Display Speed.
Display Speed controls
the rate at which the graphic information
moves across the display. There are 5
possible speeds; the fastest rate (5) is the
factory setting. If your boat is stationary or
moving very slowly for extended periods, it
may be desirable to update the display at
a slower rate. The closer the update rate matches boat speed, the more
accurate is the graphic depiction of the terrain beneath your boat.
Use the UP and DOWN ARROWS to select the desired update rate. (1) is
the slowest, (5) is the fastest. Use the MENU button to advance to the next
menu.
The Display Speed setting is remembered when the unit is powered off.
Battery Alarm.
The Battery Alarm Option allows you to select the voltage
level at which the Battery Alarm activates.
At the Battery Alarm menu (under options),
you will note that the default setting is OFF.
Push the DOWN ARROW BUTTON to select
the feature ON. Push the DOWN ARROW
BUTTON again to move into the ADJUST
BATTERY ALARM setting. Using the UP and
DOWN ARROW BUTTONS, select a voltage
between 9.0 and 12.0.
When the voltage drops below your selected voltage, an audible alarm will
sound, and a battery alarm icon will be displayed on screen with current
voltage level.
Bottom Black.
There are two selections
available: Off and On. The factory setting is
Off. With this setting, the 450TX displays
the bottom using 4 level grayscale. This
allows you to determine the texture and
relative hardness of the bottom. Selecting
Bottom Black “ON” causes the unit to
blacken in the display below the bottom.
