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 receiver features 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.
Standard Mode
If loss of signal occurs,
SmartSafe™ technology
moves the throttle channel to its
designated failsafe position (low
throttle) that was set during binding.
All other channels hold their last
position.When the receiver detects
signal from the transmitter, normal
operation resumes.
Gas Mode
Preset failsafe is ideal for most
nitro/gas vehicles. With preset
failsafe, all channels go to their
preset failsafe positions if the
signal is lost, preventing an
out of control situation. When
the receiver detects signal
from the transmitter, normal
operation resumes.
Gas Mode
1 Push and Hold Bind Button
2Power on Reciever, keep Bind button depressed until
binding is complete
3 Place transmitter in Bind Mode and finish Binding

Standard Mode
1 Push and Hold Bind Button
2 Power on Reciever
3Release Button after RX goes into Bind Mode (flashing LED)
4 Place transmitter in Bind Mode and finish Binding
FAILSAFE
Failsafe position is set during binding. In the unlikely event
that the radio link is lost during use, the receiver will drive all
channels to its pre-programmed failsafe position.
Bind Button
Active portion

Antenna Tube Not
Included. Tube size
may vary, test for
proper fit.
BINDING
The SR315 receivers must
be bound to the transmitter
before they will operate.
Binding is the process
of teaching the receiver
the specific code of the
transmitter so it will only
connect to that specific
transmitter.
RECEIVER COMPATIBILITY
The SR315 receiver is compatible with
Spektrum DSM2®and DSMR®radio
control surface systems. Install the
receiver in the position recommended by
the vehicle’s manufacturer. Double-sided
tape or foam may be used to secure the
receiver in place.
The case of the receiver can accept an antenna tube directly, making
optimal antenna placement easy (antenna tube not included).

RATES
EXPONENTIAL
TIMER
Rates allow the driver to reduce the travel (0-100%) of the Steering, Throttle, or Braking with a trimmer
button. The Override option allows drivers to select a different rate value (0-125%) while holding down the
assigned trimmer button. This is especially helpful for oval racers that program minimal steering throw to
desensitize steering during racing, but requires maximum steering angle to drive out of a crash or get turned
around on the track.
To adjust Rate values:
1. Slide to Steering and press OK to select between Steering, Throttle or Brake.
2. Slide Up or Down to adjust the Rate value. Press OK to save the selection.
3. Set the Switch setting to On to enable Rates, select Inh to disable Rates.
4. Select an Override rate and switch.
5. Select the OTF (On-The-Fly) trimmer that will be used to adjust Rates On-The-Fly.
TIP: In order for the OVERRIDE to operate, you must assign it to a switch or trimmer. The default position
for this function is inhibited.
The Exponential (Expo) function affects the response rate of the steering, throttle and/or brake. A positive
Steering Expo value, for example, decreases steering sensitivity around neutral to make it easier to drive at
high speeds in a straight line while still allowing for maximum turning radius. While sensitivity with positive
Expo is decreased around neutral, it increases the sensitivity near the end of travel.
To adjust Expo values:
1. Select Throttle or Steering.
2. Slide Up or Down to adjust the Rate value.
3. Press OK to save the selection.
4. Select an OTF switch to activate Exponential.
IMPORTANT: Both positive and negative Expo values are available. A positive Expo value results in the
center being less sensitive (desirable most of the time), while a negative value increases the sensitivity
around center (normally not used).
The DX6C Timer function allows you to program a countdown timer and stop watch (count up timer) to display on the main screen.
An alarm sounds when the programmed time is reached. You can program the timer to start using the assigned switch position or
automatically when the throttle moves above a pre-programmed position.

Binding
Binding is the Process of teaching the receiver the specific transmitter’s code called GUID (Globally Unique
Identifier) and storing failsafe values. When a receiver is bound to a transmitter/model memory, the receiver will
only respond to that specific transmitter/model memory.
Bind Process
1. Use a bind plug or press the bind button to place the receiver into Bind mode. The LED on the receiver
will begin to flash.
2. Power on the transmitter.
3. Select the Model Memory you wish to bind to.
4. Select Bind from the List menu.
5. Move the throttle channel to the desired failsafe position.
NOTICE: The throttle channel must stay in the failsafe position until binding is complete.
6. Slide to Bind and press OK. The orange LED flashes on top of the transmitter.
7. When the bind process is complete, the transmitter and receiver LEDs stop flashing and turn solid
orange.
8. Remove the bind plug from the receiver and keep it in a convenient place.
IMPORTANT: Always remove the bind plug from the receiver when the bind Process is complete. Failure to
do so will cause the receiver to enter bind mode the next time you power on the receiver.
Failsafe
In the unlikely event that the radio link is lost during use, the receiver will drive the throttle servo to its pre-programmed failsafe posi-
tion (normally full brakes) and all other channels will have no servo output. The throttle failsafe position is set during binding. If the
receiver is turned on prior to turning on the transmitter, the receiver will enter the failsafe mode, driving the throttle servo to its preset
failsafe position. When the transmitter is turned 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.
BIND/FRAME MENU
For compatibility with all types of servos, three frame rates are available:
• 11ms: Offers good response rates and is compatible with most digital and analog servos (this is the
default position). Works with DSMR®surface receivers.
• 16.5ms: Needed for older analog servos. Works with DSM2®surface receivers.
• 22ms: Needed for older analog servos. Works with DSMR receivers.
TIP: You should always use the fastest response rate the servos can handle. This gives the lowest latency
and fastest response. If the frame rate is incompatible with the servo, the servo will move erratically or, in
some cases, not at all. If this occurs, change the frame rate to the next highest value.
IMPORTANT: Always rebind after changing the Frame Rate.
NOTICE: AVC receivers must be calibrated after binding for proper operation.
