7.18  Statistics (26)

  This setting indicates whether the pieces are to be recorded

according to the average diameter or the top diameter in the
statistics.

  0 = top diameter, 1 = average diameter.

NOTE!
If this setting is changed, the statistics should be emptied in order to get
all pieces recorded in the same way.

7.19  Diameter Limit (27)

  This setting is used to determine whether the diameter limit concerns

the diameter at the centre of the piece or at the top.

  0 = top, 1 = centre.

7.20  Preselection Extender Button (28)

  The programming of a certain preselection key to a preselection

extender button.

  Detailed information is found in enclosure "4. Enabling the extended

preselection".

7.21  Factory Settings (29)

  Not necessary in normal use.

  Locked if the text "Lock" is displayed (factory settings cannot be set).

  The factory settings set the preselections and program the

preselection keys and set part of the special settings. After the factory
settings the parameter values must be checked and corrected.

  Detailed information is found in enclosure "1. Factory settings".

7.22  Butt End Reverse (30)

  Setting of the butt end reverse distance. The butt end reverse is used

when a new tree is taken into the grapple. When a tree is in the
grapple, part of the butt end of a tree leaves unreachable to the
knives, so reverse can be used to delimb this part of a tree.

  The butt end reverse is in use when automatic feed (feed by

preselection) is selected. The reverse can be interrupted by pressing
the keys "Feed forward" or "Feed backward".
