F/S Fail Safe F/S Fail Safe (PCM mode only) (PCM mode only)
The Fail Safe function is used to prescribe what the PCM receiver will do in the event radio interference is received, and
doesn’t work FM(PPM) receivers. In this menu, you may select from one of two options of operation for each channel. The
“NOR”(normal) setting holds the servo in its last commanded position, while the “F/S”(Fail Safe) function moves each servo
to a predetermined position.
Throttle channel is set to “F/S” as a default. All the other channels are set to “NOR”.
The use of the failsafe function is recommended from the standpoint of safety. You may wish to set the throttle channel so
that the throttle is moved to idle when there
’s interference. This may give enough warning to allow you to fly towards yourself
and recover from the radio interference. If you choose to specify a failsafe setting, the failsafe data are automatically
transmitted once each minute.
Battery Failsafe Battery Failsafe
Your system provides a second safety function called Battery Failsafe. When the airborne battery voltage drops below
approximately 3.8V, the battery fail safe function moves the throttle to a predetermined position or fast idle, if you haven
’t set
it. If this happens, you should immediately land! If you need to increase throttle for your landing approach, you may
temporarily reset the failsafe function by moving the throttle stick to idle, after which you
’ll have about 30 seconds of throttle
control before the battery function reactivates.
To set the Fail Safe Function: To set the Fail Safe Function:
1. Enter the programming mode. Access the
“ F/S F/S” screen with the MODE key.
2. You can find the channel blinking on the left of the screen, which can be set to the Fail Safe.
The first channel you see is CH1 (aileron). Press DATA Input lever downward when you
need to set Fail Safe. The arrow moves to F/S side. This means this channel has been set
to F/S function. Then move the aileron stick to the position where you want the servo to
move when “F/S
F/S” function works and press DATA INPUT lever downward for about two
seconds while holding the stick. A figure in percentage will be shown with a beeping sound.
Press DATA INPUT lever upward if you want to set
“ NOR NOR”. The arrow moves to “NOR NOR”
side and then this channel will be set to “ NOR NOR” function.
3. Carry out similar procedure like this in setting “F/S” function for other channels. Use Mode
key to show a channel and do the same. But, CH3 (throttle) is set to 20% of the full throttle
for
“F/S” function as a default.
4. Verify that your failsafe programming works by switching off transmitter power and observing the motion of the servos.
