SAFETY NOTES ! Please read the instructions before using the receiver. ! Use the receiver only for the intended applications (Î 4.). ! Ensure the power supply is of adequate capacity (Î 6.). ! Observe the installation notes (Î 9.). ! Carry out regular range checks (Î 10.). 4. APPLICATION The RX-5 light M-LINK is a radio control receiver intended exclusively for use in model sport applications. It is prohibited to use it for other applications, such as man-carrying vehicles or industrial installations. The RX-5 light M-LINK was designed with minimum possible size and weight as top priority, and for technical reasons such a unit cannot offer the same reception characteristics as a larger, technically more sophisticated and more expensive receiver. In the interests of safety we recommend that you use a larger receiver wherever space permits. Under normal conditions it is certainly possible to obtain excellent reception characteristics with a small receiver such as the RX-5 light M-LINK provided that all the RC system components are carefully arranged, and the receiver aerial correctly deployed. 5. COMPATIBILITY The RX-5 light M-LINK 2.4 GHz receiver can only be used in conjunction with transmitters which use MULTIPLEX M-LINK transmission technology. As of January 2010 these are: • ROYALpro 7, 9 and 16 M-LINK. • ROYALevo or pro 7, 9 and 12 with firmware version V3.xx and the HFM4 M-LINK 2.4 GHz RF module. • PROFImc 3010, 3030 and 4000 with the HFM3 M-LINK 2.4 GHz RF module. • COCKPIT SX M-LINK. • MULTIPLEX transmitters with the HFMx M-LINK 2.4 GHz RF module. 6. POWER SUPPLY The RX-5 light M-LINK receiver works with a wide range of voltages from 3.5 V … 9.0 V, i.e. with receiver batteries con-sisting of 4 to 6 NiXX cells or 2S LiPo / 2S LiIo batteries. ! Note: if you wish to use a five-cell (six-cell) NiXX battery, check that all the servos, gyros and other components to be connected to the system are approved by the manufacturer for use on operating voltages up to 7.5 V (9.0 V). If you wish to use a 2S LiPo (2S LiIo) pack, check that all the servos, gyros and other components to be connected to the system are approved by the manufacturer for use on up to 8.4 V (8.2 V). ! Note: ensure that the power supply is adequate A power supply system in good condition and of adequate capacity 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 defec-tive, cables of inadequate cross-section, poor-quality con-nectors or an overloaded or defective BEC system.

RECEIVER CONNECTIONS This receiver employs the UNI connector system, which is com-patible with the connector systems used by most radio control manufacturers (e.g. HiTEC, robbe/Futaba, Graupner/JR). The receiver sockets are marked as follows: 1, 2, 3, 4, 5 Servo sockets, channel 1, 2, 3, 4, 5. ! Note: a separate receiver battery can be connected to all five servo sockets (1 … 5). ! When connecting the receiver battery, servos, speed controllers ... it is essential to ensure that the con-nectors are plugged in correctly, and feature compatible pin assign-ments: (see symbol on the receiver)! 8. FIRST USE, FUNCTIONS 8.1 LED codes LED code Description LED Code 0 LED OFF Battery voltage too low LED Code 1 LED ON No reception LED Code 2 1,6 sec Binding process running 1,6 sec LED Code 3 Normal reception in progress 1,6 sec LED Code 5 Confirmation signal 8.2 Binding Before it can be used, the receiver must be linked to the trans-mitter using the process known as “binding”. ! Note: The signal output to the servo sockets is switched off during the binding procedure. This means that the servos are “soft”, and do not move, while the motor connected to a modern electronic speed controller remains OFF due to the lack of a signal. Never-theless, it is important to secure the model and keep well clear of the power system. The binding process is necessary in the following cases: • The first time the receiver is used (Î 8.2.1). • After a receiver RESET (Î 8.5). • If you change the “Fast response” setting at the transmitter. Please read the appropriate section in the instructions supplied with your transmitter or RF module. • If you change the setting at the transmitter which defines the transmitted frequency range. For more information on this matter, please refer to the operating instructions supplied with your transmitter or RF module (“France mode”). • If the receiver is to be operated in conjunction with a different M-LINK transmitter. 