Adjust Display Color/Brightness
Briefly press the red PWR button when the unit is on, and a
menu will appear at the bottom of the display which can be
used to select the color mode and the screen brightness.
Three display color modes are available: NORMAL (normal
viewing), SUNLIGHT (white background for sunlight
viewing) and NIGHT (black background for night viewing).
A multi-color palette designates the strength or intensity of the
returning signal. RED indicates the strongest signal.
YELLOW indicates a mid-level return. BLUE returns are
the weakest. This palette is visible as a progressive color
scale on all screens. Red (the stronget return) is on top and
Blue (the weakest return) is on the bottom. Use this color
scale to determine the strength of return.
NOTE: While strength of return may be used to determine to
hardness of an object, it does not determine the depth of the
object. Use the forward vertical scan or the on-screen cursor
to determine depth of a return.
You can also adjust the display brightness from this menu. If
no buttons are touched for 5 seconds the screen menu will
disappear.
