| ==== Low battery alarm: ====
| |
| When the transmitter battery voltage is lower than 4.2
| |
| V, the G.LED on the panel will flash slowly. Stop the running; replace the batteries for fresh ones.
| |
| ==== Power On ====
| |
| Follow the steps below to turn on the transmitter:
| |
| # Check to make sure that that battery is fully charged and installed correctly.
| |
| # Toggle the switch to the [ON] position. When active the red R.LED will be lit.
| |
| # Power on the receiver.
| |
| {{Note|type=error|'''Caution:''' For safety always power on the transmitter before the receiver.}}
| |
| ==== Binding the Transmitter and Receiver ====
| |
| The transmitter and receiver have already been bound at the factory.
| |
| However if the receiver needs to be replaced or additional receivers bound
| |
| follow these steps:
| |
| # Turn on the transmitter while holding the bind button to enter bind mode. Red G.LED will start flashing quickly. Once in bind mode release the bind button.
| |
| # Turn on your receiver (turn on the ESC switch); the receiver will enter bind mode automatically when powered on.
| |
| # Once binding is successful the receiver‘s LED will flash slowly
| |
| # Turn off the receiver and then your transmitter.
| |
| # Turn on your transmitter and then the receiver - and the receiver LED will glow red solid.
| |
| {{Note|type=info|'''Note:''' If the receiver red LED blinks quickly, the binding has not been successful. Repeat the above described steps once more.}}
| |
| ==== Channel Description ====
| |
| The transmitter outputs a total of 4 channels, which are allocated as follows:
| |
| * CH1: Steering Wheel – Connect the steering servo.
| |
| * CH2: Throttle Trigger – Connect the ESC (Electronic Speed Controller).
| |
| * CH3: Three-position Switch – Unused with GRT-10
| |
| * CH4: Button – Unused with GRT-10
| |
| ==== Channel Reverse Switches (ST.REV, TH.REV) ====
| |
| This function is used to adjust each channels direction of movement in relation to its input.<br>
| |
| The ST.REV / TH.REV switches are the reverse switches for CH1 and CH2.
| |
| {{Note|type=info|'''Note:''' The default setting for GRT-10: both ST.REV and TH.REV down.}}
| |
| ==== Steering and Throttle Trims ====
| |
| The trims serve for fine adjustment of the neutral (centre) positions of steering and throttle channels. One push of (+) or (-) button shifts the neutral
| |
| position by one step to one or the other side. The push of a button is also
| |
| signalled by a flash of the green G.LED: one flash means one step, dual flash
| |
| means the centre (zero) position of the trim. If there is no G.LED flash accompanying the button push, you have reached the end point of the trim range
| |
| in the given direction.
| |
| {{Note|type=info|'''Note:''' Normally, the throttle trim TH.TRIM should be left in the centre position. Only if your car moves forward or backward although the throttle trigger is in the neutral, push the TH.TRIM- or TH.TRIM+ until it stops.}}
| |
| ==== Steering Dual Rate ST.D/R ====
| |
| ST.D/R is for a quick steering servo travel adjustment; adjustment range:
| |
| 0-120% (step 5%). One push of ST.D/R- button decreases servo travel by one
| |
| step, ST.D/R+ increases servo travel (the push of a button is also signalled
| |
| by a flash of the green G.LED). If there is no G.LED flash accompanying the
| |
| button push, you have reached the end point of the steering range in the
| |
| given direction.
| |
| {{Note|type=info|'''Note:''' 0% D/R value means the steering servo does not move at all.}}
| |
| ==== Fail-safe ====
| |
| This function dictates what the receiver will do in the event that it loses
| |
| signal from the transmitter (the receiver LED starts blinking); it presets the
| |
| emergency servo/ESC position. For electric cars we strongly recommend setting the fail-safe for both steering and throttle to neutral (you car will stop
| |
| once the signal is lost). For nitro cars the throttle fail-safe should make the
| |
| brake engage.
| |
| Function Setting:
| |
| # Turn on the transmitter and make sure it is connected to the receiver.
| |
| # Hold the steering wheel and throttle trigger at the desired fail-safe position.
| |
| # Press and hold the BIND button for 3 seconds; the G.LED starts to flash for 2 seconds, indicating that the settings are successful.
| |
| {{Note|type=info|'''Note:''' The fail-safe function has not been set at the factory by default – you should set it accordingly during the initial set-up of your model. If no failsafe setting has been set, then the receiver will maintain the output of the last signal when the signal is lost.}}
| |
| {{Note|type=info|'''Note:''' Binding erases the previously set fail-safe stored in the receiver - you have to set the fail-safe again.}}
| |
| ==== Beginner Mode ====
| |
| Beginner mode is designed for the people who are new to the hobby. In this
| |
| mode the throttle has been limited to 50 percent.
| |
| ==== Function setting: ====
| |
| To switch between beginner and normal modes, press
| |
| and hold the CH4 button while turning the steering wheel completely counter clockwise as far as it can, and at the same time, power on the transmitter.
| |
| {{Note|type=info|'''Note:''' By default, the system is set to normal mode. If the system has set to beginner mode, the G.LED will be in a state of two-time flashing and on off, and keep the state for 3 seconds during power on.}}
| |
| === Preparing your car for the first run ===
| |
| ==== Turning on the Power ====
| |
| {{Note|type=warn|'''Remember:''' ALWAYS turn on the transmitter first and only then the receiver.}}
| |
| # Turn on transmitter first. Set both the steering and throttle trims to the centre (double blink); set the steering dual rates to max. (keep pushing the ST.D/R+ button until the G-LED stop blinking).
