In case of the High Response System (H.R.S) receiver R203HF, always use only the
following conditions:
Servo; 6V type Digital Servo only
Power supply; 6V Nicd battery
Transmitter setting; "HRS" mode
If the conditions are different, control is impossible.
And Fail Safe Unit (FSU1) is not available.
Operation Precautions
Warning
Do not operate two or more models
on the same frequency at the same
time.
Operating two or more models at same time on the
same frequency will cause interference and loss of
control of both models.
AM, FM (PPM) and PCM are different methods
of modulation. Nonetheless the same frequency
can not be used at the same point in time, regardless of the signal format.
Do not operate outdoors on rainy
days , run through puddles of water or
when visibility is limited.
Should any type of moisture (water or snow) enter any
compoent of the system, erratic opreation and loss of
control may occur.
Do not operate in the following
places.
-Near other sites where other radio control
activity may occur.
-Near people or roads.
-On any pond when rowboats are present.
-Near high tension power lines or communication broadcasting antennas.
Interference could cause loss of control . Improper installation of your Radio Control System in your model
could result in serious injury.
Do not operate this R/C system when
you are tired, not feeling well or under
the influence of alcohol or drugs.
Your judgment is impaired and could result in a dangerous situation that may cause serious injury to
yourself as well as others.
Mandatory Procedures
For Your Safety As Well As That Of Others
Prohibited Procedures
Extend the transmitter antenna to its full
length.
If the transmitter antenna is not
fully extended the operating
range of the radio will be reduced.
Always perform a operating range
check prior to use.
Problems with the radio control system as well as improper installation in a model could cause loss of control.
(Simple range test method)
Have a friend hold the model, or clamp it down or
place it where the wheels or prop can not come in
contact with any object. Walk away and check to
see if the servos follow the movement of the controls on the transmitter. Should you notice any abnormal operation, Do not operate the model. Also
check to be sure the model memory matches the
model in use.
Check the transmitter antenna to be
sure it is not loose.
If the transmitter antenna works loose, or is disconnected while the model is running signal transmission
will be lost. This will cause you to lose control of the
model..
Caution
Prohibited Procedures
Do not touch the engine, motor, speed control or any part of
the model that will generate heat while the model is operating
or immediately after its use.
These parts may be very hot and can cause serious burns.
For Your Safety As Well As That Of Others
Mandatory Procedures
Turning on the power switches.
Always check the throttle trigger on the
transmitter to be sure it is at the neutral
position.
1. Turn on the transmitter power switch.
2. Turn on the receiver or speed control
power switch.
When making adjustments to
the model do so with the engine not running or the motor
disconnected.
You may unexpectedly lose control and
create a dangerous situation.
Turning off the power switches
Always be sure the engine is not
running or the motor is stopped.
1. Turn off the receiver or speed control power switch.
2. Then turn off the transmitter power switch.
When operating your model
always display a frequency
flag on your transmitter antenna.
If the power switches are turned off in the opposite
order the model may unexpectedly run out of control
and cause a very dangerous situation.
When adjusting the transmitter on land while preparing to run (cruise), take measures
so that the wind will not knock over the transmitter.
If the transmitter is knocked over, the throttle stick may be accidentally set to the operating position and you may
lose control.
(Fail safe function) ---H.R.S or PCM mode only
Before running (cruising), check the fail safe function.
Check Method;
Before starting the engine, check the fail safe function as follows:
1) Turn on the transmitter and receiver power switches.
2) Wait at least one minute, then turn off the transmitter power switch. (The transmitter automatically transfers the fail
safe data to the receiver every minute.)
3) Check if the fail safe function moves the servos to the preset position when reception fails.
The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when
reception fails. However, if set to a dangerous position, it has the opposite effect. When the reverse function was used
to change the operating direction of a servo, the fail safe function must be reset.
Setting example: Throttle idle or brake position
Nicad Battery Handling Precautions
(Only when Nicad batteries are used)
Warning
Always check to be sure your batteries have been charged prior to operating the model.
To recharge the transmitter Nicad ,
use the special charger made for this
purpose.
Should the battery go dead while the model is operating loss of control will occur and create a very dangerous situation.

