8

Operation Precautions

Warning

ｎ

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

ｌ

Should any type of moisture (water or snow) enter any component of the system, erratic opreation and loss of control
may occur.

Do not operate in the following places.

ｌ

-Near other sites where other radio control activity may occur.

-Near people or roads.

-On any pond when row 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

ｌ

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.

Extend the transmitter antenna to its full length.

ｊ

If the transmitter antenna is not fully extended, the operating range of the radio will be reduced.

Always perform a operating range check prior to use.

ｊ

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.

For Your Safety As Well As That Of Others

Check the transmitter antenna to be sure it is not loose.

ｊ

If the transmitter antenna works loose, or is disconnected while the model is running, signal transmission will be lost.
This will cause you to lose control of the model. Rotate the antenna softly with your fingers when checking whether it is
loosely or firmly fixed. Do not screw the antenna forcibly. Otherwise its antenna-holding part can be damaged.

ｎ

Caution

Do not touch the engine, motor, speed control or any part of the model that will generate heat

ｌ

while the model is operating or immediately after its use.

These parts may be very hot and can cause serious burns.

Turning on the power switches.

ｊ

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.

9

For Your Safety As Well As That Of Others

When making adjustments to the model, do so with the engine not running or the motor discon-

ｊ

nected.

You may unexpectedly lose control and create a dangerous situation.

(Fail safe function)

Before running (cruising), check the fail safe function.

ｊ

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

Ni-MH / Ni-Cd Battery Handling Precautions

(Only when Ni-MH/Ni-Cd batteries are used)

Warning

ｎ

Never plug the charger into an outlet other than indicated voltage.

ｌ

Plugging the charger into the wrong outlet may result in an explosion, sparking, or fire.

Never insert or remove the charger while your hands are wet.

ｌ

You may get an electric shock.

Do not use the transmitter's battery, HT5F1700B, as the receiver's battery.

ｌ

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 run-a-way or fatal crash.

Always check to be sure your batteries have been charged prior to operating the model.

ｊ

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.

ｊ

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.

ｎ

Caution

Do not use commercial AA size Ni-Cd and Ni-MH batteries.

ｌ

Quick charging may cause the battery contacts to overheat and damage the battery holder.

Do not short circuit the battery terminals.

ｌ

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.

ｌ

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.

ｊ

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.

ｊ

Storage and Disposal Precautions

Warning

ｎ

Do not leave the radio system or models within the reach of small children.

ｌ

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/Mi-Cd batteries into a fire. Do not expose batteries to extreme heat. Also do

ｌ

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 batter-

ｊ

ies 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
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)

<Ni-MH/Ni-Cd 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.

Warning

ｎ

Do not store your R/C system in the following places.

ｌ

- 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

ｊ

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.

<Ni-MH/Ni-Cd Battery Recycling>

A used battery is valuable resource. Insulate the battery terminals and dispose of the battery by taking it to a battery recycling center.

Other Precautions

ｎ

Caution

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

ｌ

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-

ｊ

trols), Ni-MH/Ni-Cd 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 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

2

Turn on the transmitter.

3

Turn on the receiver.

Before Using

4

Push the tactile switch of the receiver.

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

Precaution:

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.

Warning

ｎ

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.
