RECEIVER AND SERVO CONNECTIONS
Your MX-3 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 2 (50mm) away from any servo leads and switches. In electric cars, we recommend that it be at least 4 (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 manufactures recommendations for the correct installation of your radio system in your car or boat.
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. With alkaline batteries, make certain 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 frequency crystals are installed in 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 FREQUENCE 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 WATER PROOF 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.
