4690478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDETRTRTRThe Lap Times menu displays a total of up to 99 laps that are recorded using the Lap Timer function. Each Lap Time is displayed along with the Best Lap Time and the Total (Cumulative) Lap Time.Viewing Lap Times:1) From the Top Screen, press the ENTER key to open the Programming Menu list.2) Scroll UP or DOWN to highlight the LAP menu, then press the ENTER key. The LAP menuwill be displayed and the last Lap selected will be highlighted.3) Scroll UP and DOWN to view the stored Lap Times. Lap Times are stored from the timeyou start the Lap Timer to the time you Stop the Lap Timer. The Total (Cumulative) LapTime and your Best Lap Time are always displayed at the top of the list.Lap Times are stored until you restart the Lap Timer function. When the Lap Timer function is restarted, old Lap Times are cleared and new Lap Times are stored.The Fail Safe function automatically moves the servos to a predetermined position in the event that the signal between the transmitter and the receiver is interrupted, whether due to signal degradation or to low transmitter battery. Several different setting options are available. The Fail Safe function can be set to Hold the servos in the last position they were in when the signal was lost, or each of the servos can be set to move to a custom position when the signal is lost. For example, the throttle servo moves to the Brake Side to engage the brakes and stop your model. If you're driving a gas- or glow-powered boat, the Fail Safe function could be set to lower the throttle to idle and turn the rudder slightly left or right so that the boat will continue in slow circles.In addition, a Receiver Battery Voltage Fail Safe function is available which allows you to set a custom voltage that the Receiver Battery Fail Safe function will Activate at. This is useful if you're using servos with a higher than normal current draw that might run out of power before the receiver does.Setting the Fail Safe:Fail Safe settings can be programmed for each of the four channels individually. In addition, Fail Safe settings are model-specific, meaning you can have different Fail Safe settings for each Model in memory. Three Fail Safe options are available for each channel as described below:FREE - Fail Safe is disabled for this channel. Servos can move freely when the signal is lost.HOLD - When Fail Safe Activates, the servo will be held in the last position it was in when the signal was lost. % (PERCENTAGE) - When Fail Safe Activates, the servo will travel to the programmed position when the signal is lost.IMPORTANT: The Fail Safe function will NOT OPERATE if the receiver loses power. It will operate only if the transmitter and receiver signal is interrupted or if the transmitter loses power.1) From the Top Screen, press the ENTER key to open the Programming Menu list.2) Scroll UP or DOWN to highlight the F/S menu, then press the ENTER key. The F/S menuwill be displayed and [ST]:FREE will be highlighted.3) Scroll UP or DOWN to highlight the desired channel you would like to change the FailSafe option for.4) Press the ENTER key, then scroll UP or DOWN to choose the desired Fail Safe option forthat channel. If you choose to program a % value, see step 5 below.F/S setting range is FREE, HOLD, or %. The default setting is FREE.13.LAP (LAP TIMES)PROGRAM14.F /S (FAIL SAFE)PROGRAMMT-4S User's Guide.indd 46 2015/10/27 14:39:06
47TRTRTR90478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDE5) To program a Fail Safe percentage value, move the control the amount you want theservo to move to when the Fail Safe function Activates and HOLD it in that position,then press and HOLD the ENTER key until an audible tone sounds. The percentage anddirection the servo will travel will be displayed. For example, to set the Throttle Brake toengage when the Fail Safe function Activates, push the throttle trigger toward the Brakeside the desired amount, HOLD the throttle trigger in that position, then press and HOLDthe ENTER key. The percentage value programmed will be indicated by two hash markson the Servo Monitor.6) Check to ensure your Fail Safe settings are working properly. Make sure that both the transmitter and receiver are turnedON, then, while someone is holding your model, turn the transmitter OFF. The servos should react correctly based on theFail Safe values chosen.The Fail Safe settings will be retained