22 Hovering throttle ratcheted knob
•Trims the throttle servo independently from the
pitch control servo (without regard to mixing).
Since the throttle servo can be trimmed without
interfering with other mixing, this knob is very
convenient when trimming the throttle while
hovering.
• When the throttle lever [3] is at about the center,
the throttle servo throw can be adjusted about
25% of the total travel with this knob.
•When the throttle lever [3] is at the low or high
sides, the throttle servo does not operate even if
this knob is turned.

23 Throttle hold switch (TH switch)
Right ON, Left OFF.
•This switch is used during auto-rotation. If this
switch is set to ON when the throttle lever [3] is
in the maximum slow position, the throttle servo
will stop at the position (idling or engine stop)
set at trimmer [8] on the trimmer panel at the
back of the transmitter. At this time, the time set
at trimmer [7] (throttle hold delay) is applied and
the pitch control servo is set to the optimum
pitch for auto-rotation set with trimmer [5]. This
setting can be made without regard to the posi-
tion of the pitch control high side trimmer lever
[13]
•When fail safe switch [12] on the trimmer panel at
the back of the transmitter is set to the INH posi-
tion, the throttle hold function is inoperative.
When it is set to the T.HOLD position, monitor
lamp [D] comes on to indicate that the throttle
hold function is set.
If the TH switch [23] is then set to ON, lamp [D]
goes out to indicate that throttle hold is being
performed.
Lamp A
When the power switch [30] is set to ON, this lamps
comes on and the pointer of the level meter de-
flects. At FS data transmission, this lamp goes out
momentarily and data transmission can be moni-
tored. The lamp goes out once every 60 seconds.
When the internal Nicd battery approaches full
discharched, this lamp starts blinking. This alarm
indicates that the power error backup function is
activitated the memory and circuit (memory, ATV,
FS, etc.) is not functioning.
Lamp B
When fail safe switch [13] on the trimmer panel at
the back of the transmitter is to the IDLE 1 posi-
tion (idle up 1 function
ON), this lamp lights.
When the idle up 1 switch [19] is set to ON, this
lamp goes out.
Lamp C
When fail safe switch [14] on the trimmer panel at
the back of the transmitter is set to the IDLE 2 6
position (idle up 2 function ON), this lamp comes
on. When the idle up 2 switch [21] is set to ON,
this lamp goes out.
Lamp D
When fail safe switch [12] on the trimmer panel at
the back of the transmitter is set to the T.HOLD
position (throttle hold function ON), this lamp
comes on. When the throttle hold switch [23] is set
to ON, this lamp goes out.
When the power switch [30] is set to ON, lamp [[A]
will go out momentarily. This indicates automatic
data transmission on and is not a failure.
Functions priority
Lamp B (Idle up 1 )
Lamp C (Idle up 2 )
Lamp D (Throttle hold)
The function priority is hold -> idle up 2 -> idle
up 1 . Lamps B, C, and D come on when the
pertinent fail safe switch (13, 14, 12) is set to the
ON position. When the idle up 1 switch [19] is set
to ON, lamp [B] goes out. Keeping the idle 1
switch [19] in the ON position, try setting the idle
up 2 switch [21] to ON. Lamp B comes on and
lamp [C] goes out, indicating that the idle up 2
function has priority. Similarly, if the throttle
hold switch [23] is set to on while the 1 switch [19]
and 2 switch [21]
are ON, lamps B and C go out,
indicating that the throttle hold function has
priority.
