Fail Safe/Battery Fail Safe Function "F/S; Fail Safe, Battery Fail Safe - FUTABA 4PK-2.4GHZ Instruction Manual

Fail Safe/Battery Fail Safe Function "F/S"

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 "Rx Type"(p.46) is set "FASST-C1" and "Servo Response"(p.46) is "NORMAL", the setting fail safe (F/S) is only
throttle (TH). Other channels are in "OFF" mode.
-The fail safe data is transferred from the transmitter to the receiver 10 seconds after
the transmitter power is turned on and every minute thereafter. Usually the power is
turned on in transmitter and then receiver order. Therefore, data is not transferred for
about 1 minute 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 direction 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 R604FS and other C2 type receiver only function. When the receiver used is the
R603FF/FF C1 type, this function cannot be used because the receiver type is set to
" FASST-C1 " by receiver type setting (p.46).
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 (BATT-F/S)
When the receiver battery voltage drops below a certain value when this function is en-
abled, the throttle servo moves to the position set by fail safe function. When the battery
voltage 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).
-For an R603FS/FF with RX TYPE (page 46) set to C1 types "FASST-C1", when throttle (TH) is set to fail safe (F/S), the
battery fail safe function is executed automatically. It cannot be set at the transmitter.
