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 danger-
ous 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.
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.

Ni-MH/Ni-Cd/LiFe Battery Handling Precautions
Warning
Never plug the charger into an outlet 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 T7PXR transmitter’s battery 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. As a result, runaway or fatal crashes can occur.
Always check to be sure your batteries have been charged prior to operating the model.
If the battery goes dead while the model is running, control is lost, and a very dangerous situation occurs.
To recharge the transmitter battery, use the special charger made for this purpose.
Overcharging could cause the battery to overheat, leak, or explode. As a result, it may lead to fire, burns, loss of sight, and many
other types of injuries
Caution
Do not use commercial AA size Ni-Cd and Ni-MH batteries.
Quick charging may cause the battery contacts to overheat and damage the battery holder.
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 batteries
will be separated from the battery box contacts by shock, and the power may be cut off. There is the danger of collision if the power
is cut while running (cruising). The use of Futaba genuine Ni-MH or LiFe batteries is strongly recommended.
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.
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.
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 keep the charger disconnected from the outlet while it is not in use.
Prevent accidents caused by abnormal heat generation etc.

Warning
Do not leave the radio system or models within reach of small children.
A small child may accidentally operate the system, and this could cause a dangerous situation and injuries. Ni-Cd batteries can be
hazardous when mishandled and cause chemical damage.
Do not throw Ni-MH/Ni-Cd/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 Ni-MH/Ni-Cd batteries in a
discharged state. Be sure to recharge the batteries before 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 con-
siderably 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)
When a LiFe battery pack will not be used for a long time, to prevent it from deteriorating we recommend
that it be kept in about the half capacity state instead of fully charged. Also, be careful that the battery
does not enter the over-discharged state due to self-discharge.
Periodically (about every three months) charge the battery.
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 mod-
el and store in a cool, dry place.
If the battery remains in the transmitter, the electrolyte may leak and damage the transmitter. This phenomenon also applies to
models. Also, remove the battery to prevent damage.