even if the transmitter loses power or if the transmitter and receiver must be paired again.When using an FH2 receiver with your transmitter, these Fail Safe features are not supported. In this case, the Fail Safe function must be programmed directly through the receiver. For more information, follow the Fail Safe Programming instructions provided with your FH2 receiver.14.F /S (FAIL SAFE)PROGRAMPROGRAMSetting the Receiver Battery Voltage Fail Safe Function:The Receiver Battery Voltage Fail Safe function is designed to alert you when your receiver battery requires recharging. This ensures that the receiver battery's voltage doesn't drop so low that your servos aren't provided adequate voltage to operate optimally. When Activated, the throttle servo will move to the predetermined position you programmed in step 5 in the Setting the Fail Safe section above. If this occurs, recharge or replace your receiver batteries.If FREE or HOLD is chosen for the Throttle channel, you cannot Activate the Receiver Battery Voltage Fail Safe function. A % value must be chosen for the Throttle channel to be able to program and use the Receiver Battery Fail Safe function.The Receiver Battery Voltage Fail Safe function works only with FH3 and FH4T receivers.1) Follow steps 1 through 5 in the Setting the Fail Safe section to program a Throttle FailSafe percentage value.2) From within the F/S menu, press the ENTER key, then scroll DOWN to highlight[B-F/S] OFF.3) Press the ENTER key, then scroll UP or DOWN to choose the desired Receiver BatteryFail Safe Voltage value. Many factors, such as the current draw of your servos and howmany servos you're using, etc., will determine the value to use. A good starting pointwould be 3.7V. If it appears your servos are slow or not producing adequate torque whatthat Voltage value is reached, Increase the Voltage value.WARNING: This function is designed for use with glow- or gas-powered Models that use a separate receiver battery pack. Do NOT use this function with an electric Model that uses the motor battery to power the servos and receiver.F/S B-F/S setting range for FH4T receivers is OFF and 3.5V to 7.4V. F/S B-F/S setting range for FH3 receivers is OFF and 3.5V to 5.0V. The default setting is OFF regardless of the Modulation Type chosen.The Telemetry Log function allows you to view a log of the Telemetry Data that is sent from the receiver to the transmitter. You are able to view Telemetry Data for both Temperature outputs, the RPM output and the receiver's Voltage. This information can be used to track specific information about your model, such as cylinder head temperature if you're running a nitro-powered model or battery temperature if you're running an electric model and much more. The interval that Telemetry Data is read and stored can be adjusted so that Telemetry Data can be stored for up to 90 minutes of use. The Telemetry Log can store 120 different data entries at intervals ranging from 00.1 seconds to 45.9 seconds. 15.LOGGER (TELEMETRY LOG)PROGRAMMT-4S User's Guide.indd 47 2015/10/27 14:39:06

5290478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDETRTRTRThe Binding function allows you to Bind the transmitter and receiver pair. When new, it is necessary to pair the transmitter and receiver to prevent interference from transmitters operated by other users. This operation is referred to as Binding. Once the Binding process is complete, the setting is remembered even when the transmitter and receiver are turned OFF. Therefore, this procedure usually only needs to be done once. In addition, the Modulation Type and Servo Operating Mode can also be changed to suit your specific setup.Changing the Modulation Type:The Modulation Type function allows you to choose the transmitter Modulation Type. The Modulation Type can be changed to match the receiver you're using. For example, if you wish to use an Airtronics 2.4GHz FH2 receiver with your transmitter, you would need to change the Modulation Type to FH2 prior to Binding your transmitter and receiver. Modulation Type is model-specific, meaning that you can have one model use FH4T Modulation and another model use FH2 Modulation, etc.The Modulation Type must be chosen prior to Binding the transmitter and receiver. Make sure the Modulation Type you choose matches the Modulation Type of the receiver you're using.1) From within the SYSTEM menu, scroll UP or DOWN to highlight the BIND menu.The following