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.

D.S.C. (Direct Servo Control)
By using D.S.C. sold separately to connect this
unit with a receiver, you can check the setting
without emission of radio wave on the course (pit).
D.S.C. sold separately (No. 1581 DSC (for
EX-1)) is required.
Not only the receiver supplied with this unit
but also the following receivers that support
D.S.C. can be used.
KR-297FZ (production finished)
KR-301F (production finished)
KR-302F/FS/FSC
When using a receiver other than the
supplied receiver, take care of the response
mode. (See "Switching the movement mode
(response mode)" on page 9.)
1Turn off the power of this unit.
2Remove the RF module and attach the D.S.C.
(sold separately).
3Remove the crystal from the receiver.
Be sure to remove the crystal from
the receiver. If not, a malfunction may
occur during the setting.

How to Use This Unit
Setting the trim and sub trim
Purpose of trim adjustment
"Trim" is a function of adjusting the servo neu-
tral position. When you try driving after loading a
steering servo, if the model does not run straight,
the steering trim must be adjusted. Also for the
throttle of engine car, the carburetor neutral posi-
tion must be corrected after loading the servo.
Adjustment of the neutral position is required not
only immediately after loading the servo but also
for adapting to change in driving such as wear of
tire and torsion of the chassis.
This unit provides two types of function menu for
this function: "Trim" (center trim) that adjusts only
the neutral position with the ends of operating
angle unchanged and "Sub trim" that moves the
ends of movement angle and the neutral position
together.
Trim (center trim)
When adjusting the neutral position during
driving, change the setting.
The steering trim can be set at "S:TRM" in the
function menu. (See page 15.)
The throttle trim can be set at "T:TRM" in the
function menu. (See page 23.)
Large movement may cause break of right and
left balance. If this case, readjust the sub trim
so that the trim becomes 0.
In the default state, "S:TRM" is assigned to the
ET1 over and "T:TRM" is assigned to the ET2
lever.

•
Sub trim
Adjust the sub trim when loading a servo or
carrying out test driving.
The steering sub trim can be set at "S:SUBTRM"
in the function menu. (See page 17.)
The throttle sub trim can be set at "T:SUBTRM"
in the function menu. (See page 25.)
Load a servo so that the set value of sub trim
does not become large.
Method of setting
1
Before loading a servo, adjust the center position.
2To center the trim with a servo loaded, adjust
"S:SUBTRM" and "T:SUBTRM."
3Carry out test driving to check the neutral
state.
If correction is required, adjust the sub trim.
4When the neutral position is fixed, use "S:
BALANC" to adjust the steering balance so
that the turning radius is the same for the right
and left. (See page 16.)
5Use "S:TRAVEL" to adjust the overall steering
angle. (See page 16.)
6During practice driving or a race, adjust the
trim at "S:TRM" and "T:TRM."
If the adjustment value becomes large,
readjust the sub trim so that the trim becomes
0.

The ends of movement
angle do not move.
Only the neutral position
moves.
Both the ends of move-
ment angle and the
neutral position move
simultaneously.

Adjusting the steering angle
Use a hexagon socket wrench (2 mm).
1Remove the sponge from the steering wheel.
2Insert the hexagonal socket wrench (2 mm)
into the two holes of steering wheel and
tighten the hexagon socket head screws.
Tighten evenly the right and left bolts.
3Attach the sponge to the steering wheel.
To return to the initial state, adjust the
hexagon socket head screw so that the tip
does not protrude from the tapped hole by a
small distance.
4Referring to page 45, set "#ADJVOL" (adjust
variable resistor).
