These operating instructions are an integral part 
of the product, and contain important information 
and safety notes. Please store them in a safe place, 
where you can find them at any time, and pass 
them on to the new owner if you sell the receiver.

  High-quality 5-channel / 7-channel receivers assembled 
using the latest SMT methods, exploiting MULTIPLEX  
2.4 GHz M-LINK technology. 
 Supplementary 
signal 
pre-amplification:  
For maximum sensitivity and great range. 
  In-line connectors arranged on the front and back: 
Ultra-compact dimensions: suitable for models with very little 
internal space. 
  HOLD / FAIL-SAFE function. 
  Integral SET button and LED:   
For binding, FAIL-SAFE programming, RESET and  
displaying operating status information. 
  Telemetry / feedback channel capability: 
Receiver battery voltage and connection quality  
= standard features. 
Integral sensor interface for connecting external sensor 
modules via MSB (MULTIPLEX Sensor Bus). 
  Prepared for two-receiver operation: 
Diversity lead (# 8 5070) required. 
  Prepared for serial servo output: 
Servo outputs as sum signal – SRXL-MULTIPLEX.  
The receiver’s first twelve channels are carried by a three-
cord lead (# 8 5070) via the receiver’s B/D socket, e.g. for 
power supply / servo management systems, or for flybarless 
systems in model helicopters.  
  Prepared for selecting one sensor address as “priority 
address”:  
The selected sensor value is updated at a faster rate than all 
the other sensor values. 
  Integral error counter / data logger: 
For voltage and signal errors. 
 Compatible 
with 
the 
MULTImate (# 8 2094). 
  Integral PC interface:  
Carry out updates and adjustment using the MULTIPLEX 
Launcher PC program in conjunction with the UNI USB PC 
lead (# 8 5149).

Please read the instructions before using the receiver. 
Use the receiver only for the intended applications  
(
 4.). 
Ensure the power supply is of adequate capacity (
 6.). 
Observe the installation notes (
 13.). 
Carry out regular range checks (

PPLICATIONS
 
The RX-5 M-LINK and RX-7 M-LINK 2.4 GHz receivers (abbre-
viated to RX-5/7 M-LINK in this document) are radio control 
receivers intended exclusively for use in model sport. It is 
prohibited to employ them for other purposes such as full-size 
(people-carrying) vehicles or industrial installations. 
Typical applications for RX-5 M-LINK and RX-7 M-LINK re-
ceivers:
 
  Gliders and electric gliders up to about 2.50 m wingspan 
  Small to medium-sized RC helicopters with rotor diameters 
up to about 1 m 
  Model aircraft with electric and I.C. power systems and 
wingspans up to about 1.60 m 
  RC model cars 
  RC model boats 
  RX-5/7 M-LINK 2.4 GHz receivers can only be operated in 
conjunction with transmitters which utilise MULTIPLEX M-
LINK transmission technology.

RX-5/7-DR M-LINK receivers work within a broad range of vol-
tages from 3.5 V … 9.0 V, i.e. they can be used with receiver 
batteries consisting of four to six NiXX cells or 2S LiPo / 2S LiIo 
(LiXX). 
! Note: 
if you intend to use a five-cell or six-cell NiXX battery, 
or a 2S LiPo or 2S LiIo pack, it is essential to check that all the 
servos, gyros and other components connected to the system 
are approved for use with this higher operating voltage. 
Note: ensure that the power supply is adequate 
A power supply system in good condition and of adequate capa-
city for the specific application plays an indispensable role in the 
safe operation of any model: 
  Use only high-quality receiver batteries of adequate capacity. 
Balance and maintain them carefully, and charge them fully. 
  Ensure that all cables are of adequate conductor cross-
section. Keep all wiring as short as possible, and use the 
absolute minimum of plug / socket connections. 
  Use high-quality switch harnesses exclusively. 
  Brief collapses in the power supply voltage (lasting a few 
milli-seconds) have no adverse effect on the receiver. Longer 
voltage collapses to below 3.5 V may cause a receiver reset, 
resulting in a brief interruption in reception. This may be due 
to a receiver battery which is almost flat, too weak or