Modulation Type options are available:FH2 - Select this Modulation Type when using an Airtronics 2.4GHz FH2 surface receiver. FH3 - Select this Modulation Type when using an Airtronics 2.4GHz FH3 receiver.FH4T - Select this Modulation Type when using an Airtronics 2.4GHz FH4T Telemetry receiver. FH3F/FH4FT - These Modulation Types are NOT used in North America. They are typically used in France.2) Press the ENTER key. The BIND menu will be displayed and [RF MODE]:FH4T will behighlighted.3) Press the ENTER key, then scroll UP or DOWN to select the desired Modulation Type,then press the ENTER key a second time. Set to (Modulation Type) NO/YES will bedisplayed.4) Scroll DOWN to highlight YES, then press the ENTER key.02.BIND (BINDING, MODULATION TYPE AND SERVO OPERATING MODE)SYSTEMChanging the Channel Mode - FH2 Modulation Type Only:When the FH2 Modulation Tyep is selected, you can choose to operate the transmitter in either 2-Channel Mode or 4-Channel Mode. This option is available ONLY when [RF MODE] FH2 is selected.1) From within the BIND menu, scroll DOWN to highlight [CH]:4ch.2) Press the ENTER key, then scroll UP or DOWN to choose the desired Channel Mode.Selecting 2CH will enable 2-channel operation (Steering and Throttle). Selecting 4CHwill enable 4-channel operation (Steering, Throttle, Auxiliary 1 and Auxiliary 2).BIND CH setting range is 2CH and 4CH. The default setting is 4CH. IMPORTANT: Not all BIND menu functions are supported by all Modulation Types. Only supported functions will be displayed once a Modulation Type is chosen. For example, the FH2 Modulation Type does not support the ability to change the Servo Operating Mode.Changing the Servo Operating Mode:The Servo Operating Mode function is used to optimize the radio control system to suit the type of servos you're using in your model. For example, using the SHR setting with Digital servos will Increase the servo's response time, even above the manufacturer's stated specification. If you're using Airtronics SRG Digital servos, you can use the SSR setting for the fastest response time. The combination of using Digital servos and using the correct Servo Operating Mode results in the ultimate feel and response, making you feel more in control of your model than ever.MT-4S User's Guide.indd 52 2015/10/27 14:39:09

Choose from either [ST]:NOR(Steering), [TH]:NOR (Throttle), [A1]:NOR (Auxiliary 1) or [A2]:NOR (Auxiliary 2).02.BIND (BINDING, MODULATION TYPE AND SERVO OPERATING MODE)SYSTEMIMPORTANT INFORMATION ABOUT SERVO OPERATING MODES:If you're using Analog servos in your model, DO NOT use SHR or SSR Servo Operating Mode for those channels. Use the NOR (Normal) Servo Operating Mode with Analog servos. Using SHR or SSR Servo Operating Mode with Analog servos can result in poor performance or even damage to the servos or the receiver! In some cases, the servo may not operate at all.Not all ESCs are compatible with SHR or SSR Servo Operating Modes. If your ESC does not operate correctly, change the Servo Operating Mode to NOR (Normal) for that channel (or channels).SHR and SSR Servo Operating Modes should only be used with Digital servos. While the SHR Servo Operating Mode can be used with any brand of Digital servo, the SSR Servo Operating Mode should ONLY be used with Airtronics SRG Digital servos.2) Press the ENTER key, then scroll UP or DOWN to choose the desired Servo OperatingMode option for that channel.SERVO OPERATING MODE setting range is NOR, SHR and SSR. The default setting is NOR. SSR Operating Mode is not supported when the FH3 or FH3F Modulation Type is selected. No Servo Operating Modes are supported when the FH2 Modulation Type is selected.Binding the Transmitter and Receiver:To Bind the transmitter and receiver, please see the Transmitter and Receiver Binding section on page 16. Prior to Binding the transmitter and receiver, make sure to choose the desired Modulation Type that matches the receiver you're using. Servo Operating Mode can be changed prior to Binding the transmitter and receiver, or after the Binding process.SYSTEMTrm1 - Steering TrimTrm2 - Throttle TrimTrm3 - Steering Dual RateTrm4 - Brake Dual RateSw1 - Telemetry Logger ON/OFFSw2 - Timer ON/OFFDial Knob - Auxiliary 1 Channel 3Auxiliary Lever - Auxiliary 2 Channel 4The Key Assignments function allows you to assign different functions to each of the two Push-Button Switches, the four Trim Switches, the Dial Knob and the Auxiliary Lever.

