WARNING:
Do not kink, cut or damage the antenna wire. The antenna is made of a coaxial wire; if the outer
sheath becomes damaged, the receiver will not work properly. If the antenna is damaged in any
way, replace the antenna before attempting to use the receiver.

Receiver Antenna
The SR315 receivers feature a coaxial antenna design for easy installation in almost any model. Think of the last 1
inch (32mm) on the tip of the antenna as the active portion of the antenna, the coaxial portion leading up to it is just
an extension. Install the antenna so the active portion is positioned as high as possible in the vehicle, and not “in the
shadow” of any carbon fiber or metal. The case of the receiver can accept an antenna tube directly, making optimal
antenna placement easy (antenna tube not included).
Binding to SLT
Binding is the process of programming the receiver to
recognize the GUID (Globally Unique Identifier) code of a
single specific transmitter.
Binding Procedure
1. Power ON the receiver, press the bind button three
times quickly (within 1.5 seconds of the fi rst button
press). The LED will begin to fl ash with a pause.
2. Set the trims and control positions at the desired fail-
safe settings, and power ON the SLT3 transmitter.
3. When the LED on the SLT3 transmitter and receiver
remain lit, binding is complete.
You must rebind when:
• Different failsafe positions are desired e.g., when
throttle or steering reversing has been changed.
• Binding the receiver to a different transmitter.
Binding to DSMR/DSM2
Binding Procedure
1. Push and Hold Bind Button
2. Power on Reciever
3. Release Button after RX goes into Bind Mode (fl ashing
LED)
4. Place transmitter in Bind Mode and fi nish Binding.
Failsafe
In the unlikely event that the radio connection is lost
during use, the receiver will drive the servos to their pre-
programmed failsafe positions as set during Binding.
If the receiver is powered on before powering on the
transmitter, the receiver will enter this failsafe mode.
When the transmitter is powered on, normal control is
resumed.
IMPORTANT
: Failsafe activates only in the event that
signal is lost from the transmitter. Failsafe will NOT
activate in the event that receiver battery power decreases
below the recommended minimums or power to the
receiver is lost.
