imagination.
Fail Safe
The Fail Safe/Hold function is available only when you
use the mx-12 transmitter in PCM modulations. This
function is designed to help minimize damage to your
aircraft during a loss of signal to the receiver. The ser-
vos either assume the fail-safe presets or hold their last
good signal position.
As noted earlier, if you are in the PPM modulation, the
Fail-Safe/Hold function is not applicable. Therefore,
the Fail-Safe/Hold function will not appear on your LCD
screen menu while in the PPM mode. Refer to the Mo-
dulation Selection section for more information pertai-
ning to the broadcast signal of your mx-12 transmitter.
Note: The throttle fail safe position is defaulted to the
idle position for added safety.
