Mixing Operation and Switches

their corresponding positions.

1. Press the Select key until offset is highlighted. The
display will show the current mixing channels at the
top of the LCD, with the word "OFFSET" in the
center of the LCD. The value to the right is the
mixing Offset neutral point, currently 0.

With a little practice, programmable mixing will become
easier to understand. Mixing is only limited by your
imagination.
Fail Safe
The Fail Safe 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 servos 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 Function is not applicable. Therefore, the Fail
Safe Function will not appear on your LCD screen menu
while in the PPM mode. Refer to the Modulation Selec-
tion section for more information pertaining to the
broadcast signal of you mx-12 transmitter.
Note: The throttle Fail Safe position is defaulted to the
idle position for added safety.
