Warning9For Your Safety As Well As That Of Others Do not operate outdoors on rainy days, run through puddles of water or use when visibility is lim-ited.Should any type of moisture (water or snow) enter any component of the system, erratic operation and loss of control may occur. Do not operate in the following places.-Near other sites where other radio control activity may occur.-Near people or roads.-On any pond when passenger boats are present.-Near high tension power lines or communication broadcasting antennas.Interference could cause loss of control. Improper installation of your Radio Control System in your model could result in serious injury.Operation Precautions Do not operate this R/C system when you are tired, not feeling well or under the inﬂuence of alco-hol or drugs.Your judgment is impaired and could result in a dangerous situation that may cause serious injury to yourself as well as others. Do not touch the engine, motor, speed control or any part of the model that will generate heat while the model is operating or immediately after its use.These parts may be very hot and can cause serious burns. Always perform an operating range check prior to use.Problems with the radio control system as well as improper installation in a model could cause loss of control. (Simple range test method)Have a friend hold the model, or clamp it down or place it where the wheels or prop cannot come in contact with any ob-ject. Walk away and check to see if the servos follow the movement of the controls on the transmitter. Should you notice any abnormal operation, do not operate the model. Also check to be sure the model memory matches the model in use. Turning on the power switches. Always check the throttle trigger on the transmitter to be sure it is at the neutral position.1. Turn on the transmitter power switch.2. Turn on the receiver or speed control power switch. Turning off the power switches Always be sure the engine is not running or the motor is stopped.1. Turn off the receiver or speed control power switch.2. Then turn off the transmitter power switch.If the power switches are turned off in the opposite order, the model may unexpectedly run out of control and cause a very dangerous situation. When making adjustments to the model, do so with the engine not running or the motor discon-nected.You may unexpectedly lose control and create a dangerous situation. (Fail safe function) Before running (cruising), check the fail safe function.Check Method; Before starting the engine, check the fail safe function as follows:1) Turn on the transmitter and receiver power switches.2) Wait at least one minute, then turn off the transmitter power switch. (The transmitter automatically transfers the fail safe data to the receiver every minute.)3) Check if the fail safe function moves the servos to the preset position when reception fails.The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when recep-tion fails. However, if set to a dangerous position, it has the opposite effect. When the reverse function was used to change the operating direction of a servo, the fail safe function must be reset. Setting example: Throttle idle or brake position 4PX-Eng-03-Safety-P8-11.indd 9 2014/07/17 12:47:10

CautionWarning10For Your Safety As Well As That Of Others (Only when Ni-MH/Li-ion batteries are used)Battery Handling Precautions Never plug the charger into an outlet of other than the indicated voltage.Plugging the charger into the wrong outlet could result in an explosion or ﬁre. Never insert or remove the charger while your hands are wet.You may get an electric shock. Do not use the transmitter's battery, HT5F1700B or FT2F1700BV2 as the receiver's battery.Since the transmitter's battery has an overload protection circuit, the output power will be shut down when the high current load is applied. This may result in runaway or fatal crash. Do not use commercial AA size Ni-MH and Li-ion batteries.Quick charging may cause the battery contacts to overheat and damage the battery holder. Do not short circuit the battery terminals.A short circuit across the battery terminals may cause abnormal heating, ﬁre and burns. Do not drop the battery or expose it to strong shocks or vibrations.The battery may short circuit and overheat; electrolyte may leak out and cause burns or chemical damage. When the model is not being used, always remove or disconnect the battery.Leaving the battery connected could create a dangerous situation if someone accidentally turns on the receiver power switch. Loss of control could occur. Always check to be sure your batteries have been charged prior to operating the model.Should the battery go dead while the model is operating, loss of control will occur and create a very dangerous situation. To recharge the transmitter battery, use the special charger made for this purpose.Overcharging could cause the battery to overheat, leak or explode. This may lead to ﬁre, burns, loss of sight and many other types of injuries. Always keep the charger disconnected from the outlet while it is not in use.Do this to prevent accidents and to avoid overheating. When running (cruising), do not use the dry cell battery box at the transmitter.The accessory dry cell battery box is for performance checks. Do not use it for other than performance checks. The dry cell battery may be separated from the battery box contacts by shock and the power cut off. If the power is cut off while running (cruising), a collision may occur. The use of Futaba a genuine NiMH or LiFe battery pack is strongly recommended.Do not connect the charger when the battery is not connected.A load will be applied to the circuit and the transmitter may be damaged.4PX-Eng-03-Safety-P8-11.indd 10 2014/07/17 12:47:13

