Instructions for RX-7/9-DR M-LINK 2.4 GHz receivers # 985 5319 (10-02-24/MIWA) • Errors and omissions excepted! •

MULTIPLEX

x Switch the receiver ON, or connect the battery:

 The binding procedure runs, the receiver LED

flashes at high frequency

(LED code 2 Î 8.1).

x Now release the SET button.

! Note: the binding process starts automatically when

the receiver is used for the first time, and after a RESET -

even if you have not pressed the SET button.

2. Once the transmitter and receiver are bound to each other,

both switch automatically to normal operation (Î 8.4):

 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.

8.3.2 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:

x Reduce the distance between your transmitter and the

receiver aerials.

x Ensure that your transmitter is switched ON in binding mode.

x Repeat the binding procedure.

8.4 Switching the receiver ON and OFF

in normal operations

8.4.1 Sequence of switching ON and OFF

To switch the M-LINK RC system ON, please use this

procedure:

1. Switch the transmitter ON.

2. Switch the receiver ON.

The receiver LED flashes slowly and evenly

(LED code 3 Î 8.1):

 An M-LINK signal is being received,

the RC system is ready for use.

To switch the M-LINK RC system OFF, please use this

procedure:

1. Switch the receiver OFF.

2. Now switch the transmitter OFF.

8.4.2 Locating and correcting faults when switching ON

Fault:

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:

x Is the transmitter switched on?

x Is the transmitter generating an M-LINK signal?

x Are the transmitter and receiver bound to each other?

x Have you carried out a receiver RESET (Î 8.2,Î 8.6)?

x Have you made changes to the setting for “Fast Response”

(Î 8.3) or “France mode” (Î 8.3)?

Error:

The receiver LED stays off after switching on

(LED code 0 Î 8.1).

Cause:

The operating voltage (battery voltage) is too low.

Remedy:

x Recharge the receiver battery or drive / flight battery.

8.5 HOLD and FAIL-SAFE

If no signal is picked up, or if the received data is corrupt, the

last valid information is passed on to the servos in order to

bridge the signal loss (HOLD mode).

If interference should occur and FAIL-SAFE has been invoked,

the servos (...) run to a previously defined position at the end of

the HOLD period. FAIL-SAFE mode ends as soon as error-free

signals are picked up again.

The factory default setting for the HOLD period is 0.75 seconds.

This period can be adjusted to meet personal requirements

using the MULTImate (Î 11.) or the PC program RX Data-

Manager (Î 11.).

FAIL-SAFE is switched OFF in the receiver’s default state (as

delivered), and after a RESET. FAIL-SAFE is activated using the

SET button on the receiver, or - in the case of certain trans-

mitters - “by radio”.

If you wish to disable FAIL-SAFE again, the receiver must be

reset to the default state (RESET Î 8.6). After a RESET you

must repeat the binding procedure (Î 8.3)!

! 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:

1. The receiver LED must not display any errors

(LED code 3 Î 8.1).

If it does: switch the receiver OFF, then ON again.

2. Use your transmitter to move all the servos (and the speed

controller) to your preferred FAIL-SAFE positions. Press the

SET button briefly (0.5 to 1 second). The FAIL-SAFE posi-

tions are now stored for all servo channels, and the LED

flashes the confirmation signal (LED code 5 Î8.1).

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:

For testing the FAIL-SAFE function only, the receiver can be

operated with the transmitter switched off. Caution: if the FAIL-

SAFE settings are incorrect, the motor could burst into life: injury

hazard!

After sixteen seconds in FAIL-SAFE the receiver ceases to send

control signals to the servos (default setting; this period can be

changed using the MULTImate or RX DataManager (Î 11.)).

Analogue servos and some digital servos (see instructions) then

become “soft”, to avoid them being stalled. Modern speed con-

trollers switch themselves off. However, some digital servos

remain “hard” and maintain their last position.

The MULTImate or RX DataManager can be used to activate or

disable the FAIL-SAFE function servo by servo. Example:

throttle only to Idle / OFF, all other servos = HOLD.

8.6 RESET to factory default settings

The receiver settings can be reset to the factory default settings.

If you do this, all the settings you have entered, such as binding

information, FAIL-SAFE settings ... are lost permanently.
