1.13.2 How to set and use a sector with vertical mode
In Vertical display mode, the SECTOR knob selects a preset width for the vertically
scanned sector.
The setting range is 6° to 180° in 16 steps, as shown in the table below.
To increase the width, turn the SECTOR knob clockwise.
To decrease the width, turn the SECTOR knob counter-clockwise.
You can also alternate between full-range scan and half-range scan with the FULL/
HALF SECTOR key .
The full-range scan shows 180° degree coverage around your ship and the half-range
scan shows a 84° area in the train direction (see section 1.11.3 for details on vertical
train).
