For applications where the model is not operated directly above
or below the transmitter, the optimum aerial orientation is verti-
cally upwards; this applies in particular to model cars and boats.
!
Important:
Never point the aerial directly at the model. For physical reasons
the signal radiated from the aerial is at its weakest in an imagi-
nary line extending straight out from the aerial.

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) immediately
adjacent to each other.
2. Switch the ROYALevo, ROYALpro or ROYALpro 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 rapidly, and
the message "BINDING!" flashes on the transmitter
screen in all status displays with the exception of
status display 4.
3. Switch the M-LINK receiver ON in binding mode (see the
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 operations
The red LED on the transmitter flashes approximately
every two seconds, and the flashing message
"BINDING!" disappears.
! Note: the binding process usually only takes a few seconds.

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 arrangement.
Before re-using radio control system components which were
previously involved in a crash or a hard landing.
If you have encountered problems on a previous flight.

Important:
Always ask a second person to help you with your range
check, so that one of you can secure and observe the model.
If possible, carry out the range check when no other trans-
mitters are operating.
Preparations, carrying out the range check:
1. Select "Range check" mode on the transmitter:
F
Hold button
on the transmitter pressed in.
Switch the transmitter ON.
F
Release button
The red LED on the transmitter now glows constantly,
and the message "RANGE!" flashes on the transmitter's
screen in all the status displays with the exception of
status display 4.
2. Switch the M-LINK receiver ON.
3. Carry out the range check as described in the operating
instructions supplied with your M-LINK receiver.
4. When the range check is completed, switch the M-LINK
transmitter OFF, and then ON again, in order to switch
back to full range.
! Caution: selecting "Range check" mode reduces the
transmitter's output power. The transmitter emits an audible
signal every ten seconds or so to warn you of this. Never
attempt to fly a model with the transmitter set to reduced
output (Range check mode)!

This is the procedure for operating your ROYALevo, ROYALpro or
ROYALpro M-LINK transmitter in normal mode:
1. Switch the ROYALevo, ROYALpro or ROYALpro M-LINK
transmitter ON:
The red LED on the transmitter flashes once every two
seconds.
2. Switch the M-LINK receiver ON.
The M-LINK system is now ready for use.

The 2.4 GHz ISM band offers the facility to transmit model data
back to the transmitter. If you are using a telemetry-capable
M-LINK receiver, the actual voltage of the receiver power supply
will be displayed directly on the integral screen of your ROYAL-
evo, ROYALpro or ROYALpro M-LINK transmitter. If the battery
voltage falls below a certain threshold, the transmitter also emits
an audible signal to warn you that the receiver battery is almost
flat.
For more information on this feature, please refer to the opera-
ting instructions supplied with your telemetry-capable M-LINK
receiver.

In Fast Response mode, which operates at the ultra-rapid pulse
rate of 14 ms, up to twelve servo channels are available. This
reduced pulse rate can cause analogue servos to oscillate or run
jerkily.
If this occurs, or if you need to use the maximum of sixteen
servo channels, it is possible to switch Fast Response mode
OFF on the ROYALevo, ROYALpro or ROYALpro M-LINK
transmitter. The pulse rate is then 21 ms.
Please refer to the notes in the operating instructions supplied
with your ROYALpro M-LINK transmitter in this regard.
