By traversing thereference marks once in each axis, you will re-establish the display positionrelative to the last known zero. The most you will ever have to move an axis isabout one inch. You must move in a positive count direction. A flashing decimalpoint will indicate that the last position has not been you use an encoder that does not have the Position-Trac feature, the procedurefor recovering your position is slightly different.
