•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

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

Set

Button

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

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

and

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)

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.
