5. Remove the bind plug from the BIND/DATA port on the receiver before you power off the
transmitter and store it in a convenient place.
6. After you’ve set up your model, it’s important to rebind the system so the true low throttle and
neutral control surface positions are set.
IMPORTANT: Remove the bind plug to prevent the system from entering bind mode the next time the
power is turned on.
AR6115/AR6115e Failsafe
•Preventsunintentionalelectricmotorresponseonstart-up.
•Establisheslow-throttlefailsafeiftheRFsignalislost.
• The AR6115(e) removes servo output pulses to all channels except the throttle channel during
failsafe.
•TheAR6115(e) throttle failsafe position is stored via the throttle stick position on the transmitter
during binding.
HOW AR6115/AR6115e FAILSAFE WORKS
Receiver Power Only

Plugging in the Leads
Plug the servo leads into the appropriate servo ports in the receiver noting the polarity of the
servo connector.
Red LED Hold Indicator
The AR6115/AR6115e features a red LED that indicates the number of holds that have occurred since
the receiver was last powered on. The LED will flash the number of holds then pause (e.g., flash,
flash, flash, pause, flash, flash, flash, pause indicates three holds occurred since the receiver was last
turned on). Note that holds are reset to zero when the receiver is turned off. During the first flights of a
new airplane, it’s recommended to check the red LED hold indicator. If it’s flashing, it’s important to
optimize the installation (move or reposition antennas) until no hold occurs. On later flights, the LED
Hold Indicator can be used to confirm RF link performance.
Range Testing
Before each flying session and especially with a new model, it is important to perform a range check.
All Spektrum aircraft transmitters incorporate a range testing system which, when activated, reduces
the output power, allowing a range check.
1. With the model restrained on the ground, stand 30 paces (approx. 90 feet/28 meters) away
from the model.
