Storing the focus position
• Focus positions can be stored only by means of the
manual control or the PC.
• A maximum of five focus positions can be stored.
• If a sixth focus position is stored, the one nearest to it will be
cancelled.
• Each focus position can be cancelled individually.
• The system will travel to each of the individual focus
positions in the sequence in which they were stored.
• Switching off the system cancels all of the stored
focus positions.
