Flying Precautions
WARNING
Never grasp the transmitter antenna while ying.
■ The transmitter output may drop drastically.
Always make sure that all transmitter stick
movements operate all servos properly in the model
prior to flight. Also, make sure that all switches,
etc. function properly as well. If there are any
difculties, do not use the system until all inputs are
functioning properly.
Never y in the range check mode.
■ In the dedicated range test range check mode, the
transmitter output range is reduced and may cause a
crash.
While operating, never touch the transmitter with,
or bring the transmitter near, another transmitter, a
cellphone, or other wireless devices.
■ Doing so may cause erroneous operation.
Do not point the antenna directly toward the
aircraft during ight.
■ The antenna is directional and the transmitter output
is weakest. (The strength of the radio waves is greatest
from the sides of the antenna.)
Never y on a rainy day, when the wind is strong,
and at night.
■ Water could lead to failure or improper functionality
and poor control of the aircraft which could lead to a
crash.
Never turn the power switch on and off during
ight or while the engine or motor is running.
■ Operation will become impossible and the aircraft will
crash. Even if the power switch is turned on, operation
will not begin until transmitter and receiver internal
processing is complete.
Do not y when you are physically impaired as it
could pose a safety hazard to yourself or others.
Do not touch the engine, motor, or FET amp
during and immediately after use.
■ These items may become hot during use.

<Introduction>
Battery and Charger Handling Precautions
DANGER
Do not charge the battery if it is covered with any
object as it may become very hot.
Do not use the battery in a combustible
environment.
■ The gas could ignite and cause an explosion or fire.
Always charge the battery before each flying
session.
■ If the battery goes dead during flight, the aircraft will
crash.
Charge the nickel-metal hydride battery with the
dedicated charger supplied with the set.
■ Charging the battery past the specified value may
cause a fire, combustion, rupture, or liquid leakage.
When quick charging, do not charge the battery above
1C.
■ Do not charge the battery while riding in a vehicle.
Vibration will prevent normal charging.
Do not y at the following places:
■ Near another radio control flying field.
■ Near or above people.
■ Near homes, schools, hospitals or other places where
people congregate.
■ Near high voltage lines, high structures, or
communication facilities.
For safety, y so that the aircraft is visible at all
times.
■ Flying behind buildings or other large structures
will not only cause you to lose sight of the aircraft, but
also degrade the RF link performance and cause loss of
control.
From the standpoint of safety, always set the fail
safe function.
■ In particular, normally set the throttle channel to idle.
For a helicopter, set the throttle channel to maintain a
hover.
When ying, always return the transmitter setup
screen to the Home screen.
■ Erroneous input during flight is extremely dangerous.
Always check the remaining capacity of the
transmitter and receiver batteries before each ying
session prior to ight.
■ Low battery capacity will cause loss of control and a
crash.
Always check operation of each control surface
and perform a range test before each ying session.
Also, when using the trainer function, check
the operation of both the teacher and student
transmitter.
■ Even one transmitter setting or aircraft abnormality
can cause a crash.
Before turning on the transmitter:
1. Always move the transmitter throttle stick position
to the minimum (idle) position.
2. Turn on the transmitter rst and then the receiver.
To turn off the transmitter's power switch, wait
until after the engine or motor has stopped (the state
in which it will not rotate again), and then:
1. Turn off the receiver power switch.
2. Then turn off the transmitter power switch.
■ If the power switch is turned on/off in the opposite
order, the propeller may rotate unexpectedly and cause
a serious injury.
■ Also always observe the above order when setting
the fail safe function.
■ Maximum low throttle: Direction in which the engine
or motor runs at the slowest speed or stops.
When adjusting the transmitter, stop the engine
except when necessary. In the case of a motor,
disconnect the wiring and to allow it to continue
operation. When doing so, please exercise extreme
caution. Ensure that the aircraft is secured and that
it will not come into contact with anything or anyone.
Ensure that the motor will not rotate prior to making
any adjustments.
■ Unexpected high speed rotation of the engine may
cause a serious injury.
Do not recharge a battery that is damaged,
deteriorated, leaking electrolyte, or wet.
Do not use the charger in applications other than
as intended.
Do not allow the charger or battery to become
wet.
■ Do not use the charger when it or your hands are
wet. Do not use the charger in humid places.

System Compatibility
Contents and Technical Specications
The 12K is a 2.4GHz T-FHSS Air system. The transmitter can also be switched to S-FHSS. (However, the telemetry
system cannot be used with S-FHSS.) The usable receivers are shown below.
NOTE：
*The Futaba T-FHSS Air system cannot be used with Futaba S-FHSS/FASST/FASSTest systems.
Use it with a T-FHSS Air system transmitter and receiver. The T12K is a T-FHSS Air system,
but can also be used with an S-FHSS receiver by switching to S-FHSS. However, in this case the
telemetry system cannot be used.
*The T-FHSS Air system and T-FHSS surface system are different. The T12K cannot be used with
the R304SB, R304SB-E or T-FHSS surface system receivers.

<Before Use>
As with all radio frequency transmissions,
the strongest area of signal transmission is from
the sides of the transmitter antenna. As such,
the antenna should not be pointed directly at the
model. If your ying style creates this situation,
easily move the antenna to correct this situation.
LED
• Off
Radio waves are in the OFF state.
• On
Radio waves are being transmitted.
• Blinking
Power switch is turned on when any
condition switch is activated (in the ON
state).
Monitor LED display
Transmitter status is displayed by LEDs.
Rotating antenna
The antenna can be rotated 180 degrees and
angled 90 degrees. Forcing the antenna further
than this can damage it. The antenna is not
removable.
Caution
Please do not grasp the transmitter
antenna during ight.
Doing so may degrade the quality of the RF
transmission to the model
Do not carry the transmitter by the
antenna.
This could damage the antenna and render the
transmitter inoperable.
Do not pull the antenna forcefully.
This could damage the antenna and render the
transmitter inoperable.
Low power
High power High power
Do not point the tip of the
antenna at a flying model,
this reduces signal quality.
If you want to point your
transmitter at a model, bend
the antenna 90 degrees for
best signal strength.
