the receiver. In practice this means the longest time in 
which the radio control system went into Fail-Safe mode.

Operating voltage (R-VOLT)
Check the receiver’s operating voltage constantly. If it is 
too low, you must under no circumstances continue to 
operate your model, and certainly not launch it.
The low receiver voltage warning can be adjusted within 
the range 3.0 to 6.0 Volt in the “SERVO TEST” sub-menu 
under “ALARM VOLT”. If the voltage falls below the 
threshold, an audible signal (repeated double beep, long 
/ short) is generated, and in all the receiver sub-menus 
“RX …” you will see “

” at top right. At the same 

time the parameter “R-VOLT” is highlighted in the “RX 
DATAVIEW” sub-menu.
The current receiver battery voltage is also shown in the 
basic display; see page 24.

Minimum operating voltage (L.R-VOLT)
“L.R-VOLT” shows the receiver’s minimum operating 
voltage since the last time it was switched on. 
If this voltage differs signifi cantly from the current 
operating voltage “R-VOLT”, this could mean that the 
receiver battery is being overstressed by the servos, 
causing collapses in battery voltage. If this should occur, 
we recommend installing a higher-performance receiver 
battery to ensure maximum operating safety.

Sensor 1 + 2
Shows the values of the optional telemetry sensor 1 
and, if present, sensor 2 in Volt and °C. You will fi nd a 
description of these sensors in the Appendix.

OUTPUT CH (Channel select)
Select the “Channel” line if necessary using the arrow 
buttons. Press the 

 button to highlight the 

value fi eld. Now use the 

 or 

 buttons to set the 

desired channel (e. g. 01). The following parameters 

REVERSE (servo reverse)
Sets the direction of rotation of the servo connected to 
the selected control channel: ON / OFF

CENTER (servo centre)
The “CENTRE” line displays the current pulse width in 
μs of the control channel selected in the “OUTPUT CH” 
line.
The displayed value varies according to the current po-
sition of the transmitter control which affects this control 
channel, and also its trim position.
A pulse width of 1500 μs corresponds to the standard 
centre position, and therefore the usual servo centre 
setting.
To change this value, select the “CENTRE” line and 
press the 

 button. Move the corresponding 

transmitter control to the desired position, and press the 

 button again to store the current transmitter 

control position. This position is now stored as the new 
neutral position.

TRIM (trim position)
The purpose of the “TRIM” line is to provide fi ne ad-
justment of the neutral position of a servo connected to 
the control channel selected in the “OUTPUT CH” line. 
Adjustments are made in 1 μs increments using the ar-
row buttons of the right-hand four-way button. The value 
in the “CENTRE” line can be adjusted over the range 
+/- 120 μs around the TRIM value set here.
Default setting: 0 μs

TRAVEL–/+ (servo travel –/+)
This option can be used to place a limit on servo travel
