1.4 Display Modes and Screen Indications
The FE-800 has 3 main display modes: NAV, HISTORY, OS DATA.
The display modes are set in a cycle pattern, and each press of the DISP key changes the
selected mode, in the sequence shown below.
Note 1: OS DATA mode requires external EPFS data (EG:GPS). If [Time Adjust] in the [Service]
menu is set to [Internal] when initial settings are made, the OS DATA screen is
unavailable. To change the [Time Adjust] settings, consult a FURUNO technician.
Note 2: The main display shows output from both transducers if two are connected. If only one is
connected, the display shows only the output from the connected transducer. The menu display may
change slightly for single transducer configurations.
For brevity, this manual uses a two transducer output display for all explanations.
An example of the difference between single and dual frequency displays and their respective marks
and indications is shown below.
