FailSafe configuration for fs-th9x + rm-003 + fs-ia10b

[AntonC]

Hello everybody

I use the set which described in topic, and when I switch the radio off all channels don't reset to default (just stay where it was before switching). As I understand the receiver just don't send default PPM signal. Could anybody suggest the solution?

Full set
Fs-th9x (er9x) -> rm-003 -> fs-ia10b -> APM 2.8

What I already tried:
update firmware for APM's ppm decoder (https://www.youtube.com/watch?v=dC5IcCB ... Nemesisdog)
use original radio's firmware and configure failsafe on it
set expected channels position and press "update" on receiver (also I can't find the manual for receiver and really don't understand how to use update button correct)

All this moves didn't help.