5890478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDETRTRTRChanging the Auxiliary Lever Function:In general, the Auxiliary Lever is used to control Auxiliary 1 Channel 3 or Auxiliary 2 Channel 4. Adjusting the High and Low Tweak values determines how far and in which direction the Auxiliary servo travels when the Auxiliary Lever is moved Up and Down. For example, if you assign AUX2 to the Auxiliary Lever and adjust the Tweak values to +50 and -50, the Auxiliary 2 servo will be centered when the Auxiliary Lever is centered and will travel 50% in one direction when the Auxiliary Lever is moved Up and travel 50% in the other direction when the Auxiliary Lever is moved Down. This allows you to use the Auxiliary Lever like a 2- or 3-position switch. In addition, the Auxiliary Lever can be used to control the same parameter functions as the Trim Switches and the Rotary Dial. For example, if you assign TRIM-ST and adjust the Tweak values to +100 and -100, the Auxiliary Lever will control Steering channel Trim. The direction and amount the Trim moves when you move the Auxiliary Lever Up or Down is dependent on the Positive and Negative Tweak values.To control either the Auxiliary 1 or the Auxiliary 2 servos using the Auxiliary Lever, the Auxiliary Type in the AUX TYPE menu must be either STEP AUX or POINT AUX. For more information, see the Auxiliary Type section on pages 59 and 60.1) From within the KEY ASSIGN menu, scroll UP or DOWN to highlight LEVER.2) Press the ENTER key. The LEVER menu will be displayed and FUNCTION AUX2 will behighlighted.3) Press the ENTER key, then scroll UP or DOWN to choose the desired function for theAuxiliary Lever.

Instead, the current position of the Auxiliary Lever is displayed on the Top Screen.03.KEY ASSIGN (KEY ASSIGNMENTS)SYSTEM1) From within the LEVER menu, scroll DOWN to highlight TWEAK(H) +100.2) Press the ENTER key, then scroll UP or DOWN to choose the desired High Side Tweakvalue. Increasing the Tweak value will increase servo travel in the High Side directionand decreasing the Tweak value will decrease servo travel in the High Side direction.Using a negative value will change the direction of servo travel.LEVER TWEAK(H) setting range is -100 to +100. The default setting is +100.Changing the High and Low Tweak Values:The High and Low Tweak values determine the direction and amount of Auxiliary 1 or Auxiliary 2 servo travel. In addition, the High and Low Tweak values determine the direction and amount of parameter function changes, such as Steering Trim or the Anti-Lock Braking Point percentage value.3) Scroll DOWN to highlight TWEAK(L) -100.4) Press the ENTER key, then scroll UP or DOWN to choose the desired Low Side Tweakvalue. Decreasing the Tweak value will increase servo travel in the Low Side directionand increasing the Tweak value will decrease servo travel in the Low Side direction.

When you apply Trim to a servo, the Neutral Point of the servo shifts toward the High Side or the Low Side. When you do this, the servo travels less in one direction and more in the other direction because the servo End Points are stationary. In order to balance the servo travel, you would need to manually readjust the servo End Points. Using the Trim Type function allows you to make the servo End Points shift toward the High Side or the Low Side when you apply Trim. This maintains balanced servo travel without the need to manually readjust the servo End Points.The Trim Type function does not effect servo Sub-Trim. It only effects servo Trim that's input using the Trim Switches, Rotary Dial or Auxiliary Lever. Servo Sub-Trim, which is different, always uses Parallel Trim.Two Trim Types are available: CENTER - When Selected, servo End Points are stationary. In order to balance servo travel, you would need to manually readjust the servo End Points, if desired.PARALLEL - When Selected, servo End Points shift toward the High Side or the Low Side automatically when you apply Trim. This maintains balanced servo travel without the need to manually readjust the servo End Points. 2) Press the ENTER key. The TRIM TYPE menu will be displayed and [ST] CENT will behighlighted.3) Scroll UP or DOWN to highlight the desired channel you would like to change the TrimType option for.

