XP70 Instruction Manual
The Fail-Safe/Hold Function is available only when you
use PCM modulations (see Modulation Page 0). During
loss of signal, this function drives the servos to either the
fail-safe preset positions or holds the last signal position.
As noted, 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 in PPM
mode. Refer to the Modulation Selection Section for more
information.

fail-safe (
F.S.
) (the servo goes to a preset programmed
position during signal loss) or
HOLD
(the servo holds last
position during signal loss).
Adjust each channel by selecting the channel desired with
the
Select
key. With the stick/switch in the desired fail-
safe position, press the
clear
key to store these fail-safe
positions in memory.
NOTE
: To test the fail-safe, turn the transmitter off.
Any channel set to a fail-safe position should drive
to that position, and any servo set to hold should
remain in its last good position.
NOTE
: The factory default settings for the Fail-Safe
function have the Throttle channel set to Fail-Safe
-170 (Low Throttle) and all other channels are set to
hold the last good signal.