Installation Safety Precautions
Warning
Connector Connections
Be sure the receiver, servo, crystal
and connectors are fully and firmly
connected.
If vibration from the model cause a connector to work
loose while the model is in operation. You may lose
control .
Receiver Vibration Damping and
Waterproofing
Installation
(Car)
Dampen the vibration to the receiver
by mounting to the chassis or mounting plate with thick double sided tape
in electric powered models. In gas
powered models wrap the receiver in
foam and mount it where the vibration
is the least prevalent.
(Boat)
Dampen the vibration to the receiver
by wrapping it in foam. Waterproof by
placing it in plastic bag or watertight
radio box in model.
Install the heat sinks where they will
not come in contact with aluminum,
carbon fiber or other parts that conduct electricity.
If the FET Amp (Electronic speed control) heat sinks
touch other materials that conduct electricity a short
circuit could occur. This could result in loss of control
and damage to the system.
Servo Throw
Operate each servo over its full stroke
and be sure the linkage does not bind
or is loose.
The continuous application of unreasonable force to a
servo may cause damage and excessive battery
drain.
Servo Installation
When you install the servos always
use the rubber grommets provided in
servo hardware bags. Mount the servos so they do not directly come in
contact with the mount.
If the receiver is subjected to strong vibration or shock
erratic or loss of control may occur. If any moisture
comes in contact the receiver and servos you may
expertise the same result as well as damage to the
system.
If the servo case comes in direct contact with the
mount vibration will be directly transmitted to the
servo.
Receiver Antenna
Motor Noise Suppression
Do not cut or bundle the receiver antenna
Do not bundle the receiver antenna
together with the servo lead wires
Keep the receiver antenna at least 1
inch away from the motor and battery
and wires that handle heavy current
loads..
Cutting, bundling or routing the receiver antenna near
any devise that produce noise will reduce the operating range of the system and result in loss of control.
*Also route the receiver antenna away from metal,
carbon fiber and other parts that conduct electricity. These parts can transmit high frequency noise.
28
Electronic speed control
If this condition continues for a long time the servo
may be damaged and control will be lost.
Always install capacitors to suppress
noise when electric motors are used.
If capacitors are not properly installed you could experience erratic operation and reduced range as well
as loss of control.
Other Noise Suppression Methods
Be sure there are no metal parts in
your model which under vibration can
come in contact with other metal
parts.
Metal to metal contacts under vibration will omit a high
frequency noise that will effect the receivers performance. You could experience erratic operation and
reduced range as well as loss of control.
Initial Set-Up
Preparations (Transmitter)
Before setting the transmitter functions, check and set items 1 to 3 below.
(Display when power switch turned on)
When the power switch is turned on, the currently selected model number is displayed. Check if this number is the model number you want to set-up. To change the
model number, use the Model Select function (page ).
Turn on the transmitter power.
Initial Set-Up
(Start screen)
The model number is displayed.
1. RF Output Check
If signals are output normally, RF output monitor "RF"
will be displayed on the screen.
If RF is not displayed, check if the transmitter crystal and
RF module are installed.
If the transmitter is abnormal or faulty, contact your
Futaba dealer.
"RF"
29
2. Modulation Mode Check
The T3PK transmitter output signal format can be
changed to match the type of receiver. Check if the
modulation mode is set to match the receiver used.
When using an FM receiver (e.g., R133F), the modulation mode must be set to PPM. When using a PCM receiver (e.g., R113iP), the modulation mode must be set
to PCM. When using a H.R.S receiver (e.g., R203HF),
the modulation mode must be set to HRS. If this setting
is incorrect, change it with the HRS/PCM/PPM Select
(page ) function.
3. Trims Initial Set-Up
Initial Set-Up
30
- Steering trim (DT1) check
At initial set-up, steering trim is assigned to digital trim
DT1 above the steering wheel. Operate the DT1 lever
and check if the steering trim display on the screen
changes. After checking the trim, set the trim display to
the center (N) position.
- Throttle trim (DT2) check
At initial set-up, throttle trim is assigned to digital trim
DT2 at the left side of the steering wheel. Operate the
DT2 lever and check if the throttle trim display on the
screen changes. After checking the trim, set the trim
display to the center (N) position.
(PPM)
- Steering dual rate (DL1) check
At initial set-up, steering dual rate is assigned to grip
dial DL1 (upper) at the grip of the transmitter. Operate
the DL1 dial and check if the D/R value displayed on
the screen changes. After checking D/R, set the steering dual rate to 100%.
(Set-Up Procedure When Installed In a Car)
When installing the servos in a car, performing function set-up in the following order
is recommended.
Initial Set-Up
- Throttle ATL (DL2) check
At initial setting, throttle ATL is assigned to grip dial
DL2 (lower) at the grip of the transmitter. Operate the
DL2 dial and check if the ATL value displayed on the
screen changes. After checking ATL, set throttle ATL
to 100%.
1. Perform step 3. Trims Initial Set-Up of Preparations on the
preceding page.
2. Set the servo direction of operation using the Reverse
function. (Page )
The servo installation method and linkage direction depends
on the kit. Therefore, the servo operation direction may have
to be reversed relative to transmitter operation. Before installing the servo, check the operating direction and set it using the Reverse function.
3. Set the subtrim and adjust the servo neutral point. (Page )
4. Set the trigger travel by adjusting the throttle trigger mechanical ATL to you liking. (Page )

Throttle speed/TH-SPEED (Throttle system)
Sudden trigger operation on a slippery road only
causes the wheels to spin and the vehicle cannot accelerate smoothly. Setting the throttle speed func- TH-SPEED/Smooth, quick starts possible
tion reduces wasteful battery consumption while at
the same time permitting smooth, enjoyable operation.
No TH-SPEED/Tires slip and vehicle does not move
Operation
Throttle servo (amp) operation is delayed so that the drive wheels will not spin even
if the trigger is operated more than necessary. This delay function is not performed
when the trigger is returned and at brake operation.
- Low side throttle speed (See [Operation range setup].)
Use when adjusting the speed from the neutral position to the set point.
- High side throttle speed (See [Operation range setup].)
Use when adjusting the high side speed from the set point.
Remark: Regarding the throttle speed set value; the actual delay value varies
depending on the system (HRS, PCM, PPM). The delay when the HRS system is used is approximately 1/
3 that of the PCM and PPM systems.
Switch setting
Use PS1, PS2, or PS3 to switch the throttle speed function ON/OFF.

A.B.S. Function
When the brakes are applied while cornering with a 4 Wheel
Drive or other type of vehicle, understeer may occur. The
generation of understeer can be eliminated and corners can
be smoothly cleared by using this function.
Operation
- When the brakes are applied, the throttle servo will pulse
intermittently. This will have the same effect as pumping
the brakes in a full size car.
- The brake return amount, pumping cycle, and brake duty
can be adjusted.
- The region over which the ABS is effective can be set according to the steering operation. (Mixing function)

Fail Safe Unit
When the 3PK is used with the Futaba fail safe unit (FSU-1), it will operate as described below.
- When the FSU-1 is connected to the throttle channel, and the A.B.S. function has
been activated, the FSU-1 LED will flash each time the servo operates. The reason
for this is that the FSU-1 responds to sudden data changes caused by A.B.S. function
pumping operation. It does not mean that the fail safe function is activated. The servo
will not be affected.