This setting does not effect the RPM or Speed Digital Display.The RPM Gauge and RPM/Speed Digital Display names will change from RPM to MPH or KM/H depending on the RPM Unit value chosen.10.TELEMETRY (TELEMETRY DISPLAY OPTIONS)SYSTEMThe Maximum Voltage value cannot be set lower than the Alert Voltage value. If necessary, you may need to lower the Alert Voltage value prior to lowering the Maximum Voltage value.TELEMETRY MAX VOLT setting range is 3.0v to 9.0v. The default setting is 9.0v.3) Press the ENTER key, then scroll UP or DOWN to change the Maximum Voltage value.The Voltage Display Monitor on the Telemetry Screen will not display receiver batteryVoltage values above the Maximum Voltage value programmed.Changing the Alert Voltage Value:The Alert Voltage value determines the voltage at which the Voltage Alert alarm will sound. For example, you can set the Alert Voltage value to alert you to when your model's receiver battery is getting low and needs to be recharged. When the Alert Voltage value is reached, the Voltage Alert alarm will sound and LED2 (Red) will flash. The Voltage Alert alarm will sound for approximately 5 seconds, however, LED2 will continue to flash until you recharge the receiver battery. The audible portion of the Voltage Alert alarm can be cleared by pressing the BACK/CANCEL key or the Push-Button Rotary Dial. In general, the Alert Voltage value should be high enough to alert you when it's time to recharge your receiver battery, but not so low that the receiver battery loses power and can no longer control your model.RPM SETTING (RPM and Speed Telemetry Display Options)MT-4S User's Guide.indd 66 2015/10/27 14:39:17

Temperature and RPM Sensors can be installed into your model to give you Temperature and RPM or Speed feedback in real-time displayed on the transmitter's Telemetry Screen.The range of the Telemetry System is approximately 260 feet (80 meters), although the range can vary based on many environmental factors. Use the Telemetry Signal Indicator to determine the quality of the Telemetry Signal.When used with an Airtronics 2.4GHz FH4T Telemetry-capable surface receiver, such as the RX-461 or RX-462, and up to two Temperature Sensors and an RPM Sensor (all available separately), Telemetry Data, such as RPM or Speed, Temperature, and Receiver Voltage can be viewed on the M12 transmitter's Telemetry Screen. This section details connecting the RPM and Temperature Sensors to the RX-461 and/or RX-462 receiver and how to mount those Sensors into your model. For more information about the specifics of either receiver, refer to the User's Guide included with your receiver.For more information about viewing Telemetry Data on the Telemetry Screen, see the TELEMETRY Screen section on pages 14 and 15. For more information about choosing Telemetry options, see the Telemetry Display Options section on pages 63 through 68.Plugging the Telemetry Sensors into the Receiver:1) Carefully pry up and remove the plastic cover from over the Telemetry Sensor Input Ports on the receiver.2) Plug the Telemetry Sensor(s) into their respective Input Ports in the receiver. The Temperature Sensor can be plugged intoeither the TEMP 1 or the TEMP 2 Input Port and the RPM Sensor is plugged into the RPM Input Port. The Sensor Plugs areindexed so they can be plugged in only one way.Make sure to push the Sensor Plugs firmly in place to ensure a good connection. When routing Sensor Wires inside your model, be careful that they cannot come into contact with any moving parts. The Sensor Wires should be securely mounted and protected against damage.In addition, install the dust covers included with your receiver to prevent dirt and debris from getting into any unused Input Ports.MT-4S User's Guide.indd 69 2015/10/27 14:39:18
7090478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDETRTRTRTELEMETRY CONNECTIONS AND MOUNTING REFERENCE1) Mount the RPM Sensor to an aluminum or ABS angled bracket, then mount the bracket to your model, making sure that it'sheld securely in place.Mounting the RPM Sensor:The RPM Sensor uses infrared technology to record RPM data from a rotating part, such as a flywheel or a spur gear. One Black and one White reflective decal is included that is attached to the rotating part so the Sensor Pickup can 'see' it.Sensor PickupInput PlugReflective DecalAngled BracketRPM SensorSensor PickupSpur Gear or Other Rotating Part~1mmSensor PickupMounting the Temperature Sensor:1) Secure the Sensor End directly against the part of your engine, motor, battery or other object you want to monitor temperature readings from, using either a nylon cable tie or high-temperature clear tape. For example, to monitor the cylinder headtemperature of your glow- powered model, the best place to secure the Sensor End is where the bottom of the cylinder head meets the top of the engine case. The Sensor End can be held in place using a nylon cable tie wrapped around your engine. To monitor the temperature of your battery pack or electric motor, high-temperature clear tape can be used to secure the Sensor End to the exact spot you want to monitor.Sensor EndInput PlugAttach withHigh-Temperature Clear Tape2) Cut one of the two reflective decals included with the RPM Sensor into an ~2mm diameter and