8.2.1 Sequence of the binding procedure 1. The first step is always to set the transmitter and receiver to Binding mode: a. Place the transmitter very close to the receiver aerial. b. Switch the transmitter ON in binding mode. ! Note: please read the operating instructions supplied with your M-LINK transmitter or RF module for details. c. Switch the RX-5 light M-LINK receiver ON in Binding mode: • Locate the SET button on the top of the receiver and hold it pressed in. • Switch the receiver ON, or connect the battery. • Now release the SET button (not before): ⇒ The binding procedure runs, the LED on the receiver flashes at a high rate (LED code 2 Î 8.1). 2. Once the transmitter and receiver are bound, both units switch automatically to standard transmit / receive mode: ⇒ The LED on the receiver flashes slowly (LED code 3 Î 8.1). ! Note: in most cases the binding process only takes a few seconds. 8.2.2 Binding: locating and correcting faults Fault: During the binding process the receiver LED continues to flash at a high rate after several seconds. Cause: No M-LINK signal of adequate strength detected. Remedy: • Reduce the distance between your transmitter and the recei-ver aerial. • Ensure that your transmitter is switched on in binding mode. • Repeat the binding procedure. 8.3 Switching the receiver ON and OFF in normal mode 8.3.1 Sequence when switching ON and OFF This is the procedure for switching the RC system ON: 1. Switch the transmitter ON. 2. Switch the receiver ON. 3. The receiver LED flashes slowly and evenly (LED code 3 Î 8.1): ⇒ An M-LINK signal is being picked up: the RC system is ready for use. This is the procedure for switching the RC system OFF: 1. Switch the receiver OFF. 2. Only now switch the transmitter OFF. 8.3.2 Locating and correcting faults when switching ON: The receiver LED lights up constantly when switched on (LED code 1 Î 8.1), but does not flash. Cause: No M-LINK signal detected. Remedy: • Is the transmitter switched on? • Is the transmitter generating an M-LINK signal? • Are the transmitter and receiver bound to each other? • Have you carried out a receiver RESET (Î 8.5, Î 8.2)? • Have you made changes to the “Fast response” / “France mode” setting (Î 8.2)? Fault: The receiver LED remains off when the unit is switched on (LED Code 0 Î 8.1). Cause: The operating voltage (battery voltage) is too low. Remedy: • Charge the receiver battery or flight battery, or replace it with a charged pack.
Operating Instructions RX-5 light M-LINK 2.4 GHz receiver MULTIPLEX Modellsport GmbH & Co.KG • Westliche Gewerbestraße 1 • D-75015 Bretten (Gölshausen) • www.multiplex-rc.de Page 3/4 Instructions: RX-5 light M-LINK 2.4 GHz receiver # 985 5316 (10-01-08/MIWA) • Errors and omissions excepted! • © MULTIPLEX 8.4 HOLD and FAIL-SAFE If the receiver detects invalid data (interference), the last valid data is sent to the servos in order to bridge the period of signal loss (HOLD mode). The effect of the FAIL-SAFE setting is that the servos run to a previously selected setting if interference should occur, once the HOLD period (0.75 seconds) has elapsed. In its default state and after a RESET the FAIL-SAFE function is switched OFF, and is only activated when you select the FAIL-SAFE settings for the first time. FAIL-SAFE is set using the SET button on the receiver. ! Note: if you are using a COCKPIT SX M-LINK or ROYALevo / pro / M-LINK transmitter, you can also set FAIL-SAFE directly from the transmitter. If you wish to disable FAIL-SAFE again, the receiver must be reset to the default state (RESET Î 8.5). After a RESET you must repeat the binding procedure (Î 8.2.1)! ! Note: always activate FAIL-SAFE! For safety reasons we recommend that you always activate FAIL-SAFE, and ensure that the selected FAIL-SAFE settings will cause the model to take up as safe an attitude as possible (e.g. motor idle / electric motor OFF, control surfaces neutral, landing flaps deployed, tow-release open, …). Selecting the FAIL-SAFE settings: Use your transmitter to move all the servos (and the speed controller) to the desired position. Hold the SET button pressed in briefly (0.5 to 1 second). This stores the servo positions, and the LED flashes to confirm this (LED code 5 Î 8.1). After sixteen seconds in FAIL-SAFE the receiver no longer sends signals to the servos. Analogue servos and some digital servos (see instructions) then become “soft”, to avoid them being