PEED
selects the speed at which the
bottom information moves across the display.
Options available range from 1 (very slow) to
eight (very fast). Selecting a faster rate shows
more information in the chart window; however it moves across the display
very quickly. Selecting a slower rate keeps the information on the display
longer, but the chart information becomes compressed and may be more
difficult to interpret. Setting Chart Speed in proportion to boat speed is often
preferred.
The Chart Speed setting is retained in memory when the 320 is turned off. The
factory setting is 6.

IGHT
activates the display back light and selects
the brightness level. The light is manually
controlled except when the
320 first powers up.
During start up, the back light turns on at full
brightness so the display will be visible at night. However, the back light
automatically decreases in intensity until it is off. Selecting the Control Panel
during the automatic off process keeps the back light on at the last intensity
level.
Light setting is not retained in memory when the 320 is turned off.

ONTRAST
enhances the viewability of the LCD by
making it darker or lighter. Selecting a higher
number darkens the display; selecting a lower
number lightens the display. The
320 uses
sophisticated electronics to automatically adjust the contrast level; however at
times of extreme heat or cold manually adjusting the contrast for best display
may be needed.
