SIMULATOR
The X-28 has a simulator built into it that can show a simulated bottom signal with fish. All features of the X-28 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 a 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.