apply it to the rotating part,so that as the part rotates, the reflective decal passes in Front of the Sensor Pickup. If the rotating part is metallic-colored(silver, aluminum, chrome, etc.), use the Black reflective decal and if the rotating part is dark-colored (black, blue or anotherdark color), use the White reflective decal.IMPORTANT: For optimal operation, the Sensor Pickup should be positioned approximately 1mm away from the rotating part (flywheel, spur gear, pinion gear etc.)After installing the RPM Sensor and connecting it to your receiver, the RPM Sensor must be calibrated. For more information, see the RPM and Speed Telemetry Display Options section on pages 63 through 68.IMPORTANT: When installed, it's important that the Sensor Pickup face the rotating part and that the Black or White reflective decal is positioned so that it passes in Front of the Sensor Pickup. It's also important that the reflective decal contrasts with the rotating part it's applied to and that the Sensor Pickup is mounted approximately 1mm away from the rotating part.IMPORTANT: If the Sensor Wires are not long enough for your specific application, you can carefully splice in extra wire of similar gauge to extend the Sensor Wires to the desired length. Make sure to solder the splices securely together and protect the splices using heat-shrink tubing.MT-4S User's Guide.indd 70 2015/10/27 14:39:19

For example, if your model requires a separate 3-position or more switch to operate a feature, the Point Auxiliary function can be customized to control this.Point Setting: Locates the actual point in the servo travel that you want a specific programming setting to occur. This setting can vary depending on the actual programming setting the Point setting is controlling.Power Switch: Turns the transmitter ON and OFF.Push-Button Rotary Dial: The Push-Button Rotary Dial (also referred to as the Up Key, Down Key, or Enter key) is used along with the BACK/CANCEL Key to facilitate transmitter programming. It allows you to quickly and easily navigate the various Programming and System Menus and switch between the Top Screen and the Telemetry Screen.Push-Button Switch: The transmitter features two separate Push-Button Switches in different locations (Sw1 and Sw2). Each Push-Button Switch is programmable and will perform a different function depending on what function is assigned to it.Receiver Battery Voltage Fail Safe: Used to set a custom voltage that the Receiver Battery Fail Safe function will Activate at. When your receiver battery voltage drops to the programmed voltage, the throttle servo will move to the predetermined position programmed using the Fail Safe function. If this occurs, recharge or replace your receiver batteries.Receiver Voltage Display: Displays the current voltage of the receiver battery on the Telemetry Screen.Release Setting: Determines how quickly the Brake moves from Neutral to the percentage value determined by the Stroke setting when the Anti-Lock Braking function is Active.RPM: Revolutions Per Minute.RPM Display Monitor: Displays the current RPM on the Telemetry Screen from the RPM Sensor in graphical format.Servo Monitor Display: Displays the output levels of the four different channels in bar graph form, allowing you to monitor servo operation in a virtual manner. Servo Reversing: Used to electronically switch the direction of servo travel. For example, if you move the steering wheel to the right, and the steering servo moves to the left, you can use the Servo Reversing function to make the steering servo move to the left. Servo Speed: Used to slow down the transit speed of the servos. Servo transit speed can be slowed in both the Forward and the Return to Center directions.SHR Servo Operating Mode: Using this setting with Digital servos will increase the servo's response time, even above the manufacturer's stated specification. Do not use with Analog servos!SSR Servo Operating Mode: If you're using Airtronics SRG Digital servos, you can use the SSR setting for the fastest response time. This results in the ultimate feel and response, making you feel more in control of your model than ever. Use only with Airtronics SRG Digital servos!Steering Program Indicator: Indicates on the LCD Screen up to four different programming options that are currently programmed to the Steering channel. The Steering Program Indicator will only be displayed if a Steering channel Programming Value is programmed.Steering Trim Display: Displays the current position of the Steering Trim Switch on the Top Screen.Steering Wheel: Proportionally operates the model's right and left steering control. The Steering Wheel features a foam grip for increased comfort, control and feel. In addition, the Steering Wheel spring tension and travel limits can be adjusted.Steering Wheel Tension Adjustment Screw: Used to adjust the spring tension of the steering wheel to best suit the feel of the user.Step Auxiliary: Allows you to program the Auxiliary 1 servo or Auxiliary 2 servo to move a defined amount when toggled ON and OFF using a Push-Button Switch.REFERENCEMT-4S User's Guide.indd 75 2015/10/27 14:39:20
