Located on the left-hand side of the transmitter is thecharging jack that accepts only JR wall chargers. Please do not attempt to use any other brand of wall charger, as it may be reverse polarity and can cause damage to your system. Only use the JR wall charger when the XS3 isequipped with Ni-Cd batteries (JRPB958, available separately).Charging JackCharger Pigtail For TransmitterBlack To PositiveRed To NegativeJR TRANSMITTER CHARGE JACK POLARITY:RC Safety PrecautionsSteering Tension AdjustmentSteering tension is adjustable via the recessed screwlocated beneath the steering wheel (see page 7 for exactlocation). Turning the screw clockwise increases the steering tension.81.Radio control models are not toys. They are capableof inflicting serious injury to people and property. Usecaution at all times when operating your model.2.You are responsible for the safe operation of your RC model. You must properly install, test and operate your model with a clear sense of that responsibility. Do not take risks that might endanger yourself or others.3.Running an RC car in the streets is very dangerous to both drivers and models. Avoid running your model in areas occupied by full-size automobiles. To locate areas where you can safely operate your model, contact your local hobby shop for RC tracks or clubs in your area.4.When running an RC boat, keep it away from any swimmers, full-size boats and wildlife. Also, watch carefullyfor fishing lines that may get tangled in the propeller.5.Before operating your model, make sure your frequency is clear. If someone else is operating on the same frequency, both models will go out of control, possibly causing damage to the models, as well as others.6.If at any time while operating your RC model you sense abnormal model functioning, end your operation im-mediately. Do not operate your model again until youare certain the problem has been corrected.Caution: Control of your model is impossiblewithout sufficient voltage for the transmitter andreceiver. A weak transmitter battery will decreaseyour range of operation, and a weak receiver batterywill slow servo movement and decrease your rangeof operation. Check your receiver pack voltage oftento avoid losing control of your model. When usinga model that operates both the electric motor andthe receiver from the same battery (BatteryEliminating Circuitry or BEC), you should discon-tinue use when the top speed sharply decreases oryou’ll quickly lose control of your model. For safeand reliable performance of your RC model, pleasecarefully read and follow the guidelines below.xs3_5 10/31/02 3:13 PM Page 8
9 Your RS300 receiver is equipped with Battery EliminatorCircuitry (BEC). The receiver gets its power from themodel’s Ni-Cd battery pack, thus saving the weight of anadditional receiver battery. Ni-Cd batteries from 4.8–8.4V(4–7 cells) can be used safely. Higher voltage packs maydamage the receiver and servos.Note: When using a separate receiver Ni-Cd as apower source, the operating voltage range is4.8–6.0V (4- to 5-cell).Attention: Make sure the male and female connectorshave the correct polarity (+/-) before connecting. The servolead and receiver case are molded so that the lead can onlybe inserted correctly. Be sure to orient the servo plug cor-rectly for proper insertion.You may use a separate receiver battery to power thereceiver (such as for some electric boats or in gas-poweredvehicles). A Ni-Cd pack plugged into the battery socket onyour receiver will operate your receiver. You can also usealkaline batteries with the included battery box.If you use a mechanical speed controller, please make sureit has the correct connector for a BEC system (red connec-tor). See Figure A below for a typical setup. Most electronicspeed controllers are set up for BEC operation and plugdirectly into your receiver (Figure B). See Figure B for atypical setup and check your speed controller‘s manual forcorrect installation.Receiver/ Servo Connections and InstallationFigure A – Connections to BEC receiver with mechanical speed controller.

