(Only when NiMH/NiCd batteries are used)
NiMH / NiCd Battery Handling Precautions
ｌNever 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.
ｌNever insert or remove the charger while your hands are wet.
You may get an electric shock.
ｌDo 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 cur-
rent load is applied. This may result in runaway or fatal crash.
ｌDo not use commercial AA size NiCd and NiMH batteries.
Quick charging may cause the battery contacts to overheat and damage the battery holder.
ｌDo not short circuit the battery terminals.
A short circuit across the battery terminals may cause abnormal heating, fire and burns.
ｌDo 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.
ｊWhen 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.
(Fail safe function)
ｊBefore 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
ｊAlways 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.
ｊTo 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.

Storage and Disposal Precautions
ｌDo 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.
ｌDo 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.
ｊ
When the system will not be used for any length of time, store the system with HT5F1700B batter-
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-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.
ｌDo 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.
ｊIf 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 trans-
mitter, electrolyte may leak and dam-
age the transmitter. This applies to
the model also. Remove the batteries
from it also to prevent damage.
ｌDo 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.
ｊAlways use only genuine Futaba transmitters, receivers, servos, ESCs (electronic speed con-
trols), 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 speci-
fied in the instruction manual and catalog.
Other Precautions
<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.
ｊAlways keep the charger disconnected from the outlet while it is not in use.

Before Using
-2.4GHzSS (Spread Spectrum) radio communication system
Frequency channel setting is unnecessary: Channel shifting takes place within the 2.4GHz
band automatically. This system minimizes the interference from other 2.4GHz systems.
-Model memory for 40 models
Model names can use up to 10 letters, numbers, and symbols, so that logical names may be
used. A model memory with different setups can be created by using the model copy func-
tion.
- Menu Selection
The setup screens are called from menu screens. The menu screen can be selected from
among 2 levels (LEVEL1/LEVEL2).
-Brake mixing for large cars (BRAKE)
Brake mixing of the front and rear wheels of 1/5GP and other large cars can be adjusted
independently.
-4WS Mixes (4WS MIX)
This function can be used with crawlers and other 4WS type vehicles.
-Anti-skid braking system (A.B.S)
This function applies the brakes so that the tires of gasoline engine cars, etc. do not lose
their grip on the road even when braking at corners.
-Throttle acceleration (ACCFW/ACCBK)
Gasoline engine cars have a time lag before the clutch and brakes become effective.
The throttle acceleration function reduces this time lag.
-Throttle speed (SPEED)
Sudden trigger operation on a slippery road surface will only cause the tires to spin and the
model to not accelerate smoothly. By setting the throttle speed function, operation can be
performed smoothly and easily. It also suppresses battery consumption.
-Steering speed (SPEED)
When you sense that the steering servo is too fast, etc., the servo operating speed (direction
that suppresses the maximum speed) can be adjusted.
