Operation Precautions

WarningProhibited Procedures

Do not operate outdoors on rainydays , run through puddles of water,or use when visibility is limited.

Should any type of moisture (water or snow) enter anycomponent of the system, erratic operation and lossof control may occur.

Do not operate in the followingplaces.

-Near people or roads.

-On any pond when boats are present.

-Near high tension power lines or communi-cation broadcasting antennas.

Interference could cause loss of control. Improper in-stallation of your Radio Control System in your modelcould result in serious injury.Do not operate this R/C system when

you are tired, not feeling well or underthe influence of alcohol or drugs.

Your judgment is impaired and could result in a dan-gerous situation that may cause serious injury to your-self as well as others.

Mandatory Procedures

Adjust the antenna vertically to the ground.

Otherwise, the operating range may become shorter.

Always perform an 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 cannot come in contact with anyobject. Walk away and check to see if the servos follow the movement of the controls on the transmitter. Should younotice any abnormal operation, do not operate the model. Also check to be sure the model memory matches themodel in use.

CautionProhibited Procedures

Do not touch the engine, motor, speed control orany part of the model that will generate heat whilethe model is operating or immediately after its use.

These parts may be very hot and can cause serious burns.

Never hold only the an-tenna.

Hold the grip handle, otherwise theantenna may be damaged.


When making adjustments to the model, do so with the engine not running or the motordisconnected.

You may unexpectedly lose control and create a dangerous situation.

(Turning on the power switches)Always check the throttle stick 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.

(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.

If the power switches are turned off in the opposite order the model may unexpectedly run out of control and causea very dangerous situation.

(Fail safe function) ---when using HRS modeBefore 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 failsafe 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 whenreception fails. However, if set to a dangerous position, it has the opposite effect.

Setting example: Throttle idle or brake position

NiCd Battery Handling Precautions (Only when NiCd batteries are used)

WarningMandatory Procedures

Always check to be sure your batter-ies have been charged prior to oper-ating the model.

Should the battery go dead while the model is operat-ing, loss of control will occur and create a very dan-gerous situation.

To recharge the transmitter and/or re-ceiver NiCd batteries, use the specialcharger made for this purpose.

Overcharging could cause the NiCd battery to over-heat, leak or explode. This may lead to fire, burns,loss of sight and many other types of injuries.

CautionProhibited Items

Do not use commercial AAsize NiCd batteries.

Quick charging may cause thebattery contacts to overheat anddamage the battery holder.

Do not short circuit the NiCd batteryterminals.

Causing a short circuit across the battery terminalsmay result in abnormal heating, fire and burns.

Do not drop the NiCd battery or ex-pose it to strong shocks or vibrations.

The battery may short circuit and overheat. Electrolytemay leak out and cause burns or chemical damage.

When the model is not being used,always remove or disconnect theNiCd battery.

Leaving the battery connected could create a dangeroussituation if someone accidentally turns on the receiverpower switch. Loss of control would occur.

SpecialCharger

ShockProhibited

NiCd AA sizebatteries.

Useprohibited

Do not throw NiCd batteries into afire. Do not expose NiCd batteries toextreme heat. Also do not disas-semble or modify a NiCd batterypack.

Overheating and breakage will cause the electrolyteto leak from the cells and cause skin burns, loss ofsight as well as other injuries.

When the system will not be used forany length of time store the systemwith batteries in a discharged state.Be sure to recharge the batteries priorto the next time the system is used.

If the batteries are repeatedly recharged in a slightlydischarged state the memory effect of the NiCd bat-tery may considerably reduce the capacity. A reduc-tion in operating time will occur even when the batter-ies are charged for the recommended time.

<NiCd Battery Electrolyte>The electrolyte in NiCd batteries is a strong alkali. Should you get even the smallest amount of theelectrolyte in your eyes, DO NOT RUB. Wash immediately with water and seek medical attention atonce. The electrolyte can cause blindness. If electrolyte comes in contact with your skin or clothes,wash with water immediately.

WarningConnector Connections

Be sure the receiver, servo and con-nectors are fully and firmly con-nected.

If vibration from the model causes a connector to workloose while the model is in operation, you may losecontrol .

Electronic speed controlInstall the heat sinks where they willnot come in contact with aluminum,carbon fiber or other parts that con-duct electricity.

If the Electronic speed control heat sinks touch othermaterials that conduct electricity a short circuit couldoccur. This could result in loss of control and damageto the system.

