• All channels have no output until the receiver has linked to the transmitter. Initial Setup Verify your transmitter is updated to the latest Spektrum AirWare™ software to take advantage of Forward Programming. See your transmitter manual for updating instructions.
AR637T Receiver- Basic AS3X Setup To use AS3X technology with the Spektrum AR637T Receiver, the receiver needs to be set up with a compatible Spektrum transmitter. Verify the basic setup and trim is accurate before attempting AS3X setup. Forward Programming Setup: The receiver is directly configured through the Forward Programming menu.
AS3X Reaction Test This test ensures that the AS3X control system is functioning properly. Assemble the aircraft, bind your transmitter to the receiver, and complete the AS3X First Time Setup in the Forward Programming menu before performing this test. Raise the throttle above 25% to activate AS3X, then lower the throttle. Once the AS3X system is active, control surfaces move in respose to aircraft movement.
AR637T Receiver- SAFE Setup Setting up SAFE Technology on the AR637T Receiver takes place in Forward Programming. Complete the AS3X setup and verify operation in flight. Forward Programming Setup: To add SAFE flight stabilization the Flight Modes on the receiver need to be configured. 1.

If your system displays a hold, diagnose the cause and resolve the issue before flying again. It is normal to see a hold logged if you power OFF your transmitter and back IMPORTANT: The Spektrum Flight Log (SPM9540) is not compatible with the AR637T receiver.
Range Testing Before each flying session, and especially with a new model, it’s important to perform a range check. All Spektrum aircraft transmitters incorporate a range testing system, which reduces the output power to allow a range check. 1. With the model resting on the ground, stand approximately 100 feet (30 meters) away from the model.
Receiver Power System Requirements Some of the power system components that affect the power supply to the receiver include: • Receiver battery pack (number of cells, capacity, cell type, state of charge). • The ESC’s capability to deliver adequate voltage to the receiver when the servos demand high current •...
