EN Building on the success of the DX3S transmitter, the Spektrum™ DX4S and DSMR™ surface protocol bring you even more features including pre-programmed steering mixes, full switch assignability and a convenient back-lit display. Spektrum™ DSMR technology is an exclusive, frequency-agile 2.4GHz protocol that provides surface RC vehicles and boats with superb range and response. This is particularly true in environments where many other 2.4GHz transmitters are in use at the same time.

EN Installing Optional Li-Po Battery Pack 1 2 Changing the Rubber Grip This transmitter includes 3 sizes of grips. The medium-size grip is installed at the factory. Inside the grip is a letter size: L for large, M for medium and S for small. To change the rubber grip: 1. Lift the edge of the grip and pull the grip away from the handle. 2. Align the tabs on the new grip with the slots in the handle. 3. Press the grip against the handle.
EN WARNING SCREENS Low Battery Alarm An alarm will sound and a warning screen will show when the transmitter’s battery power falls below a set limit. This alarm reminds a user to bring a model under full control, power off the transmitter and replace the batteries. Press the Roller to stop the alarm and go to the Main Screen. Set the low battery limit using the System Screen. CAUTION: If you decide to use the optional Li-Po battery back, never allow the battery voltage to fall below 6.4V.
EN 2. When both directions are selected, move the control (steering or throttle) toward the control direction you wish to change. The selection box moves to the desired direction. You do not need to hold the control in the desired direction. 3. To change the opposite direction, simply move the control in that direction. 4. Press the Rolling Selector to save the selection.
EN Reverse The Reverse function, also known as servo reversing, establishes the channel direction relative to the channel input . Use the reverse menu if, for example, the wheels turn left when you turn the steering wheel to the right. Reverse is available on all channels and is normally the first function you should test and adjust during programming. Travel The Travel function supports precise endpoint adjustments in all channels. Travel values range from 0–150% (Default is 100%).
EN RECEIVER COMPATIBILITY The DX4S transmitter is compatible with Spektrum DSMR, DSM®, DSM2®, and Marine surface receivers. The SR410 DSMR receiver is only compatible with DSMR transmitters. Install the receiver in your vehicle using double-sided foam servo tape. Foam servo tape holds the receiver in place and protects the receiver from vibration. Position the antenna vertically and away from the vehicle in an antenna tube. The SR410 has a coax style antenna.
EN Failsafe The throttle failsafe position is set during binding. In the unlikely event that the radio link is lost during use, the receiver will drive the the throttle servo to its pre-programmed failsafe position (normally full brakes) and all other channels will have no servo output. If the receiver is turned on prior to turning on the transmitter, the receiver will enter the failsafe mode, driving the the throttle servo to its preset failsafe position.
EN Timer The transmitter Timer can function as either an Up or Down Timer. Down Timer (default selection) The Down Timer allows you to adjust the amount of time in 10 second increments to a maximum of 21 minutes, which will then start a countdown to “0” once activated. The Down Timer value is normally the length of a race or vehicle runtime. The Down Timer can be reset by selecting Timer Reset or by holding the switch that is assigned to that timer for 3 seconds.
EN Mixing The DX4S features a Steer Mix, Brake Mix and two programmable mixes (Mix A and Mix B). Steer Mix Use the Steer Mix for vehicles requiring either four-wheel steering (4WS) or dual steering servos (Dual ST). NOTICE: Before driving a model, always do a check of the transmitter’s control of the vehicle with the vehicle’s wheels off the ground. Mix Options 1. Select AX1 or AX2 as the slave channel. Aux1 and Aux2 can only be assigned to one mix at a time.
EN Programmable Mix The programmable mixes enable you to assign any channel as a Master or Slave, which is particularly helpful when you need to assign an Aux channel as a Master. 1. Scroll to Inh. Press the rolling selector once and select a Master channel. 2. Select a Slave channel. 3. Adjust the A Value percentage. You can assign custom names to Mix A and Mix B, making it easier to remember what each mix does. Assign the names the same way you would for the Username or Model Name.
EN Throttle Punch The Throttle Punch function is used to offset the throttle to a preprogrammed position and activate when 4% of throttle travel is applied. Throttle punch is typically used in nitro vehicles to reduce the lag due to throttle linkage slack. To Access the Throttle Punch Function: • In the List screen, use the Rolling Selector to highlight the Th Punch function. • Press the Rolling Selector to access the Throttle Punch function. The above screen will appear.
EN System The System function lets you adjust transmitter functions. List Two modes are available: Expert and Standard. The DX4s defaults to Expert where all of the programming menus are available. Standard mode eliminates the expert screens and functions from the list; making it ideal for basic models. Display Contrast The contrast function provides adjustment to the brightness ratio of the lightest to the darkest part of the screen.
EN Telemetry The Telemetry setting function is used to select a default screen for display, including Main, Telemetry or Roll. It is also used to access the Telemetry SPEED, BATTERY and TEMPERATURE sensor settings. To Access the Telemetry Setting function: In the List screen, use the Rolling Selector to highlight Telemetry, then press the Rolling Selector. The TELEMETRY screen will appear.
EN TROUBLESHOOTING GUIDE Problem The system will not connect Possible Cause Solution Transmitter and receiver too near each other Move transmitter 8 to 12 feet (2.4 to 3.6m) from receiver Transmitter and receiver too near large metal objects (vehicles, etc.) Move away from large metal objects (vehicles, etc.
