•FS (FAIL SAFE) AND HOLD FUNCTIONS
HOW TO USE FS (FAIL SAFE) (THROTTLE CHANNEL AS AN EXAMPLE.)
Set Function Select Switch 49 to FS SELECT.
Set transmitter and receiver power switches to
ON and check servo movements.
While switching the Channel Select Switch 48
from 1 to 8 in order, set the channel (s) to be
used with FAIL SAFE by pressing Button 46
and those to be used with HOLD by pressing
Button 47 . (In this example, set CH3 to FS
with Button 46.)
Move the throttle lever to maximum slow posi-
tion, and press the FS Set Button 36 on the
transmitter back.
CH3 is now set to LOW throttle for the FS
function. After setting FS, turn the Channel
Select Switch 48 and Function Select Switch
49 to OFF.
Test FS by turning the transmitter power
switch to OFF. (In this example, all servos
should move to neutral except the throttle
servo which should move to the LOW position
that was just set.)
Fail Safe for all channels selected can be set
with one touch by moving the sticks and
switches of all the channels to the desired posi-
tions and pressing the FS Set Button 36 once.
(Switch 49 previously set to FS ALL.)
FS settings are retained in the transmitter
memory circuit and transmitted automatically
every 60 seconds (Monitor Lamp A goes out
momentarily during data transmission.) There-
fore, resetting before each flight is unnecessary
even though the receiver switch has been turned
OFF.
After FS settings have been made, always set
Function Select Switch 49 to OFF to prevent
erroneous settings.
To clear all FS settings, set Switch 48 to Posi-
tion 1, then press buttons 46 and 47 simul-
taneously.
FS/HOLD CAN BE CONFIRMED BY MONITOR LAMP.
• Function status can be confirmed by means of Monitor Lamp A .
When Function Select Switch 49 is at FS SELECT: Lamp A ON = HOLD
Lamp A; OFF= FS
• When Switch 49 is set to FS ALL, Lamp A is OFF.
• When Switch 49 is set to ATV and Button 46 or 47 is pressed. Lamp A, blinks.
•BFS (BATTERY FAIL SAFE) AND BFS MEMORY
•BFS (Battery Fail Safe) is a warning function
which moves only the throttle servo to the same
position as set for FS when there is only a small
amount of power left in the receiver Nicd bat-
teries. (If no FS position is set, the throttle servo
is moved to medium slow.)
•When BFS occurs, the throttle servo can be re-
leased and throttle control regained for 36
seconds by lowering the throttle lever to IDLE.
• The throttle stick position at which throttle con-
trol is regained is programmable. This is known
as BFS Memory and is set as follows:
Set Function Select Switch 49 to BFS MEMO
SET and set Channel Select Switch 48 to Pos.
3 (Throttle).
Set the Throttle stick to the desired release
point (between Slow and Medium Slow recom-
mended) and press Buttons 46 and 47 simul-
taneously. BFS Memory is now set.
Set Switches 48 and 49 to OFF.
Whenever BFS occurs in flight, lower the throt-
tle stick to regain control and immediately land
the aircraft.
