Binding
Binding is the process of programming the receiver to
recognize the GUID (Globally Unique Identifier) code of a single
specific transmitter. The DX3™ transmitter and SR315 receiver
are bound at the factory. If you need to rebind, follow the
instructions below.
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 the transmitter to a different receiver.
Hold the steering wheel and throttle trigger in the desired failsafe
positions during binding. In the unlikely event that the radio
link is lost during use, the receiver will drive all channels to its
programmed failsafe position.
If using a SMART ESC and SMART battery, the transmitter
SMART Battery Level indicator will show the vehicle battery
level within 10 seconds of powering on and connecting.
Motor Care
• Prolong motor life by preventing overheating conditions.
Undue motor wear results from frequent turns, stops
and starts, pushing objects, boating in rough water or
vegetation and boating continuously at high speed.
• Over-temperature protection is installed on the ESC to
prevent circuit damage, but cannot protect the motor
from pushing against heavy resistance.
• Lubrication is important to prevent motor damage. If your
motor gets wet, lubricate the busings supporting the motor
shaft with light duty machine oil. Failure to do so can cause
the motor shaft to seize against the motor bushings.
CAUTION:
Do not touch the motor until it has had time
to cool. It can become extremely hot when in use.
Radio and ECS Setup
The electronics installed in the Impulse 32 are fully configured and ready for operation out of the box. See the following
instructions for proper binding and failsafe setup and ESC calibration.

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.
2. Set the trims and control positions at the desired failsafe
settings, press and hold the bind button, and power ON the
DX3 Smart transmitter.
3. When the orange LED on the DX3 Smart transmitter remains
lit, it is connected to SR315 receiver.
