2.4GHz System Precautions

Warning

Special attention should be paid before turning on the system while other cars are running or other airplanes are flying because the 2.4GHz RC system could potentially affect them.

Be sure to set the Fail Safe function.

High Speed Mode Precautions

Caution

When using the T4PL in the high speed (HIGH) mode, always use it under the following conditions:

Servos	:Futaba digital servo (including BLS Series brushless servos)
Receiver’s battery	:Matched to the ratings of the receiver and connected digital servo (dry cell battery cannot be used).
Transmitter mode	:HIGH mode (See p.42 for setting method.)

Under other conditions, the set will not operate, or the specified performance will not be displayed even if it operates. In addition, it may cause servo trouble. Futaba will not be responsible for damage, etc. caused by combination with the products of other companies.

In addition, the FSU Fail Safe Unit cannot be used because the system is different. Use the fail safe function of the transmitter.

When using analog servos, always switch the T4PL servo response to the "NORM" mode.

Transmitter mode :"NORM" mode (See p.42 for setting method.)

Receiver’s battery :Matched to the ratings of the receiver and connected servo (dry cell battery cannot be used).

The set cannot operate in the "HIGH" mode. Operation in this mode will cause trouble with the servo and other equipment. Digital servos (including BLS Series brushless servos) can also be used in the "NORM" mode.

Operation Precautions

Warning

Do not operate outdoors on rainy days, run through puddles of water or use when visibility is limited.

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.

Do not operate this R/C system 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 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 object. 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 disconnected.

You may unexpectedly lose control and create a dangerous situation.

For Your Safety As Well As That Of Others

Others Of That As Well As Safety Your For

Caution

(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 reception 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

NiMH / NiCd Battery Handling Precautions

(Only when NiMH/NiCd batteries are used)

Warning

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, 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.

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.

Caution

Do not use commercial AA size NiCd and NiMH 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.

10

Always keep the charger disconnected from the outlet while it is not in use.

Storage and Disposal Precautions

Warning

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 NiMH/NiCd 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-MH/Ni-Cd battery may considerably reduce the capacity . A reduction in operating time will occur even when the batteries are charged for the recommended time. (After discharge to 1cell E.V.=1V)

<NiMH/NiCd Battery Electrolyte>

The electrolyte in NiCd/NiMH 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

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 deformation and numerous problems with operation.

If the system will not be used for a long period of time, remove the batteries from the transmitter and model and store in a cool, dry place.

If the batteries are left in the transmitter, electrolyte may leak and damage the transmitter. This applies to the model also. Remove the batteries from it also to prevent damage.

<NiMH/NiCd/Li-ion 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.

Other Precautions

Caution

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 controls), NiMH/NiCd batteries and other optional accessories.

Futaba will not be responsible for problems caused by the use of other than genuine Futaba parts. Use the parts specified in the instruction manual and catalog.

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 to 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 another transmitter.

Link procedure

1 Bring the transmitter and the receiver close to each other, within 20 inches (half meter).

2 Turn on the transmitter.

3 Turn on the receiver.

4 Push the tactile switch of the receiver.

When the link is complete, the LED in the receiver changes to solid green.

Precaution:

If there are many Futaba S-FHSS/FHSS systems turned on in close proximity to the R2104GF, your receiver might not link to your transmitter. In this case, even if the receiver's LED stays solid green, unfortunately the receiver might have established a link to one of other transmitters. This is very dangerous if you do not notice this situation. In order to avoid the problem, we strongly recommend you to doublecheck whether your receiver is really under control by your transmitter by giving the stick input and then checking the servo response.

Before Using

*Please refer to the table below for LED status vs receiver's condition.

LED status vs receiver's condition:

No signal reception	Red : On
Receiving signals	Green: On
Receiving signals, but ID is unmatched.	Green: Blink *1

*1: LED could be change to red during intermittently during data processing.

Warning

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

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

Keep the antenna as far away from the motor, ESC and other
noise sources as you possibly can.
Wrap the receiver with something soft, such as foam rubber, to
avoid vibration. If there is a chance of getting wet, put the receiver		R2104GF
in a waterproof bag or balloon.

Caution

Always use R2104GF under the following conditions:

Battery :Power requirement Rated voltage 4.8~7.4V (dry cell battery cannot be used) / 3.5 to 8.4V useable

Matched to the ratings of the receiver and connected servo.

RX Type :"SFH" or "FH" (See p.42 for setting method.)

Transmitter mode-"HIGH" mode :Futaba digital servo (See p.42 for setting method.)

Transmitter mode-"NORM" mode :Futaba all servo (See p.42 for setting method.)

Under other conditions, the set will not operate, or the specified performance will not be displayed even if it operates. In addition, it may cause trouble with servos and other equipment. Futaba will not be responsible for damage, etc. caused by combination with the products of other companies.

Transmitter mode setting

Set the transmitter to the "HIGH" mode or "NORM" mode. See page 42 for a description of the setting method.

Note: However, digital servos (including BLS Series brushless servo) can only be used in the HIGH mode.

