FX-20
4.1 TURNING TRANSMITTER ON AND OFF
• Slide the main power switch on the Transmitter (Tx) to the
right.
• The right hand red monitor indicates RF radiation after first
monitoring the local RF environment.
• The Display shows the symbol for RF radiation
Upto 36 FASST transmitters may be operated simultane-
ously. If the band is full, then the Tx will not radiate RF and
waits for a few moments to retry.
Note:
An SD-card increases the start-up phase time somewhat, be-
cause all the data must be read from the card.
Attention:
Do not turn off during the initialization phase (Left-hand moni-
tor-LED flashes red), as this may damage the settings.
SWITCHING THE TRANSMITTER OFF
• Slide the main power switch on transmitter downwards
• The RF radiation will stop and the data stored in the working
memory will be stored either in the internal memory or writ-
ten to the SD-card.
If the Tx is switched on again during the power-off and
memory storage phase, the data back up will be ignored.
4.2 LED Monitor
Two Status LEDs are located on the front face, which indicate
the Tx status by means of a flash sequence.

4.3 STICK ADJUSTMENT
The FX-20 Tx has new precision gimbal sticks, fitted with ball
bearings and long-life potentiometers to the latest industry
standards. Emphasis has been placed on the best control “feel”
around the neutral point of both stick axes.
EXTENDING STICK LENGTH
The stick length is fully adjustable and may be set to the opti-
mum length to suit the pilot’s need.
• Loosen parts A and B
• Adjust stick length to the desi-
red position
• Lock part A and B
ADJUST SPRING CENTERING TENSION
The spring return centring force of the joysticks can be ad-
justed to suit the indivual control feel needs of the pilot. Slide
the locking catch on the rear of the case towards the case top
(arrow). Using a small cross head screwdriver, adjust the spring
tension as shown.
4.4 LIQUID CRYSTAL DISPLAY (LCD)
The large, clear-view and high contrast LCD graphics monitor
(with 128 x 64 dots) supplies the user with all the necessary
information required for programming and operation.
KEY-LOCK
So that no unwanted changes to the programs occur during
flight operation, the S1 key serves also as a key-lock. To lock/
unlock the keys, press S1 key for 1 second. (See illustration).
