Fail Safe/Battery Fail Safe Function "F/S"
Fail Safe/Battery Fail Safe Function "F/S" (All channel)
Fail Safe Mode (F/S)
This function moves each servo to a preset position when the receiver cannot receive the
signals from the transmitter for some reason.
-When the condition set at "FH" is Rx type (P42), 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 was turned on.
The data is transferred every 5 seconds after that. Be careful because normally the transmitter power is turned on first and the
receiver 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 receiver in its position immediately before reception was lost. It
is an R2104GF and other S-FHSS type receiver only function. When the receiver used
is the R603GF/R2004GF FHSS type, this function cannot be used because the receiver
type is set to "FH" by receiver type setting (p.42).
Off mode (OFF)
This function stops output of signals to the servos and places the servos into the free
state when the receiver cannot receive.
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 R2104FG and other S-FHSS types only. It cannot be used with the R603GF and R2004FG FHSS
type.
Refer to P44 and display the channel menus to be set. For steering and throttle display
the STEERING 2 screen and THROTTLE 2 screen by (UP) or (DN) button.
