Fun ction
Fail Safe Function "FAIL SAFE"
Fail Safe Function "FAIL SAFE"
(All channel)
Fail Safe Mode (F/S)
This function moves each servo to a preset position when the receiver does not receive a
clear signal from the transmitter.
-When the condition set at "FHSS" is Rx type, fail safe (F/S) can be set only for throttle (TH). Other channels are set to the
normal mode.
-The fail safe data is transferred from the transmitter to the receiver 10 seconds after the transmitter power is turned on. The
data is transferred every 5 seconds after that. Be careful because normally the transmitter power is turned on rst and the re-
ceiver power is turned on next and the data is transferred for approximately 10 seconds after the receiver power is turned on.
-For gasoline engine cars, for safety we recommend that this fail safe function be used to set the throttle channel in the direc-
tion in which the brakes are applied.
Hold mode (HOLD)
This function holds the servo/s at the position they were in immediately before recep-
tion was lost. This applies to the T-FHSS type (R304SB...,etc.) and the S-FHSS type
(R2104GF...,etc.) receivers only. When the receiver used is an R603GF/2004GF or other
FHSS type, this function is not available.
Off mode (OFF)
In this model the receiver stops outputting a signal to the servos if the transmitter signal
is lost. The servos become effectively unpowered.
The F/S, HOLD, and OFF modes are automatically reset when signals from the trans
-
mitter can be received again.
Battery fail safe function (BFS)
If the receiver battery voltage drops below a certain value when this function is enabled,
the throttle servo moves to the position set by fail safe function. When the battery volt
-
age recovers, the battery fail safe function is automatically reset.
-This function cannot be used when the throttle (TH) is not set to fail safe (F/S).
-This function is for the T-FHSS type (R304SB...,etc.) and the S-FHSS type (R2104GF...,etc.) receiver only. It cannot be used
with the R603GF and R2004FG and other FHSS type.
