If you are using the 250DX in Simulator when no transducer is connected,
any selected options are lost when the unit is powered off. The 250DX will
return to Factory Settings, or options selected when last used with a
transducer, if no transducer is connected.
IMPORTANT: A transducer must be connected to the 250DX in
order to retain user settings selected when in simulator mode. If
no transducer is detected, the unit defaults to pre-selected
options when powered off.
What You See On-Screen
Your 250DX uses a 128 V x 64 H matrix
FSTN LCD display. This display provides
outstanding viewability in all light
conditions over a wide range of

At initial power-up, the 250DX uses

The digital depth number shows the water depth directly beneath the
transducer location.
Depth Range.
The depth range is shown to the right of the screen. The upper
number is 0 indicating the surface of the water. The lower number is one of
the nine depth ranges available that best match the depth of the water. As the
