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.

The factory setting is Hide. Selecting Show brings up the
Diagnostic screen. See the Using Diagnostic section for
more information.