When the power is turned on, whether the receiver is in the "HIGH" or "NORM" mode the R2104GF operates in that mode until the power is turned off. When the transmitter mode is changed, operation becomes possible when the receiver power is turned on again.

Installation

Receiver and Servo Connections

Connect the receiver and servos as shown below. Connect and install the receiver and servos in accordance with "Installation Safety Precautions" on the next page.

The figure shown below is an example. The method of connecting the motor controller to the motor and battery depends on the motor controller used. Purchase the motor controller and servos separately. The receiver also depends on the set.

Installation Safety Precautions

Warning

Receiver (receiver antenna)

Do not cut or bundle the receiver antenna wire.

Do not bundle the receiver antenna wire together with the motor controller lead wire.

Keep the receiver antenna wire at least 1cm away from motor, battery, and other wiring carrying heavy current. Install the receiver antenna holder as closely as possible to the receiver.

If the antenna wire is cut, bundled, or routed near a noise source, the receiving sensitivity will drop, the running (sailing) range will decrease, and you may lose control of the model.

*Noise is transmitted through metal, carbon, and other conductive material, so keep the receiver antenna wire away from such parts.

Antenna

Battery	Install the receiver as far away as possible from the
	battery, motor controller, motor, silicon cord and
	other noise sources. Keep it away from the antenna
	wire, in particular.

Receiver vibration-proofing / waterproofing

(Car)

Vibration-proof the receiver by wrapping it in foam rubber or other vibration-absorbing material and mount it with thick double-sided tape.

When using the receiver holder supplied with the model kit, mount the holder to the chassis through a rubber grommet.

(Boat)

Vibration-proof the receiver by wrapping it in foam rubber or other vibration-absorbing material. Also waterproof the receiver by sealing it in a plastic bag.

If the receiver is exposed to strong vibration and shock, it will operate erroneously due to the invasion of water drops and you may lose control of the model.

Warning

Connector Connections

Be sure the receiver, servo, battery and connectors are fully and firmly connected.

If vibration from the model causes a connector to work loose while the model is in operation, you may lose control .

Servo Installation

When you install the servos, always use the rubber grommets provided in servo hardware bags. Mount the servos so they do not directly come in contact with the mount.

If the servo case comes in direct contact with the mount, vibration will be directly transmitted to the servo.

If this condition continues for a long time, the servo may be damaged and control will be lost.

Nut (as required)

When installing the servo, always install the accessory rubber grommet and grommet flush against the servo.

A vibration-damping effect is not obtained even if the rubber grommet and grommet are not installed correctly.

Servo Throw

Operate each servo over its full stroke and be sure the linkage does not bind or is loose.

The continuous application of unreasonable force to a servo may cause damage and excessive battery drain.

Adjust the steering servo so that unreasonable force is not applied to the servo by the chassis at maximum servo travel.

Adjust the throttle servo so that unreasonable force is not applied when the engine carburetor is fully open, fully closed, and the brakes are applied fully.

If the brakes overheat while running, their ability to function properly decreases. Before running, adjust the suitable maximum servo travel so that unreasonable force is not applied even when the servo travel is increased while running.

Warning

Electronic Speed Control

Install the heat sinks where they will not come in contact with aluminum, carbon fiber or other parts that conduct electricity.

If the FET Amp (Electronic speed control) heat sinks touch other materials that conduct electricity a short circuit could occur. This could result in loss of control and damage to the system.

Motor Noise Suppression

Always install capacitors to suppress noise when electric motors are used.

If capacitors are not properly installed you could experience erratic operation and reduced range as well as loss of control.

Motors with no suppressor capacitors, or inadequate suppression, may cause the receiver to malfunction. Always solder the capacitors supplied to your motor.

The Schottky diode improves the efficiency of the speed control / motor combination and provides extra protection to the brake FETs. The white ring must always face the positive side.

Schottky diode

Other Noise Suppression Methods

Be sure there are no metal parts in your model which under vibration can come in contact with other metal parts.

Metal to metal contacts under vibration will emit a high frequency noise that will affect the receiver's performance. You could experience erratic operation and reduced range as well as loss of control.

1.Rx Type Check

The T4PL transmitter can use both FHSS 2.4GHz system and increased response S- FHSS 2.4GHz system receivers. The R2104GF receiver supplied with the T4PL set can be used in both the FHSS type and S-FHSS type modes by automatic recognition. As the FHSS type mode cannot be used when the FHSS 2.4GHz system R603GF/R2004GF receiver is used, check the setting. If the setting is incorrect, change it using "RX MODE" (P42). Which RX type is set can be checked with the HOME screen.

"HIGH" is displayed for high speed type and nothing is displayed for normal type.

2. Servo Response Mode Check

When the RX type is set to S-FHSS 2.4GHz (SFH), the servo response mode can be set to the high speed mode (HIGH). However, check if the servos used are compatible. When using digital servos (including BLS Series

brushless servos), either "HIGH" or "NORM" can

be used. Since "HIGH" cannot be used with other analog servos, the servo response mode must be

set to "NORM". If the setting is incorrect, change it using "RX MODE" (P42). When the RX type is set to FHSS 2.4GHz (FH) the high speed mode cannot be selected
