About the Radio

The Losi DSM radio installed in the Limited Edition Aftershock is a state of the art system featuring the latest technology
that requires no crystals. This system includes all the features you may find useful. Be sure to read through the Radio
operation instructions on what and how to use these features. The following is a simple guide to items and functions
commonly referred to.
1. Steering Wheel - Controls the truck's direction (left/right).
2. Throttle Trigger – Controls the speed and braking (pull for throttle and push forward for brakes).
3. Throttle Trim (TH.TRIM) - Allows you to set the idle/brake of the truck.
4. Steering Trim (ST.TRIM) – Adjusts the "hands off" direction of the truck.
5. Transmitter Antenna - Transmits signal to the receiver in the truck.
6. Servo Reversing Switches – Changes the direction of servo operation.
7. Power & Signal Indicators (LEDs)
Red (left) indicates signal strength
Green (right) indicates battery power
8. Power Switch - Turns your transmitter ON and OFF.
9. Steering Rate (ST.D/R) – Adjusts how much the wheels turn when steering wheel is turned right/left.
10. Endpoint Adjustment Pots – Allow you to adjust the maximum movement of the servos.

Re-Binding the Transmitter to the Receiver
®
The Losi DSM radio system included in the Limited Edition Aftershock operates on 2.4GHz and provides 79 different
"channels", which are automatically selected when the transmitter and vehicle are turned on. The communication between
the transmitter and receiver begins in the few seconds after the transmitter and vehicle are both turned on. This is called
the binding process. The Losi DSM radio system will not interfere with previous technology radio systems that operate on
27MHz or 75MHz frequencies, and you will not receive any interference from them. Although set at the factory, below are
the steps required to re-bind your transmitter to the receiver should the need arise. During the binding process there is a
unique ID from the transmitter communicated to the receiver to ensure trouble-free radio operation.

Steps to Re-Bind
1. Ensure that the transmitter and vehicle are both turned off.
2. Using the supplied Bind plug (which looks like a standard receiver plug with a wire loop installed). Insert the Bind
plug into the receiver slot labeled "BIND". Looking down on the receiver this slot would be below the LED and is the
farthest from the LED, or nearest to the corner of the receiver.
Note: You do not need to remove any of the other plugs to re-bind.
3. With the Bind plug installed, turn on the vehicle. Notice a blinking Green LED within the receiver.
4. Now you are ready to turn on the transmitter. You should notice on the back of the transmitter a similar blinking
Orange LED under the translucent cover.
5. Both the receiver and transmitter blinking Green LEDs will stop blinking and become solid, indicating they have
"bound" themselves together.
6. Turn off both the vehicle and the transmitter then remove the Bind plug from the receiver. Failing to remove the Bind
plug will cause the receiver to attempt to re-bind every time you turn on the vehicle and transmitter.
7. Turn on both the vehicle and transmitter to ensure operation. If the transmitter does not control the vehicle, please
repeat steps 1–6. Should this not correct the problem please call Horizon Service/Repair for further assistance.
8. The Bind process is complete. Your vehicle's radio system should be ready for use.
Using the EPA Adjustment
The Endpoint Adjustment (EPA) feature of the Losi DSM radio allows you to set the amount the servo travels when you
turn the steering wheel or push/pull the throttle. This is especially helpful to prevent the servos from stalling with normal
11
operation.
Steering: First set the steering trim so the truck goes straight without touching the steering wheel. Lift the front
of the truck off of the ground and turn the steering wheel to the right. Use the included mini screwdriver
to adjust the pot marked "right" back and forth stopping when the wheels can turn to the right no more.
Repeat this procedure turning left using the pot marked "left".
Throttle: First set your Throttle/Brake trim. With the engine not running,
remove the air cleaner. Pull full back on the throttle trigger
and note the position of the carburetor barrel. Adjust the
pot marked "throttle" back and forth so that the barrel just
reaches wide open (going further will only hurt performance).
Brake: Release the trigger and push it forward. Turn the pot marked
"brake" counterclockwise (away from the "+") as far as it
will go. Now turn it clockwise (toward the "+") until it stops
moving. This will give you maximum push brake.
