Fail Safe - FUTABA T12K Instruction Manual

FAIL SAFE

The Failsafe function may be used to set up
positions that the servos move to in the case of
radio interference.
You may set either of two positions for each
channel: Hold, where the servo maintains its last
commanded position, or failsafe, where each
servo moves to a predetermined position. You may
choose either mode for each channel.
The T12K system also provides you with an
advanced battery monitoring function that warns
you when the receiver battery has only a little
power remaining. In this case, each servo is
moved to the defined failsafe position. The battery
failsafe may be released by operating a predefined
control on the transmitter (default is throttle),
do not continue to fly, land as soon as possible.
Remember, if the predefined control suddenly
moves to a position you did not command, land at

Fail safe setting procedure
1. Move the cursor to the "F/S" item of the
channel you want to set and push the RTN
button to switch to the data input mode.
2. Select the F/S mode by scrolling the Push
dial. A confirmation message appears.
*The display blinks.
3. Push the RTN button. (Push the S1 button to
stop setting.)
*The channel switches to the F/S mode.
4. Move the cursor to the "POS" item.
Hold the corresponding stick, knob, slider,
etc. in the position you want the servo
to move to when the fail safe function is
activated and push the RTN button for one
second.
*The set position is displayed in percentage.
*If you want to return that channel to the hold mode, move
the cursor to the "F/S" item and push the RTN button to
switch to the data input mode. Select the F/S mode by
scrolling the Push dial. A confirmation message appears and
then change the mode by pushing the RTN button.

Warning
For safety, always set the fail safe functions.
●Remember to set the throttle channel fail safe function so that
the servo moves to the maximum slow side for airplanes and
to the slow side from the hovering position for helicopters.
Crashing of the model at full high when normal radio waves
cannot be received due to interference, etc., is very dangerous.
●If the battery fail safe is reset by the throttle stick, it may
be mistaken for an engine malfunction and will be reset at
throttle slow and the model will continue to fly. If you have
any doubts, immediately land.
