Unlock
Select the symbol (1, Figure 4-133).

(2) red.
If symbol (2) is not red after approx. 10 seconds, this means
that the locking pins are under load.
To relieve the load, carefully retract and extend a little.
If removing the load does not cause unlocking, you must lock
the telescopic section (Locking the telescopic section, page
4-70) and restart unlocking.

You can telescope the telescopic section once it is unlocked.