Receiver Vibration Damping andWaterproofing

(Car)Dampen the vibration to the receiverby mounting it to the chassis ormounting plate with thick, double-sided tape in electric powered mod-els. In gas powered models, wrap thereceiver in foam and mount it wherethe vibration is the least prevalent. (Boat)Dampen the vibration to the receiverby wrapping it in foam. Waterproof byplacing it in a plastic bag or make theradio box in your model watertight.

If the receiver is subjected to strong vibration or shockerratic or loss of control may occur. If any moisturecomes in contact the receiver and servos you mayexperience the same result as well as damage to thesystem.

Servo ThrowOperate each servo over its full strokeand be sure the linkage does not bindor is loose.

The continuous application of unreasonable force to aservo may cause damage and excessive batterydrain.

Servo InstallationWhen you install the servos alwaysuse the rubber grommets provided inservo hardware bags. Mount the ser-vos so they do not directly come incontact with the mount.

If the servo case comes in direct contact with themount, vibration will be directly transmitted to theservo.

If this condition continues for a long time the servomay be damaged and control will be lost.

Motor Noise SuppressionAlways install capacitors to suppressnoise when electric motors are used.

If capacitors are not properly installed you could expe-rience erratic operation and reduced range as well asloss of control.

Other Noise Suppression MethodsBe sure there are no metal parts inyour model which under vibrationcould come in contact with othermetal parts.

Metal to metal contacts under vibration will emit a highfrequency noise that will affect the receiver's perfor-mance. You could experience erratic operation andreduced range as well as loss of control.

Initial Set-Up

How to link the transmitter and the receiverEach transmitter has an individually assigned, unique ID code. In order to start opera-tion, the receiver must be linked with the ID code of the transmitter with which it isbeing paired. Once the link is made, the ID code is stored in the receiver and nofurther linking is necessary unless the receiver needs to be used with an other trans-mitter. (For T/R set, the link is already done at factory.)

Link procedure

1. Bring the transmitter and the receiver close to each other, within one meter.

2. Turn on the transmitter.

3. Check the LED that is placed on the back side of thetransmitter to see if the RF signal is transmitted.When the green LED is solid ON, the RF signal istransmitted.*Please refer the table below for LED status vs transmitter's condition.

LED status vs transmitter's condition:Parameter check for 0.5 seconds after power-on Red: OnTransmitting signals Green: OnF/S is activated by the F/S switch of the transmitter. (PPM mode) Green: BlinkUnrecoverable failure (EEPROM, etc.) Red and Green turn on alternatively.

4. Turn on the receiver.

5. Push the tactile switch of the receiver.

6. When the link is complete, the LED in the receiver changes to solid green.*Please refer the table below for LED status vs receiver's condition.

Functions

End point adjuster/EPAUse this when performing left and right steering angle adjustments, throttle high side/brake side operation amount adjustment, and channel 3 servo up side/down side op-eration amount adjustment during linkage.

- Corrects the maximum steering angle and left and right steering angles when thereis a difference in the turning radius due to the characteristics, etc. of the vehicle.

Maximum steering angleThe EPA function basically determines the maximum steering angle of each channel.The functions shown below may have been adjusted, or the operating range set byEPA function may be exceeded. Check the linkage each time the following functionsare adjusted.- Sub trim (all channels)- Throttle Acceleration (Brake side)- Brake mixing rate- Program mixing slave side (all channels)

ATL trimATL trim allows adjustment of the brake side operation amount during operation.Therefore, when the operating angle is adjusted with throttle EPA, ATL trim mustalso be taken into account.

WarningMake sure that the knuckle stopper is not contactedduring steering operation and that unreasonableforce is not applied to the servo during other channeloperation.

If unreasonable force is applied to the servo horn at the knuckle stopperduring steering operation, the servo may malfunction and the model mayrun out of control.

Decide the EPA valueat the contact point.

A slight clearance is required at the linkage, but thethrottle acceleration function acts to reduce the timelag caused by this clearance.

Throttle Acceleration / ACCGasoline engine cars have a small time lag at both the forward side and brake sidebecause a certain clearance is necessary at the linkage. Reducing this time lag at thetransmitter side provides the same sharp response as electric motor cars.

Operation- Operation near the throttle stick neutral positionbecomes a sharp rise.- The forward and brake sides can be set separately.
