Jag översätter en handbok för en buss, och då står det så här i avsnittet om takfönstret:

To open the ceiling window, remove the plastic protection and pull the handle down.
Then push the window outwards.
The ceiling window is an emergency exit and should be used only for that purpose.
In the event of an emergency, break the seal and turn the lever.
If the emergency exit has been used, take the following steps:
a. Open the anchoring points (raise them manually).
b. Position the ceiling window for anchoring.
c. Turn the level and anchor the window with the anchors.

Vad kan Anchoring översättas med här?
