Spektrum SPM1014 - Manual (Page 14)

In the unlikely event that the link is lost during use, the receiver will drive the servos to
their fail-safe 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 fail-safe mode
driving the servos to their preset fail-safe position. When the transmitter is turned on,
normal control is resumed.
Note: The fail-safe positions can be checked by turning the power
off on the transmitter. The green LED on the reveiver will go out and
the servo/ESC will be driven to their stored fail-safe positions.