| |
| # Depending on the power pack you are using (NiMH or LiPo) set this type on the ESC; check the running mode is set to Forward/Brake/Reverse (refer to the ESC manual in the appendix).
| |
| # Connect the power pack to the speed controller in your car. Turn on the ESC switch. The receiver LED indicator should glow continuously red. If the receiver LED is flashing or does not light at all, the transmitter and receiver have not been paired. Refer to the „Binding the Transmitter and Receiver“ section.
| |
| # The ESC gives the ready signal (refer to the „ESC Throttle Range Calibration“ section). The car is ready for the first test.
| |
| ==== Transmitter Control Check and Trim Setup ====
| |
| # Turn the steering wheel to the left (counter clockwise); the front wheels of your car have to turn left. If the wheels turn right, flip the ST.REV reverse switch on the transmitter.
| |
| # With the steering wheel and trim in the centre the front wheels must point straight forward. If wheels point left, push the steering trim to the right. If wheels point right, push the steering trim to the left. (The front wheels actually have a slight toe-in or toe-out.)
| |
| # Pull the throttle trigger slightly just to see the wheels turning – your car has to go forward. Push (twice) the throttle trigger forward – your car has to go back. With the throttle trigger and trim in the centre the wheels may not spin. If this is not the case, refer to the „ESC Throttle Range Calibration“ section.
| |
| ==== Range Check ====
| |
| The range check should be performed in the beginning of each riding session, after any RC equipment change, after a heavy crash or whenever you
| |
| are in doubts on proper operation of your radio.
| |
| Ask a friend to take your model to the most distant place of the race track you
| |
| are going to ride on. The car has to respond without any delay to the control
| |
| inputs, they may be no servo buzzing or jitter, no drop outs. Do no try to
| |
| drive your car if the range test was not 100% successful.
| |
| ==== Fail Safe Setup ====
| |
| The receiver has a built in failsafe. The failsafe will automatically go to a pre-set position if the receiver lose radio signal from the transmitter or suffer any interference. If properly set up, the fail safe cuts the throttle to neutral so the car won’t go away under such circumstances.
| |
| # Turn on the transmitter and make sure it is connected to the receiver.
| |
| # Hold the steering wheel and throttle trigger at the desired fail-safe position.
| |
| # Press and hold the BIND button for 3 seconds; the G.LED starts to flash for 2 seconds, indicating that the settings are successful.
| |
| # The fail-safe check: Move the throttle trigger elsewhere from the neutral and turn off your transmitter. The ESC has to cut the throttle and stop the motor.
| |
| {{Note|type=info|'''Note:''' Any new binding will clear the previous fail-safe setting.}}
| |
| ==== Turning Off the Power ====
| |
| ALWAYS turn off the receiver first and only then turn off your transmitter.
| |
| If you switch off the transmitter first before the R/C car, you may lose control
| |
| of the R/C car.
| |
| # Turn off the ESC switch.
| |
| # Disconnect the battery connector from the speed control connector.
| |
| # Turn off the transmitter switch.
| |
| {{Note|type=warn|'''Warning:''' To avoid a possible fire hazard or ruining your battery, ALWAYS unplug the battery after use. Do NOT leave your vehicle unattended with the battery plugged in.}}
| |
| === Driving ===
| |
| * Driving an R/C car may take some time to master but here are some basic tips on driving:
| |
| * Drive your car in a large space, especially until you get the feel of driving the vehicle.
| |
| * Do not run on public streets or roads. This could cause serious accidents, personal injuries and/or property damage.
| |
| * Do not run in water or sand.
| |
| * If you keep pulling the throttle trigger on the transmitter, the vehicle will keep accelerating and run very fast. It is difficult to steer the vehicle running at high speed – try to run slowly being gentle on the throttle until you become used to driving.
| |
| * When the vehicle is running toward you, you need to operate the steering wheel in the opposite direction – take your time to get used to it.
| |
| * Practice turning the vehicle, referring to the following:
| |
| * Rather than just paying attention to the direction of the steering wheel, imagine that you are at the centre of the steering wheel, looking ahead of the vehicle, to turn in the direction you like.
| |
| * Once you become comfortable driving the vehicle, practice driving on a track with cones.
| |
| * Keep practising until you feel comfortable with the steering and throttle at low speed.
| |
| * Once you are feeling comfortable try using reverse.
| |
| * When you have mastered the basics you will be able to drive at higher speed having your car under control all the time.

| === Maintenance after driving ===
| |
| Proper maintenance is essential. Make sure to always perform appropriate
| |
| maintenance after driving so that you can enjoy driving without problems
| |
| next time.
| |
| # Always disconnect the battery pack and turn off the radio system when the car is not in use.
| |
| # Remove the sand, mud, dirt, and any other elements completely from the car before you store it.
| |
| # Never use chemicals or any solvents to clean the chassis as it may cause damage to the electronics components and plastic parts as well. Use compressed air, soft paintbrush, or toothbrush to clean dust and dirt.
| |
| # Inspect each part, screw and nut for loosening, missing or damage.
| |
| # You should always make sure the wheels are tightly secured and all moving or rotating parts move freely after and before use.
