Tsauro-Z (600-4131) Troubleshooting Faxback Doc. # 6766 If the vehicle does not operate properly, check the following: Be sure all batteries are fresh and the battery pack is fully charged. Check for interference from other nearby radio-controlled devices. Interference can also come from overhead high-voltage wires and power transformers. Be sure the vehicle is not out of the transmitter's range. The range depends on the surrounding terrain and battery strength. If there are obstructions (building, fences, and so on) between the transmitter and the vehicle, the range is reduced. For maximum battery life, rest the vehicle for 20 minutes after every 15 minutes of continuous use. If the vehicle moves slowly or does not move at all, replace the vehicle's batteries or recharge the battery pack. If the motor runs but the vehicle does not respond to the transmitter, replace the transmitter's batteries. If the vehicle moves slowly and you have installed fresh batteries, check the wheel mechanisms for lint, thread, hair, or dust. If someone uses a CB nearby, it might interfere with control of the vehicle. If this happens, move the vehicle away from the CB. You cannot operate your vehicle near devices with transmitters of the same frequency. Do not store the vehicle or transmitter in direct sunlight or near a heater. Do not leave the vehicle or transmitter outside overnight. Night dampness can damage them. THE FCC WANTS YOU TO KNOW The vehicle and transmitter might cause TV or radio interference even when they are operating properly. To determine whether they are causing the interference, turn them off. If the interference goes away, the vehicle and transmitter are causing the interference. Try to eliminate the interference by: Moving the vehicle and transmitter away from the receiver. Contacting the local Radio Shack store for help. If you cannot eliminate the interference, the FCC requires that you stop using the vehicle and transmitter. FCC regulations forbid unauthorized modification of this product. If you or anyone else makes such modifications, you might lose the right to use the product. (CJD/all-8/18/94)
