 the Throttle CUT switch has not been operated.
As long as the on-screen warning is visible, ...
 the servo assigned to throttle (or the speed control-
ler) remains in the Idle position (or motor OFF),
and
 all other control functions can still be operated
normally.
The throttle lock is terminated when ...
 the throttle control is moved to the Idle position (or
motor OFF),
or
 the Throttle CUT control is operated (default button H)
or
 you press the REV/CLR button.

Caution! The motor might start to run!
If you override the throttle lock using the REV/CLR
button or Throttle CUT, the throttle channel will jump
to the value defined by the assigned throttle control.

Throttle-check for model helicopters

Helicopter throttle is affected by the following trans-
mitter controls:
a. Throttle CUT switch (default: button H).
b. Direct Throttle switch
(DTC = Direct Throttle Control, default: switch N).
c. Collective pitch stick via the throttle curve.
d. Throttle limiter (default: slider F).
This warning appears on-screen if:
 Throttle-Check (Check Thr.) is set to ON ( 10.4.)
and
 the collective pitch stick is not at the Idle position
(collective pitch minimum)
and
 the Throttle CUT switch is not active.
As long as the note is visible on the screen, ...
 the servo assigned to throttle (or the speed control-
ler) remains in the Idle position (or motor OFF)
and
 all other control functions can still be operated
normally.
The throttle lock is terminated when ...
 the collective pitch stick is moved to the Collective
Pitch Minimum position (provided that: point P1
on the throttle curve is lower than or equal to the
set value for Throttle Minimum Min.)
or
 EMERGENCY throttle OFF is operated (default:
button H)
or
 the throttle limiter is moved to the Minimum position
or
 you press the REV/CLR button.
!
Caution! The motor might start to run!
If you override the throttle lock using the REV/CLR
button or Throttle CUT, the throttle will jump to the
value defined by the assigned throttle control.
10.5.
The transmitter and receiver must be "introduced" to
each other once; this process is known as "binding".
! Note:
You will find general information on the subject of
binding, and on fault-finding and correction relating to
the binding procedure, in the operating instructions
supplied with your MULTIPLEX M-LINK receiver.
The binding procedure in detail:
1. Place the transmitter and the receiver aerial(s) im-
mediately adjacent to each other.
2. Switch the ROYALevo, ROYAL SX or ROYAL SX
M-LINK transmitter ON in binding mode:
 Hold button L on the transmitter pressed in.
 Switch the transmitter ON.
 Release button L:
 The red LED on the transmitter flashes rap-
Indicator for
the throttle
and throttle
3. Switch the M-LINK receiver ON in binding mode
limiter con-
(see the
trols
M-LINK receiver operating instructions):
 The binding process is now in progress.
4. Once the transmitter and receiver have detected
each other, both units automatically switch over
to regular transmit / receive mode (Normal opera-
tions  11.):
 The red LED on the transmitter flashes ap-
proximately every two seconds, and the flash-
ing message "BINDING!" disappears.
! Note: the binding process usually only takes a few
seconds
10.6.
Regular range checks are very important - even when
using a 2.4 GHz system - in order to ensure reliable
operation of the radio control system, and to give you
a chance to detect sources of interference in good
time. This applies in particular:

Before the use of new or changed components, or
existing components in a new or modified arrange-
ment.

Before re-using radio control system components
which were previously involved in a crash or a hard
landing.

idly, and the message "BINDING!" flashes
on the transmitter screen in all status dis-
plays with the exception of status display 4.
