Reference Manual and Installation Manual
Simulate mode allows you to become familiar
with the unit off the water. In Simulate mode, the
NS3100 DEPTH functions normally except the
transducer is ignored and the unit generates this
data internally. The word SIMULATE flashes at the
top, left corner of the screen.
Turn the unit on and off with the auxiliary power switch on the boat. The unit does not have its own power
switch. When you turn it off, any settings you have made are retained.
If the word
SIMULATE
flashes at the top, left of the display, then the unit is in simulate mode (see section 2-4).
