Chart Scale; Display Brilliance And Key Backlighting - Furuno GD-3300 Operator's Manual

1.9 Chart Scale

1.10 Display Brilliance and Key Backlighting

The chart scale can be adjusted with the [ZOOM IN] and [ZOOM
OUT] keys. Note that the [ZOOM IN] key shrinks the picture, and
the [ZOOM OUT] key "blows up" the picture. With a smaller range,
you may find that the track appears in tiers.
The horizontal range of the display in nautical miles appears at the
top right-hand corner of the Data Display. Whenever the scale is
changed the new range appears momentarily at the screen center.
