USING THE 250DX
MENU FUNCTIONS
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. Keep in mind that the closer the update rate matches your 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. 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 250DX displays the bottom using Structure ID.
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. This gives the user easiest recognition of the bottom location, even from a great distance.
The 250DX remembers the Bottom Black setting when powered off.