WarningWarningCaution11For Your Safety As Well As That Of OthersStorage and Disposal Precautions Do not leave the radio system or models within the reach of small children.A small child may accidentally operate the system. This could cause a dangerous situation and injuries. Ni-Cd batteries can be very dangerous when mishandled and cause chemical damage. Do not throw Ni-MH/LiFe batteries into a ﬁre. Do not expose batteries to extreme heat. Also do not disassemble or modify a battery pack.Overheating and breakage will cause the electrolyte to leak from the cells and cause skin burns, loss of sight, and other injuries.When the system will not be used for any length of time, store the system with HT5F1700B batteries in a discharged state. Be sure to recharge the batteries prior to the next time the system is used. If the batteries are repeatedly recharged in a slightly discharged state, the memory effect of the Ni-Cd battery may con-siderably reduce the capacity. A reduction in operating time will occur even when the batteries are charged for the recom-mended time. (After discharge to 1cell E.V.=1V)<Battery Electrolyte>The electrolyte in Ni-MH/Ni-Cd batteries is a strong alkali. Should you get even the smallest amount of the electrolyte in your eyes, DO NOT RUB. Wash immediately with water, and seek medical attention at once. The electrolyte can cause blindness. If electrolyte comes in contact with your skin or clothes, wash with water immediately. Do not store your R/C system in the following places.- Where it is extremely hot or cold.- Where the system will be exposed to direct sunlight.- Where the humidity is high.- Where vibration is prevalent.- Where dust is prevalent.- Where the system would be exposed to steam and condensation.Storing your R/C system under adverse conditions could cause deforma-tion and numerous problems with operation. If the system will not be used for a long period of time, re-move the batteries from the transmitter and model and store in a cool, dry place.If the batteries are left in the transmit-ter, electrolyte may leak and damage the transmitter. This applies to the model also. Remove the batteries from it also to prevent damage. Do not expose plastic parts to fuel, motor spray, waste oil or exhaust.The fuel, motor spray, waste oil and exhaust will penetrate and damage the plastic. Always use only genuine Futaba transmitters, receivers, servos, ESCs (electronic speed con-trols), Ni-MH/Ni-Cd/Li-ion batteries and other optional accessories.Futaba will not be responsible for problems caused by the use of other than Futaba genuine parts. Use the parts speci-ﬁed in the instruction manual and catalog.Other Precautions<Battery Recycling>A used battery is a valuable resource. Insulate the battery terminals and dispose of the battery by taking it to a battery recycling center. 4PX-Eng-03-Safety-P8-11.indd 11 2014/07/17 12:47:15

DISP ONRadio waves are not being transmittedPWR ONRadio waves are beingtransmitted16Before UsingPower & Display SwitchThe power switch and display switch are push switches.When the power switch (PWR) is held down, operation starts by transmitting radio waves. When the display switch is held down, the transmitter side data can be checked and set. When the power is turned off, if the power switch or display switch is held down, the power is turned off. If both switches are pressed simultaneously, the power is turned off quickly.Power Off Forgotten Alarm & Auto Power OffAt T4PX initialization, if steering wheel, throttle trigger, push switch, edit button, or other operation is not performed within 10 minutes, an audible alarm will sound and the message "Warning: Auto power off" will appear.If steering wheel, throttle trigger, push switch, edit button or other operation is performed, the alarm is reset. Also turn off the power when the transmitter is not in use. If the alarm is not reset, the auto power off function will automatically turn off the power after 5 minutes. If you do not want to use this alarm and the auto power off function, they can be disabled by system setting (p.148).Low Battery AlarmIf the transmitter battery voltage drops below the usable range, an audible alarm will sound and "Low battery" will be displayed. Since the usable range of LiFe and NiMH batteries and LiFe batteries is different, the power supply used must be set by system setting.
