9 Levelling system operation

Working area

The optimal working area for the Sonic-Ski

plus with ground and cable

sensing lies between 30 cm and 40 cm.
In this range, the actual value shown on the remote control display is
constantly on; outside of this range, the display flashes (positioning
aid).
The Sonic-Ski

plus should be set to a distance of approx. 35 cm from

the reference.

Ground

Cable

Approx. 35 cm