7690478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDETRTRTRStep Value: A preset amount that the servo will travel when a Trim Switch is pressed once. The step value can be adjusted so that the servo either moves more or moves less when the Trim Switch is pressed.Stroke: Determines the amount of Brake that's applied automatically when the Anti-Lock Braking function Activates. Sub-Trim: Used to correct the Neutral Trim setting for the servos, making it possible to center the Trim switches while ensuring the servo horns remain centered. Suppression Capacitor: Primarily used on brushed electric motors, a suppression capacitor helps eliminate electrical noise that could interfere with the operation of your radio control system.Tandem Steering: Used with Four Wheel Steering, the front wheels pivot opposite to the rear wheels.Telemetry: A connection between the receiver and the transmitter that transfers Sensor data from the receiver to the transmitter that can be viewed in real-time on the Telemetry Screen. Data such as Temperature, Receiver Voltage and RPM or Speed can be viewed.Telemetry Signal Indicator: Indicates the current signal strength of the Telemetry connection between the transmitter and receiver. The Telemetry Signal Indicator will only be displayed when the receiver is turned ON and there is a Telemetry connection Active.Temperature Alert Alarm: The Temperature Alert alarm will sound when the TEMP1 and/or TEMP2 temperature reaches the Alert Temperature value programmed in the SYSTEM - TELEMETRY menu. To clear this alarm, press the BACK/CANCEL key or the Push-Button Rotary Dial.Temperature Display Monitor: Displays the current TEMP1 and TEMP2 temperatures in bar graph format on the Telemetry Screen.Throttle Mode Indicator: Indicates the current Throttle Mode type on the Top Screen.Throttle Offset: Allows you to shift the Neutral position of the throttle servo, either toward the High Side or the Brake Side. When used in conjunction with a Push-Button Switch, this function can be used several different ways. For example, if you're driving a glow- or gas-powered model, you can program the Throttle Offset function to shut down your engine with the press of a button. In addition, you can program the Throttle Offset function to increase to a steady idle while you're refueling during a race.Throttle Offset Indicator: Indicates that the Throttle Offset function is programmed. The Throttle Offset Indicator will only be displayed if a Throttle Offset percentage value is programmed.Throttle Program Indicator: Indicates on the LCD Screen up to four different programming options that are currently programmed to the Throttle channel. The Throttle Program Indicator will only be displayed if a Throttle channel Programming Value is programmed. Throttle Trigger: Controls the speed of the model, both forward and backward, or the model's brake. The Throttle Trigger position, angle and spring tension can all be adjusted.Throttle Trigger Position Adjustment Indicator: Indicates the current position of the Throttle Trigger. As the throttle trigger position is adjusted forward or backward, the Throttle Trigger Position Adjustment Indicator will move forward or backward.Throttle Trigger Position Adjustment Screw: Used to adjust the position of the Throttle Trigger either forward or backward.Throttle Trigger Tension Adjustment Screw: Used to adjust the spring tension of the throttle trigger to best suit the feel of the user. Turning the Throttle Trigger Tension Adjustment Screw clockwise increases throttle trigger tension and turning the Throttle Trigger Tension Adjustment Screw counter-clockwise decreases throttle trigger tension. Throttle Trim Display: Displays the current position of the Throttle Trim Switch on the Top Screen.Timer Display: Displays the time of the currently selected Timer on the Top Screen.Timer Type Indicator: Indicates the current Timer Type selected, either LAP or INT (Interval) on the Top Screen.Trim Step Resolution: Used to adjust how far the servos travel when the Trim Switches are pressed. You can increase the resolution, so that the servos travel less when you press the Trim Switches. This makes it possible to fine-tune the settings extremely accurately. In addition, you could decrease the resolution, so that the servos travel more when you press the Trim Switches. This setting may not be as accurate, although you can set large amounts of Trim faster.Trim Switch: The transmitter features four separate Trim Switches positioned around the steering wheel (Trm1, Trm2, Trm3 and Trm4). Each Trim Switch is programmable and will perform a different function depending on what function is assigned to it. For example, Trm1 and Trm2 can be used to adjust steering and throttle Trim and Trm4 and Trm5 can be used to adjust Dual Rate and steering EPA.Variable Rate Adjustment: The Variable Rate Adjustment function allows you to recalibrate the operation of the Steering, Throttle and Auxiliary Lever End Points and Neutral positions to ensure precise control operation. Voltage Alert Alarm: The Voltage Alert alarm will sound when the receiver battery in your model reaches the Alert Voltage value you've programmed in the SYSTEM - TELEMETRY menu. To clear this alarm, press the BACK/CANCEL key or the Push-Button Rotary Dial.GLOSSARY OF TERMS REFERENCEMT-4S User's Guide.indd 76 2015/10/27 14:39:20
