Each servo moves to the neutral position except
the throttle servo which moves to the slow position
that was just set.
6 Pail safe for all channels can be set with one touch
by setting the sticks and switches of the all channel
to any predetermined position and pressing the FS
button [36] one time.
7 The FS function can be set for all channels and any
servo deflection angle in this manner. When using
FS in all channels the function select switch must
be set to the FS A L L position.
8 Since this FS function is memorized by the trans-
mitter which transmits the data every 60 seconds,
even when the receiver power switch is set to OFF,
resetting is unnecessary.
9 After those settings, set switch [35] to OFF-to pre-
vent erroneous setting.
10 When button [36] is pressed twice, setting FS in
flight, etc., the servo position of the second is
memorized in FS and transmitted.
1 1 To clear the preset FS information, set switch [35]
to reset position switch [34] to position 1 and press
buttons [32] and [33] simultaneously. FS of all the
channels is cleared and all the servos move to the
neutral position.
FS function/HOLD function
The FS function is turned on with button [32] and
the HOLD function is turned on with button [33] as
previously described.
FS (Fail safe function)
FS is a function which moves the servo of each chan-
nel to a position preset on the transmitter when no
radio waves are received by the receiver from the
transmitter or when continuous strong noise is receiv-
ed for about one second or longer. The set operates
by the hold mode in one second and then, by the FS
mode. When the noise or interference disappears and
normal radio waves are received in approximately one
second, FS is released.
HOLD (Hold function)
HOLD is a function which stops all the servos speci-
fied by HOLD (by button [33] to the last correct
command immediately before the erroneous signal
was received.
When the noise, interference, etc. disappears and
normal radio waves are received, HOLD is released.
Set the FS function and HOLD function as you like.
•The operation of the servos can be checked by set-
ting the transmitter and receiver power switches to
ON.
•When switch [35] is switched to TEST-A, the servos
move half-side first and then, come back to neutral
and repeat the other-half from channel 1 to channel
8. (Channel select switch [34] to TEST-ALL position
at this time.) The servos set by the channel select
switch do not operate. (If set to 5, the landing gear
servo does not operate.)
•When switch [35] is switch to TEST-B. all the servos
operate linearly over their full travel. (Channel select
switch [34] in TEST-ALL position at this time.) Only
the servos set at the channel select switch are oper-
ated.
• The servo test is started by pressing button [32] and
is stopped by pressing button [33].

BFS MEMORY SETTING
1 BFS (Battery fail safe function) is a function which
moves the throttle servo to a preset position as set
by the FS when there is only a small amount of
power left in the receiver Nicd battery. ( I f not
set, the throttle servo will be set to medium slow
automatically.)
2 The BFS setting method is the same as the FS
usage method previously described.
3 To release the throttle servo from the preset posi-
tion set by BFS and regain control, lower the
throttle lever in the slow direction. When the
throttle lever reaches a certain point, BPS will be
released and the throttle servo can be controlled
for 36 seconds.
4 Setting this throttle
memory setting, and is done as follows:
•First, set switch [35] to BFS MEMO.SET and set
switch [ 3 4 ] to position [3] (throttle channel.).
• Next, while watching the movement of the servo,
set the throttle lever to the desired position (be-
tween slow and medium slow recommended) and
press buttons [32] and [33] simultaneously. This
completes BFS memory setting.
•This memory allows setting the throttle to any
position, slow to high.
•Lamp [A] of monitor lamps [24] goes out at the
point where BFS is released, this allows BFS to
be checked.
•When there is little power left in the receiver
Nicd battery, the throttle servo automatically
stops at the position set by BFS, BFS is released
when the throttle lever is moved to the memoriz-
ed point. Throttle can then be controlled for 36
seconds by throttle lever
•When the BFS status comes out during flight,
immediately lower the throttle lever to release
BFS. then quickly land.
Function setting can be confirmed by means of lamp
[A] of monitor lamps [24].
1 When switch [35] is at FS SELECT
When lamp [A] is on, HOLD and when lamp [A] is
off, FS.
2 When switch [35] set to ALL FS, off.
3 When switch [35] set to ATV and button [32] or [33]
pressed, blink.
lever point is called BFS
