Battery And Charger Handling Precautions - FUTABA T16SZ Instruction Manual

Do not fly 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 communi-
cation facilities.
When setting the transmitter on the ground
during flight preparations, do not stand it upright.
■ The transmitter may tip over, the sticks may move and
the propeller or rotor may rotate unexpectedly and
cause injury.
Do not touch the engine, motor, or ESC during
and immediately after use.
■ These items may become hot during use.
For safety, fly 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 al-
so 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 flying, always return the transmitter set-
up 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 fly-
ing session prior to flight.
■ Low battery capacity will cause loss of control and a
crash.

Battery and Charger Handling Precautions

DANGER
Do not recharge a battery that is damaged, de-
teriorated, 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, repair, deform, modify, or disas-
semble the battery and/or battery charger.
Do not drop the battery into a fire or bring it
near a fire.

Always check operation of each control surface
and perform a range test before each flying ses-
sion. Also, when using the trainer function, check
the operation of both the teacher and student
transmitter.
■ Even one incorrect transmitter setting or aircraft abnor-
mality 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 first and then the receiver.
When turning off the transmitter's power
switch after the engine or motor has stopped
(state in which it will not rotate again):
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 or-
der, the propeller may rotate unexpectedly and cause
a serious injury.
■ Also always observe the above order when setting the
fail safe function.
When adjusting the transmitter, stop the
engine except when necessary. In the case of a
motor, disconnect the wiring that allows it to con-
tinue operation. When doing so, please exercise
extreme caution. Ensure that the aircraft is se-
cured 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 charge and store the battery in direct
sunlight or other hot
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 envi-
ronment.
■ The combustibles may could ignite 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 battery with the dedicated charger
supplied with the set.
