With the nature of radio controlled models, misoperation will result in danger. In order to avoid these cir-
cumstances and to use this unit safely, please read the following safety precautions thoroughly.
Explanation of warnings and signs
Failure to observe the matter discussed in such an item poses a serious
threat of death or severe injury.
Failure to observe the matter discussed in such an item poses a possibility of death
or severe injury, and a great likelihood of damage to the equipment or property.
Failure to observe the matter discussed in such an item poses a possibility
of injury or damage to the equipment or property.
Meaning of picture indications
Prohibited matters
Not allowed to do.
Enforcement matters
Must carry out!
Notes in assembly of mechanism before use
Warning!
For replacement type crystals, be certain
to use only KO Propo genuine crystal sets
(transmitter and receiver).
Other crystals may vary in frequency or cause
reduction of output, which could lead to loss of
control.
Prevent metal or carbon parts from touch-
ing the body of the model (car or boat) due
to vibration.
Noise may be generated to deteriorate the receiv-
ing performance, which could lead to malfunction
or loss of control.
This product is only designed for ground
surface or water surface radio control mod-
els. Do not use for any other purposes.
If a nicad battery pack is used in the trans-
mitter or the receiver, be sure to use the
genuine products. Charge the batteries
properly before use.
If batteries are exhausted during traveling, the
model may run out of control.
Be sure to insert the connectors of receiver,
servo, switch, and so on securely.
If a connector is removed because of vibration in
traveling, the model may run out of control.
Be sure to secure a receiver with thicker
double-sided tape to prevent direct transfer
of vibration.
Vibration may cause damage to internal parts.
Do not cut or bundle the aerial wire of receiver.
It may result in decreasing the sensitivity of a re-
ceiver and may result in the model running out of
control.
After installing a servo, check the operation
and ensure that no undue force is applied.
Undue force may cause a servo failure or voltage
drop, which could lead to loss of control.
Be sure to use rubber grommets for mounting
a servo. Also prevent the servo from touching
any chassis directly.
Direct transfer of vibration to the servo may cause
a failure, resulting in the model running out of con-
trol.
Danger!
Warning!
Caution!
SAFETY PRECAUTIONS

ö
Before turning on the power switch of the
transmitter, ensure that the frequency band
is available.
Models using the same frequency may run out of
control.
Do not run the model when there is lightning.
There is a possibility of lightning striking the an-
tenna.
Do not run the model in the rain or in a location
where there is a puddle.
The unit may become wet, which could lead to
loss of control.
Do not run the model in the following places.
• Near to other radio control car circuits
(within 3 km)
• Near to people or on the road
• Surface of water where there are actual
boats
A model running out of control because of radio
interference or trouble is very dangerous.
Do not run the model when you experience
difficulties in concentration due to tiredness,
alcohol or medication.
Misjudgment may result in accidents.
Check for looseness of the antenna of the
transmitter and extend it to full length.
Incorrect emission of radio wave may cause the
model to run out of control.
Do not allow any plastic parts to come in
contact with fuel and exhaust of engine.
Fuel and exhaust affect the plastic and may dam-
age it.
Be sure to confirm that the model memory
matches the models currently running.
Not doing so may cause the model to run out of
control.
When you make functional changes, be sure
to stop the engine (disconnect the motor
lead wire).
Caution!
Be careful not to reverse the polarity of bat-
tery of the transmitter and the receiver.
Reverse polarity could damage the unit.
Be sure to use genuine KO Propo products
when combining transmitter, receiver, servo,
ESC and other optional parts.
We cannot assume any responsibility for use of
other companies' products with this unit.
Notes on driving (sailing)
Warning!
Caution!
Always turn on the switch on the transmitter
first, followed by the receiver. When turning
off the switch, always turn off the receiver
first, followed by the transmitter.
If you do not follow the correct order, the receiver
may get interference, which could lead to loss of
control.
Be sure to attach a band plate.
Display your frequency clearly to other people.
After traveling, do not touch the engine, mo-
tor or ESC where heat is generated.
Doing so may result in a burn.
Do not touch the antenna of transmitter.
Since the transmitter emits high-frequency energy
from the antenna, if you touch the antenna, you
may be shocked.

öé
Notes after driving (sailing)
Warning!
In the case of an electric-powered car, be
sure to disconnect the nicad battery after
completing driving.
A fire may occur or the model may run out of con-
trol if the switch is turned on by mistake.
When storing the transmitter, batteries, and
models, be sure to keep them out of the reach
of children.
Damage and/or injury from the chemicals may oc-
cur.
Be sure to disconnect the battery from the
transmitter when not using the transmitter
for a long time.
The transmitter may be damaged because of liq-
uid leaking if you leave the battery in the transmit-
ter for a long time.
Caution!
Do not store the transmitter or the receiver
in the following places.
• Extremely hot or cold places (+40 degrees
or higher, –10 degrees or lower)
• Places exposed to direct sunshine
• Places with high humidity
• Places with much vibration
• Dusty places
Storing the unit under these circumstances may
result in deformation of the case or a failure of the
unit.
Notes on handling and charging nicad battery (sold separately)
Danger!
Never short-circuit the battery terminals.
It is dangerous because it may cause the outbreak
of fire or explosion.
Do not incinerate the batteries.
It is very dangerous because they may explode.
Be sure to use a KO Propo charger for charg-
ing and to use correct charging current (1A or
less).
Incorrect charging current may cause explosion of
battery, excessive heat build-up and liquid leaking.
If other company's chargers are used, there is a
possibility that the auto cut-off function will fail to
operate.
In the case of liquid leaking from battery, be
sure to avoid eye contact with the liquid.
Blindness may occur. If the liquid enters your eye,
apply large amounts of water to wash and contact
a doctor immediately for treatment.
Do not apply a big shock to the batteries.
It may damage the battery and result in a short
circuit and excessive heat build-up.
Do not dismantle or modify the battery.
Dismantling the battery may cause liquid to leak
out.
Do not wet batteries and do not charge wet
batteries.

äáíáçå®
Do not charge dry cell batteries.
Primary batteries such as dry cell batteries cannot
be charged. Doing so may cause explosion or fire.
When handling a charger or connecting a
charger to an AC outlet, do not touch it with
wet hands.
Doing so may cause electric shock.
Please support recycling.
Nicad and nickel-metal hydride batteries are recyclable. Careless disposal may cause environmental
contamination.
