Simulator
The X-65 has a simulator built in that lets you use it as if you are on the water. All features and functions of the unit are usable. A message appears occasionally to remind you that the simulator is on.
To use the simulator, press the MENU key, then press the up or down arrow keys until the "System Setup" menu appears. When it does, press the right arrow key. Now press the up or down arrow keys until the "Simulator" label is highlighted. Finally, press the right arrow key. The X- 65 returns to a sonar screen with simulated echoes scrolling across the screen.
Preset Options
The X-65 "remembers" all settings such as units of measure, auto/ manual, sensitivity, even when power is removed from the unit. To return the X-65 to the factory settings, highlight the "Preset Options" label on the "Sys- tem Setup" menu, then press the right arrow key. The X-65 returns to the full chart screen with all settings returned to their factory values.
Keel Offset
The X-65 measures water depth from the face of the transducer. Since the transducer is below the surface of the water, this distance is not the exact water depth. If the transducer is one foot below the surface, and the X-65 reports the water depth as 30 feet, then the depth is actually 31 feet.
You can calibrate the depth reading using the keel offset feature. First, highlight the "Keel Offset" label on the "System Setup" menu, then press the right arrow key. The screen shown at
right appears. The current bottom depth shows in the upper left corner of the screen. The keel offset shows in the upper right corner. In this example, we need to change the keel offset so that the X-65 will add one