stalled. Modern speed controllers switch themselves off. However, some digital servos remain “hard” and maintain their last position. FAIL-SAFE mode is automatically terminated as soon as the receiver picks up valid signals again. Testing the FAIL-SAFE positions: Move the sticks to positions other than the FAIL-SAFE settings, and then switch the transmitter OFF: the servos should go into HOLD mode briefly (0.75 seconds), and then move to the FAIL-SAFE positions which you previously selected. The FAIL-SAFE positions must always be checked and updated when necessary, e.g. when you install the receiver in a new model. ! Checking the FAIL-SAFE function: Never operate the receiver with the transmitter switched off for longer than it takes to check the FAIL-SAFE function. Caution: the motor could burst into life - injury hazard! 8.5 RESET to default settings The receiver settings can be reset to the factory default values if you wish. If you do this, please note that all your settings (e.g. bound transmitter, FAIL-SAFE settings) will be lost. Hold the SET button pressed in for at least ten seconds (as a guide, the LED goes out when you press the button, comes on again after two seconds, then off again after ten seconds). When the RESET is complete, the receiver LED will flash to confirm the action (LED code 5 Î 8.1). 9. INSTALLATION NOTES • Protect your receiver from vibration, especially in models powered by an internal-combustion engine (e.g. pack it loosely in foam). • Locate the receiver at least 150 mm away from electric mo-tors, petrol engine ignition systems and any other electronic components such as speed controllers for electric motors and drive batteries. Do not route the aerial close to these com-ponents. • Install the receiver in the model in such a way that the aerial is as far away as possible from any conductive material. • If the fuselage is made of conductive material (e.g. carbon fibre), the aerial must be installed in such a way that its active part (approx. the final 30 mm) is located outside the model. • Do not shorten the aerial or the aerial lead. If your model requires a longer or shorter aerial lead, please contact the MULTIPLEX Service Dept. or any MULTIPLEX Service Centre. • Do not deploy the aerial parallel to servo leads, high-current cables or electrically conductive components (e.g. pushrods). • Do not deploy the aerial inside or resting against model components which are skinned or reinforced with conductive material (metal foil, carbon fibre, metallic paints, ...), as they can have a shielding effect. • Note the recommended installation scheme (Î 14., sketches A - C)! • High-current cables, e.g. those attached to the speed con-troller, motor and flight battery, should be kept as short as possible. • Reception quality can be optimised by fitting a special ferrite ring (# 8 5146) or suppressor filter lead (# 8 5057) in the speed controller cable. It is also advisable to fit effective suppressors to conventional (brushed) electric motors (not brushless types) (e.g. use the suppressor set # 8 5020). 10. RANGE CHECKING 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 enable you 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. Carrying out the range check: 1. Select “Range check” mode on your transmitter (see the operating instructions for the M-LINK transmitter or the HFM3 M-LINK / HFM4 M-LINK / HFMx M-LINK 2.4 GHz RF module). 2. The range of the RX-5 light M-LINK receiver must be at least forty metres with the transmitter set to low power. You have reached the range limit when the servos start to move jerkily. There must be line-of-sight contact between the transmitter and the receiver aerial (i.e. the model) during the range check.

If your transmitter features an automatic servo test facility, we recommend that you activate it for one control function (e.g. rudder). This sets up a steady movement of the servo, and enables you to detect the limit of range clearly. Important: Carry out the first range check with the motor switched off. Turn the model in all directions and attitudes, and adjust the aerial position if necessary. For the second range check, run the motor at varying speeds and check that the effective range is not significantly reduced. If there is a marked reduction, locate and eliminate the cause of the interference (caused by the motor, the arrangement of the receiving system and power supply, vibration, etc.). 11.
