2.3. Alignment Controls
The following alignment controls and jumpers are provided within the equipment for
setting the general operating parameters. For the position and layout of the preset alignment controls,
see Figure 2-3, overleaf. For normal operation of the equipment, these controls will not need to be
altered.“Set” or “Enabled” implies that the jumper is on.
Do not adjust these settings without consulting a technical information file.
