INFLATABLE RC SUMO INSTRUCTION Movement: Rule: ForwardForward LeftForward Right Spinning or Backward Note: Use on different surfaces may effect the units performance. Blue Sumo Blue controller Red controller Base Inflatable Part Inflatable Part NOTE: These two pieces Sumo somtimes “POP OFF it’s base. It will easily POP Back ON. Red Sumo Battery installation: EastWest Dohyo Do not mix old and new batteries. Do not mix alkaline, standard (carbon zinc) or rechargeable (nickel-cadmium) batteries. Rechargeable batteries are not recommended. Due to small parts, batteries should be replaced by adult. Batteries must be inserted with correct polarity. Non-rechargeable batteries cannot be recharged. Only batteries of the same or equivalent type as recommended can be used. Exhausted batteries must be removed from the toy. The supply terminals must not be short-circuited. For best results use alkaline batteries. IMPORTANT BATTERY INFORMATION: WARNING : Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. A bout is won by forcing the opponent out of the inner circle or by throwing him in the DOHYO. To lose the match it is not necessary to fall in the circle or to be pushed completely out. The rikishi who touches the ground with any part of his body, his knee or even the tip of his finger or his top-knot, loses the match. Or he need only put one toe or his heel over the straw bales marking the circle. The toeing-the-mark ritual that precedes the start of every bout in sumo.

Do not use vehicle in mud, water, snow, or sand. 2.Do not play with vehicle in the street. 3.Do not crash vehicle into any object at high speeds 4.When the vehicle slows down install new or freshly charged batteries. 5. Clean the vehicle with a damp paper towelafter operating.( Do not use any chemicals to wipe off car. 6.Do not leave vehicle in direct sunlight for lengthy periods. 7.Radio interfernce can cause your car to react strangely. 8.Another vehicle operating on the same frequency can disrupt your controlling the vehicle. 9.CB’s cellular telephones, two way radios, and other transmitting devices, and high tension wires may cause with operation. 10. Your vehicle can sometimes cause interference with television or even radio reception. Move to another area if you notice this occurrence. 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.

Operational Description

RC SUMO TX / RX Block Diagram Description 1) TX High frequency oscillation produces 27.145 MHZ OR 49.860 MHZ high frequency carrier wave. Then the carrier wave will mix with the numerical pulse and is amplified. Finally, the amplitude modulation carrier wave is transmitted though the TX antenna. At the same time, the speaker gives off sound. 2) RX Receive the 27.145 MHZ OR 49.860 MHZ amplitude modulation wave though the RX antenna. Then a carrier wave with same frequency is produced and detects the numerical pulse code. The IC will decode the numerical pulse code and transform to high radio frequency to drive the motor.
