Failsafe
The throttle failsafe position is set during binding. In the unlikely event that the radio link is lost
during use, the receiver will drive the the throttle servo to its pre-programmed failsafe position
(normally full brakes) and all other channels will have no servo output. 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 the 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.
The Bind Screen shows the active model and supports binding the active model memory to a
receiver.
Bind
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 (see ModelMatch for more information).

IMPORTANT:
If you adjust the steering and throttle trim on your transmitter, the receiver must be turned off and back on again in
order to save the new trim settings. Otherwise, AVC will not function properly.
