MODE
The settings of the options "MODE", "F.S.Pos." and "DELAY deter-
mine the response of the receiver when there is an interruption in
transmission from the transmitter to receiver.
The setting programmed under "MODE" always refers to the channel
set in the line OUTPUT CH.
The factory setting for all servos is "HOLD".
Each selected OUTPUT CH (servo connector of the receiver) can be
set to:
• FAI(L) SAFE
With this selection, the corresponding servo moves into the posi-
tion displayed in µs in the line "POSITION" in case of a malfunc-
tion after expiration of the delay set in the "DELAY" line for the
remainder of the malfunction.
• HOLD
With the "HOLD" setting, over the course of a malfunction, the
servo remains in the last correctly received servo position.
• OFF
With the "OFF" setting, over the course of a malfunction, the
receiver stops transmitting (buffered) control pulses for the rel-
evant servo output The receiver switches off of the pulse line in
a manner of speaking.
Attention
Analogue servos and many digital servos no longer experience
resistance to the ongoing control pressure after control pulses
stop and are moved out of their position at higher or lower
speed.
F.S.POS.
For each OUTPUT CH (receiver servo connection), set the servo posi-
tion for the servo to assume in a malfunction in "FAI(L) SAFE" in the
line "F.S.POS." by using the + or – buttons.
The setting is carried out in steps of 10 μs as described below under
"Programming step-by-step" under OUTPUT CH.
Factory setting: 1500 μ s (servo center).
‖ In all three modes "OFF", "HOLD" and "FAI(L) SAFE", the function
"F.S.POS." is particularly important when waiting for a valid sig-
nal after turning on the receiver:
The servo immediately moves into the fail safe positions set in the
"POSITION" line. This prevents landing gear from retracting when
the receiver is accidentally turned on while the transmitter is off.
