You can telescope the telescopic section once it is unlocked.

Telescoping
If the requirements for telescoping are met, the
symbol (3) flashes.
• Move the control lever in the desired telescop-
ing direction.
The display (1) shows the current extended
length (telescoping in metres).
The current telescope diagram on the display (2)
will change continually.

If extending and retracting several times does not lead to the lock being released,
you must not telescope any further against the stop.
