If there is no free servo channel available, the vario can be connected in parallel with any other servo.
However, the pulse lead (yellow or white or orange colour) of the Y-cable leading to the vario has to be
disconnected and a remote mode selection is not possible. The vario will remain in the altimeter mode.

Transmitter settings
Select the proper switch or slider and make sure that the servo travel is set to +/- 100% and the middle
position at 0%. Normally this is the basic setting.
Next make sure that the TX switch is controlling the output to which the vario is connected.
The next step is to adjust the “servo” travel to control the vario.
All radios, except Multiplex radios using the native Multiplex pulse length
1. Switch/slider in forward position: Set travel to
– 100%
(1.0 msec)
2. ditto in middle position: Set travel to
0%
(1.5 msec)
3. ditto in backward position: Set travel to
+ 70%
(1.85 msec)
4. If available, set “fail safe position” to +150% (> 2.1 msec)
Multiplex transmitter with native MPX pulse (NOT in “Uni”-pulse mode)
1. Forward position:
- 100%
(1 msec)
2. Middle position:
-20%
(1.5 msec)
3. Back position:
+ 50%
(1.85 msec)
4. If available, failsafe position at + 100%, 110% (> 2.1 msec)

Important note:
It is always advisable to temporarily connect a servo to the receiver output dedicated for the vario in order to
check the mode settings of the transmitter switch/slider. Even more advantageous is a test unit capable of
direct pulse length readings (for instance UniTest by SM-Modellbau).
