10.2. Switching on “normally”

10.2.1. RF module excl. Scanner installed

If the transmitter is fitted with an RF module without

the optional Scanner, one of three possible sequen-

ces will occur when you switch on; they are described

below:

Pre-condition: The RF Check parameter is set to ON

in the menu Setup, Transmitter.

a.) RF module switched on for

the first time: no RF channel

has been set.

Switch on with the L button

pressed in, and select an RF

channel (Î b.).

b.) Use the 3-D digi-adjuster to

select an RF channel, then

switch the transmitter

OFF - ON or

press any menu button or

ENTER to activate operation

without RF transmission.

c.) Activate RF transmission by

pressing any menu button or

ENTER.

! If Check RF is OFF:

If you have set the RF check to OFF in the menu

Setup, Transmitter (not recommended), the se-

lected channel confirmation described under b.) does

not occur before an RF signal is broadcast.

10.2.2. RF module installed, Scanner installed

If your transmitter is fitted with an RF module with

the

optional Scanner, the following two possibilities arise.

Pre-condition: the parameter Check RF is set to ON

in the menu Setup, Transmitter.

a.) The selected channel was

already in use when the trans-

mitter was switched on.

An RF signal is not broadcast.

Start the Scanner by pressing

any menu button or ENTER.

b.) The RF channel is already

set, and is free for use.

Activate RF transmission by

pressing any menu button or

ENTER.

! If Check RF is OFF:

If you have set the RF check to OFF in the menu

Setup, Transmitter (not recommended), the se-

lected channel confirmation described under b.) does

not occur before an RF signal is broadcast.

10.3. Switching on when no RF module

is installed

If the transmitter is switched on with no RF module

fitted, these two screen displays appear in turn:

Fig. 10.3.1.: Transmitter type, Fig. 10.3.2: No RF modul

Firmware version, languages installed

The message No RF remains on the screen for about

one second.

After this the program continues with the throttle

check (Î 10.4.), or moves on directly to the last used

Status display (Î 10.6.).

10.4. Switching the transmitter on

with throttle-check active

Throttle-check is a safety function. If you are about to

fly a powered model, the throttle check (throttle lock)

prevents an electric motor bursting into life unexpec-

tedly if you switch the system on when the throttle

channel is not at idle

You will find the parameter Check Thr. in the menu:

Setup, Transmitter:

¡Transmitter

¨Exit

Safety

Check Thr. ON_

Check RF ON

The factory default setting is ON. The conditions for

throttle-check are different for fixed-wing model aircraft

and helicopters; for this reason they are described

separately in the next two sections.

10.4.1.

Throttle-check for fixed-wing models

This warning appears if:

x Throttle-Check (Check Thr.) is set to ON (see above)

and

x the throttle control is not

in the idle position (or at

the motor OFF position)

and

x the Throttle CUT switch has not

been operated.
