1.27 Parallel Index Lines

Parallel index lines are useful for keeping a constant distance between own ship and a
coastline or a partner ship when navigating. Index lines are drawn in parallel with the No. 2
EBL (No. 2 EBL must be active). The orientation of the index lines is controlled with the
EBL control (without effecting the EBL indication) and the intervals between the lines
adjusted with the VRM rotary control (provided that No. 2 VRM is active).
Maximum number of the index line can be set on INITIAL SETTING 3 menu: 2, 3 or 6.
