Simulator
This unit has a built-in simulator that shows a simulated bottom signal

water; all features and functions of the unit are usable. A message ap-
pears occasionally to remind you that the simulator is on.
To use the simulator, repeatedly press
MENU until the SIMULATOR menu
appears. Press
↑ to turn it on and press PWR to clear the menu. Repeat
the steps above to turn it off. The simulator automatically will be
turned off when you power off the unit.
