2. Introduction 
We are delighted that you have decided to purchase the 
MULTIPLEX  ROYALevo radio control system. The 
ROYALevo was introduced early in 2002, and constitutes 
a modern digital radio control system, which represents 
a further milestone in the development of radio control 
systems by MULTIPLEX. In the overall design, develop-
ment and production of this system we have invested 
all our experience of several generations of radio con-
trol equipment. The result is a universal, ergonomically 
efficient radio control system of modern design which is 
simple to operate, and which is suitable for use both 
hand-held and in a transmitter tray. And - not least - the 
    ROYALevo is MADE IN GERMANY. 
We placed particular emphasis on convenience of op-
eration during the development of the system software. 
The  ROYALevo offers you a wide range of functions 
selected by experienced users, and these cope effort-
lessly with any model from simple two-axis gliders to 
complex large-scale models and helicopters. Despite its 
comprehensive features, the transmitter is simple to 
operate and easy to understand. 
The essential features of the ROYALevo are as follows: 
•  Ergonomically efficient case, suitable for hand-held 
or tray use, with precision stick units which swivel 
to suit your personal preference 
•  Graphical folding screen (132 x 64 pixels) with variable 
contrast 
•  Easily accessible digital trims in a cruciform arrange-
ment, giving an entirely new feeling to the trims 
•  Low-cost standard RF module* with plug-in crystals, or 
synthesizer RF module* with software channel selection 
•  9 or 12 channels 
•  20 or 36 model memories 
•  6 menu buttons for fast, direct access to the main 
menus 
•  5 function buttons and two 3-D digi-adjustors for user-
friendly programming 
•  Detailed menu texts, selectable language, various lan-
guages available 
•  Comprehensive set-up and mixer facilities for fixed-wing 
models and helicopters 
•  Sample models (templates) minimise programming 
effort required 
•  Unrestricted assignment of transmitter controls, 
switches and servos 
•  4 flight phases per model memory 
•  5 timers 
(3 alarm timers + transmitter and model times) 
•  Facilities for selective Teacher/Pupil (Trainer) operations 
as standard 
We are confident that you will quickly learn to appreci-
ate the ROYALevo, and enjoy using it to control your 
models over a period of many years. Please take a little 
while to familiarise yourself with the system, referring 
constantly to these instructions which are intended to 
help you. 
Yours – the MULTIPLEX team

3. Safety notes 
! These operating instructions are an integral part 
of the product, and contain important informa-
tion and safety notes. They should therefore be 
stored in a safe place where you can refer to 
them at any time. If you ever dispose of the 
equipment be sure to pass on the instructions to 
the new owner. 
! Read these safety notes!  
Read the instructions carefully! Please do not at-
tempt to use the equipment until you have read 
these operating instructions thoroughly, to-
gether with the following safety notes (included 
in these instructions or supplied separately). 
! It is not permissible under any circumstances to 
make technical modifications to the radio control 
system itself or its components. Use genuine 
MULTIPLEX accessories and replacement parts 
exclusively (especially transmitter battery, crys-
tals, aerial, ...). 
! If you wish to use the system in conjunction with 
products made by other manufacturers, it is up 
to you to carry out checks to ensure their quality 
and compatibility. Every time you make any 
change to the system, carry out a careful check of 
the functions, and check the effective range. 
Don’t operate the system or the model if you are 
not sure everything is working correctly; first lo-
cate the fault and eliminate it. 
! Warning!  
Radio-controlled models are not playthings in 
the usual sense. Building these models, installing 
the RC system, and operating them all demand 
technical knowledge, due caution and a respon-
sible, safety-conscious approach. If you are neg-
ligent or make mistakes, the result may be seri-
ous damage and injury. As manufacturers, we 
have no control over your methods of building 
and operating any model, so all we can do is 
point out these hazards expressly. We deny all li-
ability. 
! A model, which is out of control, for whatever 
reason, is capable of causing serious personal in-
jury and damage to property. It is essential that 
you should take out suitable third-party insur-
ance, so that you are covered if, in spite of all 
your care, an accident should occur. 
! Always keep to the following sequence when 
switching the equipment on and off, as this a-
voids the danger of an electric power system 
bursting into life unexpectedly: 
1. When switching on:  
Transmitter ON first,  
then receiver ON.  
Connect flight battery and switch power system 
ON 
2.  When switching off:  
First disconnect flight battery and switch power 
system OFF  
Receiver OFF  
Transmitter OFF