Receiver/ Servo Connections and InstallationOperating Your ModelIt’s important to learn the proper sequence for switchingon/off your radio system.Before OperationSwitch on the transmitter, then the receiver.After OperationSwitch off the receiver, then the transmitter. This ensuresthat you will always have a signal to the receiver and thatyour RC model will not operate out of control when youturn off the transmitter.10Your RS300 needs to be mounted so the receiver is isolatedand floats to avoid damage from shock or vibration.Placement of the RS300’s case should not come in directcontact with hard or rigid surfaces.1.Mount the RS300 receiver with double-sided tape. (Use extra layers of double-sided tape, particularly if it is thin,until you build up a cushioning pillow layer.) Do not use glue to mount the receiver!2.Run the antenna wire up through a plastic antenna tube and let the excess wire hang out the top of the tube.3.Do not cut, coil, or bundle excess antenna wire—range will be reduced!xs3_5 10/31/02 3:13 PM Page 10

Function ModeThrottle DeadbandThe throttle deadband feature is used to reduce/eliminatethe dead throttle area that exists at neutral to the startingpoint of throttle and from neutral to the starting point ofbraking. This area is sometime known as deadband. Asmore throttle trim (also known as static brake) is applied,more of the dead trigger area right off neutral exists. Toeliminate the throttle deadband, adjust a forward value suchthat your vehicle’s wheels just start to turn when the triggeris slightly squeezed. This provides the most accurate feeland eliminates the dead area in the throttle. To eliminate thebraking deadband, adjust the brake value such that yourvehicle starts to slow down when the trigger is slightlypushed. This provides the most accurate brake feel andeliminates the dead area when braking.Values: 0% to 100%Clear = 0%Accessing the Throttle Deadband Function1.Turn the transmitter power switch on.2.Press the Scroll key to access Function mode.3.Press the Scroll key until “TDB” appears on the screen4.Move the trigger accordingly to adjust the forward or braking deadband.5.Press the Increase or Decrease key to select the desired value necessary to eliminate dead area.6.Press the Scroll key to access the Exponential function.7.To exit the Function mode, either turn off the transmitter power switch or press the Scroll and Channel keys at thesame time.L/Ftdb0∞0∞R/BtdbForward Adjustment(depends on trigger position)Current ValueBrake Adjustment(depends on trigger position)Current ValuePress the Scroll key until "TDB" appears on thescreen.Press the Increase or Decrease key to select thedesired value necessary.SCROLLENTERCHANNELINCREASECLEARDECREASE21xs3_5 10/31/02 3:13 PM Page 21

The End-Point Adjustment range is from 0% to125% and is factory set to 100% for both channels. Thevalue displayed on the screen depends on the current position of the steering wheel, trigger, or trim lever to beadjusted.

Function ModeProgrammable MixingThe XS3 offers two different mixing adjustments that allowsfor mixing one channel to another channel. The mixesavailable are Steering-to-Auxiliary Channel Mixing andThrottle-to-Auxiliary Channel Mixing. Each direction isindependently adjustable. Popular use of this functionincludes 4-wheel steering and independent front and rearwheel brakes.For example, Throttle-to-Auxiliary channel mixing can beused for independent front and rear wheel brakes. Eachtime the throttle/brakes is moved, the auxiliary channel willmove in the direction and to the value input being given bythe throttle channel. Mixing is proportional, so small inputsto the throttle will result in small output from the auxiliarychannel. The adjustment range is from -125% to 0% to125%. If the rate is negative, the channel is mixed in theopposite direction.Both mixes share a single mixing “offset.” The purpose ofthe mixing offset is to redefine the neutral position of theauxiliary channel, which can be set using Grip Lever Awhen “LN” is selected in the Auxiliary Channel 3 function.If the “LN” selection is turned off in the Auxiliary Channel 3function with a offset value currently present, the value willcontinue to act as a mixing offset until the value is eithercleared or changed. If a mix is not required, it is stronglysuggested the mixing rate be set for 0%, which is thedefault.Accessing The Mixing Adjustment Function1.Turn on the transmitter power switch.2.Press the Scroll key to enter Function mode.3.Press the Scroll key until “MIX” appears in the screen.4.Press the Channel key to select the desired mix to be used.STR or STL = Steering-to-Auxiliary Channel 3 Mixing.THF or THB = Throttle-to-Auxiliary Channel 3 Mixing.5.Move the steering wheel or trigger in the desired direction for adjustment (left/right, forward/reverse or brake).Press the Increase or Decrease key to achieve the desired amount of mixing.
