 WARNING

 Do not cover/hold the built-in antenna part of T2PSK-2.4G transmitter by your hand during running. Do not put any conductive plate/sticker on the antenna part. Otherwise, the operating range may become shorter.

 Do not perform the linking procedure while motor's main wire is connected or the engine is operating as it may result in serious injury.

 While the linking is done, please cycle receiver power and check if the receiver to be linked is really under the control by the transmitter to be linked.

 Always use R202GF 4.8V~7.4V rechargeable battery or regulated output from ESC. Using dry cell batteries may cause the system to malfunction. When using an ESC, be sure that the regulated output capacity meets your usage condi-

tion.

 In order to maintain complete control of your car/boat it is important that it remains visible at all times. Running behind large objects is not suggested. Doing so may result in the reduction of the quality of the radio frequency link to the model. 4 Safety Precautions Operation Precautions

 WARNING

 When using a Ni-Cd/Ni-MH battery to power your system, always charge and check the battery voltage prior to operation. Should the battery discharge below the minimum voltage level, control will be lost.

 Prior to operation always perform a range test. Even one abnormality in the R/C system may cause loss of control.

[Range Test Procedure]

Have a friend hold the model, or place on a stand where the wheels or prop can not come in contact with any object. Operate from a distance of about 100 feet. Be sure to check the movement of each servo to make sure it follows the movement of the steering wheel and throttle trigger. If the servos do not follow the commands from the transmitter or any type of interference is detected, Do Not operate the model.

 Never operate in the rain or run through puddles. The transmitter, receiver, batteries and most servos, and speed controls are not water-

proof. Contact with any type of moisture or immersion in water or snow will cause damage along with possible loss of control. Should any type of moisture enter any component of the system, immediately stop using the R/C system and return it to our service center for inspection.

 Do not operate when visibility is limited. Should you lose sight of the model, a collision or other dangerous situation may occur.

 Do not operate near people or roads. Do not operate on any pond when boats are present. Do not operate near high tension power lines or communication broadcasting antennas. Prior to the operation of any model be sure the area you plan to use is safe. Be aware of all objects that may be in the path of your model. Do not operate the model where people or any type of moveable object could stray in the path of your model. Control loss due to inter-

ference, component failure, loss of sight or low battery voltage could result in serious injury to yourself and others as well as damage to your model.

 Do not operate when you are tired, not feeling well or under the influence of alcohol or drugs. Your judgment is impaired and could result in a dangerous situation that may cause serious injury to yourself and others.

 (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. Safety Precautions 5

 Make all adjustments to the radio control system with engine not running, or the electric motor disconnected. If the engine is running or the motor is connected while adjustments are made, the model may run out of control.

 Remove the main battery source from electric powered models when they are not being used. Should you accidentally leave the receiver switch on, the model could run out of control.

 (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. Turn off the transmitter power switch. 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 reception fails. However, if set to a dangerous position, it has the opposite effect. Setting example: Throttle idle or brake position

 CAUTION

 Do not touch the engine, motor, speed control or any part of the model that will generate heat while running. Touching hot parts will result in serious burns.

 When the charger is not in use, disconnect it from the outlet. This will prevent accidents, overheating and short circuits. Storage and Disposal Safety Precautions

 WARNING

 At the end of a day's operation, store the system with Ni-Cd/Ni-MH battery discharged. Be sure to recharge the system before it is used again. You should fully discharge your system's batteries periodically to prevent a condition called

"memory". For example, if you only make two runs in a day or you regularly use a small amount of battery's capacity, the memory effect can reduce the actual capacity even if the battery is charged for the recommended amount of time.

 Do not throw a Ni-Cd/Ni-MH battery into a fire. Do not disassemble or attempt to repair a Ni-Cd/Ni-MH battery pack. Overheating, damage and acid leakage may lead to burns, loss of eye sight as well as nu-

merous other types of injuries. The electrolyte in Ni-Cd/Ni-MH 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 immedi-

ately. 6 Safety 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/

Ni-MH batteries can be very dangerous when mishandled and cause chemical damage.

 CAUTION

 Do not store your R/C system where it will be exposed to the following conditions. Extreme heat or coldness Exposed to direct sunlight Where humidity is high Where vibration is prevalent Where dust is prevalent Where there is steam and condensation Storing your R/C system under adverse conditions could cause deformation and numerous other problems with operation.

 If the system will not be used for a long period of time, remove the batteries from the model and store in a cool, dry place. If the batteries are left in the model, electrolyte may leak and damage the model.

