  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 ob-
serve the model. 
  If possible, carry out the range check when no other 
trans-mitters are operating. 
Preparations, carrying out the range check: 
5.  Select “Range check” mode on the transmitter: 
  Hold button F on the transmitter pressed 
in. 
  Switch the transmitter ON. 
  Release button F: 
  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. 
6.  Switch the M-LINK receiver ON. 
7.  Carry out the range check as described in the op-
erating instructions supplied with your M-LINK re-
ceiver. 
8.  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  re-
duces  the  transmitter’s  output  power.  The  trans-
mitter 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)! 
10.7.  Fast Response ON/OFF 
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 ana-
logue 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, ROYAL SX 
or ROYAL SX M-LINK transmitter. The pulse rate is 
then 21 ms. 
Please refer to the notes in the operating instructions 
supplied with your ROYAL SX M-LINK transmitter in 
this regard. 
This is the procedure for switching Fast Response ON 
or OFF if you are using a ROYALevo, ROYAL SX or 
ROYAL SX M-LINK transmitter: 
1.  Switch the transmitter ON. 
2.  Press button I on the transmitter. 
3.  Mark the menu point Modulation by rotating one 
of the  
  3-D digi-adjusters, or by pressing the  button. 
4.  Press the ENTER button, or one of the 3-D digi-
adjusters. 
5.  Mark the menu point FastResponse by rotating 
one of the 
  3-D digi-adjusters, or by pressing the  button. 
6.  Press the ENTER button or one of the 3-D digi-
adjusters. 
7.  Select one of the options ON or OFF by turning one 
of the 
  3-D digi-adjusters, or by pressing the  or  but-
tons. 
8.  Confirm your selection by pressing the ENTER 
button, or by pressing one of the two 3-D digi-
adjusters.

must  repeat  the  binding  process  between  trans-
mitter and receiver ( 9.)! 
10.8.  The Status displays
