Fail-Safe/ Battery Fail-Safe Function - FUTABA 7PX User Manual

This function sets the servo operation position when transmitter signals cannot be received
by the receiver for some reason or the battery voltage has dropped.
-Fail safe mode
This function moves each servo to a preset position when the receiver cannot receive the
signals from the transmitter for some reason.
* 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 10 seconds after that. Be careful because normally the transmitter power is turned on fi rst and
the receiver power is turned on next and there is no data transfer for about 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 di-
rection in which the brakes are applied.
Hold mode
-
This function holds the receiver in its position immediately before reception was lost.
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 transmit-
ter can be received again
Battery fail safe function (B-F/S)
-
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 voltage
recovers, the battery fail safe function is automatically reset.
* This function cannot be used when the channel is not set to fail safe.
* When the receiver setting (page 37) is "FASST", only CH2 (throttle) can use this function.