<Ni-Cd/Ni-MH Battery Recycling>

A used Ni-Cd/Ni-MH battery is valuable resource. Insulate the battery terminals and dispose of the battery by taking it to a battery recycling center. Other Safety Precautions

 CAUTION

 When operating two or more models at the same time, have a third person act as a spotter. They will be in charge of safety and you should follow their instructions.

 Beginners should receive instructions regarding safety and operation from an experienced modeler.

 Always use only genuine Futaba transmitter, receivers, servos, and electronic speed controls, along with other optional parts and components. Futaba will not be held responsible for damages caused by other than genuine Futaba parts and components. Use only genuine Futaba parts and components listed in the in-

struction manual and catalog.

 Do not short circuit the Ni-Cd/Ni-MH battery terminals. Short circuiting the terminals will lead to sparks and overheating and could cause a fire and burns as well. The fuel, motor spray, waste oil and exhaust will penetrate and damage the plastic.

 Do not expose plastic parts to fuel, motor spray, waste oil or exhaust.

<Ni-Cd/Ni-MH Battery Electrolyte>

The electrolyte in Ni-Cd/Ni-MH 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.

 WARNING

 Install the antenna in the higher place as shown in the figure. Keep the antenna as far away from the motor, ESC and other noise sources as possible. Put the antenna in the antenna tube to protect it.

 Do not cut the antenna. Do not bend the coaxial cable. Doing so causes damage. Antenna tube Antenna Coaxial cable R202GF 12 Assembly / Adjustment Assembly Precautions

 WARNING

 Check the receiver, servos, and battery connectors, to be sure they are firmly connected. If a connector is not fully inserted, vibration may cause the connector to work loose while the model is operating. This will result in loss of control.

 Operate each servo horn over its full stroke and check to see that the linkage does not bind or is not too loose. Excessive force applied to the servo horn by binding or poor installation may lead to servo problems and result in loss of control.

 (Electric Cars and Boats) Isolate the receiver from vibration by attaching to the chassis or mounting plate with thick double sided tape.

(Gas Powered Cars and Boats) Isolate the receiver from vibration by wrapping it in foam rubber or similar type cushioning material. Protect the unit from water damage by placing it in a plastic bag or waterproof ra-

dio box. The receiver contains precision electronic parts. These parts are vulnerable to vibration and shock. Any contact with moisture (water or condensation) may cause receiver malfunction and loss of control.

 Use the servo horn screw. When the servo horn comes off, it becomes loss of control.

 Keep all devices that emit high frequency noise, such as motors, batteries, and wiring that handles heavy current loads, at least 1/2 inch away from the receiver and the receiver antenna. High frequency noise will cause a decrease in operating range and could cause loss of control.

 Install electronic speed control heat sinks as well as other components that conduct electricity so they can not come in contact with aluminum, carbon fiber or other materials that conduct electricity. If, for example, the speed control came loose while the model was running and touched an aluminum chassis, a short circuit may occur that would cause irreparable damage to the system as well as loss of control.

 Noise suppression capacitors should be installed on almost all motors. If the proper capacitors are not installed, high frequency noise will reduce range and cause loss of control along with various other problems.

 Inspect all linkage installations and any point where metal could come in contact with other metal parts. Make sure these parts do not touch other metal parts under vibration. Should a linkage or other metal parts come in contact with other metal parts under vibra-

tion, the high frequency noise generated by this contact will cause interference and pos-

sible loss of control.

 CAUTION

 Do Not disassemble any part of this system that is not specified in the instruction manual. Futaba will not be responsible for any damage due to improper disassembly of any part of the radio control system. Assembly / Adjustment 13 How to link the transmitter and the receiver Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with the ID code of the transmitter with which it is being paired. Once the link is made, the ID code is stored in the receiver and no further linking is necessary unless the receiver needs to be used with an other transmitter. (For T/R set, the link is already done at factory.)

PROTECTION CIRCUIT OPERATION The following protection circuits are built into the MC231CR / MC331CR. When a protection circuit operates, remove the cause before operating the model again. Overcurrent protection Heat protector Low voltage operation When an overcurrent flows due to an output short circuit, etc., the overcurrent protection circuit automatically limits the current to protect the FET. Remove the cause of the short circuit, etc. before operating the model again. When abnormal heating of the FET due to an overload, etc. is detected, the heat protector operates so that the speed is gradually reduced. When the FET temperature drops, the heat protector automatically resets. However, remove the cause of the overheating before operating the model again. When the Nicd battery voltage drops, this function limits the motor output current and ensures steering operation. After the speed drops, immediately recover the vehicle.
