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.
Do not short circuit the battery.
Do not solder or repair, deform, modify, or
disassemble the battery and/or battery charger.
Do not drop the battery into a re or bring it near
a re.
Do not charge and store the battery in direct
sunlight or other hot places.
