SIMULATOR
The X-25B has a simulator built into it that can show a simulated bottom signal with fish. All features of the X-25B work normally when the simulator is in use. You can change the range, zoom, and use the alarms as desired. To use the simulator, press the menu key repeatedly until the SONAR SIM menu ap- pears. Now press the up arrow to turn it on. Repeat the above steps to turn it off, or turn the unit off and back on again.
