4. Hold down on the SCROLL and CHANNEL buttons while turning on the transmitter.
To enter System Mode, press the SCROLL button until “BND” appears on the screen.
5. With the steering wheel and the throttle trigger in their desired failsafe positions, press
the INCREASE and DECREASE buttons at the same time to enter bind mode. “BND”
will flash when in bind mode.
6. After several seconds the LED on the receiver will quit flashing and remain solid,
indicating that the binding process was successful. Once binding is complete, the
system will automatically connect.
7. Once the bind process is complete and before power is cycled on the receiver, remove
the bind plug from the receiver and store it in a convenient place. Failure to remove the
bind plug will result in the receiver going back into bind mode.
Antenna
During the first installation, the receiver(s) must be bound to the transmitter. Binding is
necessary to program the receiver(s) to distinguish its corresponding transmitter from
others. Also failsafe positions are transferred from the transmitter to the receiver during
binding. (See binding below for more details.)
It is necessary to bind the receiver to the transmitter during the first installation, and is
recommended when the receiver is moved from one vehicle to another. Receivers can be
re-bound to the same transmitter or to other transmitters an infinite number of times. Also
multiple receivers can be bound to a single transmitter, which is common when using one
transmitter to operate several models.
Only bound receivers and transmitters can connect. During power-up, the transmitter
scans for a free channel while the receiver scans for its bound transmitter. When control is
achieved, the LED on the receiver remains on continuously.
In the unlikely event that the link is lost during use, the receiver will drive the servos to
their failsafe positions that were preset during the binding process. If the receiver is turned
on prior to turning on the transmitter, the receiver will enter the failsafe mode, driving the
servos to their preset failsafe position. When the transmitter is turned on, normal control is
resumed.
To Bind the Receiver to the Transmitter
1. Make sure the transmitter and receiver are turned off.
2. With the receiver off, insert the bind plug into the BIND port on the receiver.
3. Power the receiver through any port. The green LED will flash continuously, indicating
the receiver is in bind mode.
Binding
At 3.6 inches in length, the receiver antenna is significantly shorter than conventional
antennas. Like all antennas, it’s important to mount the antenna vertically. In most cases the
antenna can be mounted inside the body with no loss of range. Mount the receiver antenna
as recommended by the manufacturer of the vehicle, however, it may be necessary to trim the
plastic antenna tube (included with your vehicle).

The DSM ® system operates in the 2.4GHz band (that’s 2400MHz). This high frequency offers
a significant advantage as it’s well out of the range of model-generated radio interference
(like motor and ESC noise). All the complex issues that now exist using 27 and 75MHz
radios with model-generated interfering noise are eliminated with this system. The DSM
system uses Direct Sequencing Spread Spectrum modulation to generate a wide signal on a
single frequency. The FCC requires that these systems be “smart”– incorporating collision
avoidance such that when a system is turned on, it scans the 2.4GHz band and selects a
channel that is not being used, then begins transmitting on that unused channel. 79 channels
are available and the odds of one DSS spread spectrum system interfering with another are
astronomically remote.
