USING THE 200DX
MENU FUNCTIONS
Bottom Black. There are two selections available: Off and On. The factory setting is Off. With this setting the 2OODX 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 200DX remembers the Bottom Black setting when powered off.
Diagnostic. Two options are available: Hide and Show. The factory setting is Hide. Selecting Show brings up the Diagnostic screen. See the Using Diagnostic section for more information.
