4. Press and hold the bind button on the module while turning on the power
switch. the bind button will flash and within a few seconds the system will 
connect. the LEDs on the receivers will go solid, indicating the system has 
connected. 
note: You must remove backplate to access the bind/range button.
5. Remove the bind plug and store it in a convenient place.
6. After you’ve programmed your model, it’s important to rebind the system so 
the true low throttle and neutral control surface positions are programmed.
•
Before Binding All Servo Outputs Must be Assigned
In the Servo Menu under Assignment all channels that you wish to use must
be assigned before binding. this will place the transmitter in PPM/9, PPM/12 
mode etc. If the number of channels being used is ever changed the system 
must be rebound.
•
+ Positive Shift Must be Selected
In the Memory menu under Properties, + (plus) must be selected in the Shift
column
• The system Must be in FM/PPM mode
 this occurs automatically when the Spektrum module is plugged in. to confirm 
press the up or Down arrows to access the Modulation screen. FM/ PPM 
Should be displayed.
Software Versions Supported: 
V1.x

Binding
All of Spektrum’s aircraft receivers feature a unique SmartSafe
™
failsafe system,
while the AR12000 features two types of failsafe programming: SmartSafe and 
Preset Failsafe.
SmartSafe
SmartSafe is automatically selected during the standard binding procedure and is 
ideal for electric aircraft as well as most gas- and glow-powered aircraft. 
How SmartSafe Works
When the Receiver is Powered On without a Transmitter Signal
If you turn on the AR12000 before you turn on the transmitter, SmartSafe 
prevents the throttle from functioning and drives all other channels to their preset 
positions.
When there is a Loss of Signal in Flight 
If the receiver loses the transmitter’s signal in flight, or any other time after a 
successful connection has been made, SmartSafe sets the throttle to the position 
it was in during the binding process. All other channels hold the positions they 
were in at signal loss.
Preset Failsafe
Preset Failsafe allows you to set the specific control positions for all channels 
to go to should you encounter signal loss in flight or at any other time after a 
successful connection has been made. Preset Failsafe is typically used to prevent 
“fly aways” in high-performance models by deploying spoilers in sailplanes or 
putting gas- and glow-powered models into a slight turn at reduced throttle.
Programming SmartSafe
(All Spektrum Aircraft Receivers)
During the binding process, the bind plug is left in throughout the 
process and is removed only after the receiver connects to the transmitter. After 
the connection is made, confirmed by operating the servos, the bind plug can be 
removed. the receiver is now programmed for SmartSafe.
Programming Preset Failsafe
(AR12000, AR12100, AR9300, AR9200, AR9100, AR9000 and 
AR7100/R SPM Receivers Only) 
During the binding process the bind plug is inserted in the bind port or in the 
charge jack, then the receiver is powered up. the LEDs in each receiver should 
blink, indicating that the receiver is in bind mode.
Now before binding the
receiver to the transmitter and with the receiver in bind mode, remove
the bind plug. the LEDs will still be blinking. With the control sticks and 
switches in the desired failsafe positions, bind the transmitter to the receiver by 
pressing and holding the bind buttons on the back of the transmitter/module and 
turning on the transmitter. the system should connect in less than 15 seconds. 
the receiver is now programmed for preset failsafe. 
note: Failsafe positions are stored via the stick and
switch positions on the transmitter during binding.
