMAGE OR INJURY SO PLEASE USE CAUTION AND COURTESY AT ALL TIMES. DO NOT EXPOSE THE RADIO SYSTEM TO WATER OR EXCESSIVE MOISTURE. PLEASE WATERPROOF THE RECEIVER AND SERVOS BY PLACING THEM IN A WATER TIGHT RADIO BOX WHEN OPERATING R/C BOAT MODELS. IF YOU HAVE LITTLE OR NO EXPERIENCE OPERATING R/C MODELS, WE STRONGLY RECOMMEND YOU SEEK THE ASSISTANCE OF EXPERIENCED MODELERS OR YOUR LOCAL HOBBY SHOP FOR GUIDANCE.
