Some FURUNO products have a battery(ies). To see if your product has a battery, see the chapter on Maintenance. Follow the instructions below if a battery is used. Tape the + and - terminals of battery before disposal to prevent fire, heat generation caused by short circuit.
In the European Union
The crossed-out trash can symbol indicates that all types of batteries |
|
|
must not be discarded in standard trash, or at a trash site. Take the |
|
|
used batteries to a battery collection site according to your national |
Cd |
|
legislation and the Batteries Directive 2006/66/EU. |
||
|
In the USA
The Mobius loop symbol (three chasing arrows) indicates that Ni-Cd and lead-acid rechargeable batteries must be recycled. Take the used
batteries to a battery collection site according to local laws.
Ni-Cd Pb
In the other countries
There are no international standards for the battery recycle symbol. The number of symbols can increase when the other countries make their own recycle symbols in the future.

WARNING
Do not open the equipment.
The equipment uses high voltage that can cause electrical shock. Refer any repair work to a qualified technician.
If water leaks into the equipment or something is dropped into the equipment, immediately turn off the power at the switchboard.
Fire or electrical shock can result.
If the equipment is giving off smoke or fire, immediately turn off the power at
the switchboard.
WARNING
Fire or electrical shock can result.
If you feel the equipment is acting abnormally or giving off strange noises, immediately turn off the power at the switchboard and contact a FURUNO service technician.
WARNING
Do not disassemble or modify the equipment.
Fire, electrical shock or serious injury can result.
Make sure no rain or water splash leaks into the equipment.
Fire or electrical shock can result if water leaks into the equipment.
Do not place liquid-filled containers on or near the equipment.
Fire or electrical shock can result if a liquid spillsWARNINGinto the equipment.
Do not operate the equipment with wet hands.
Electrical shock can result.
Use the proper fuse.
Use of the wrong fuse can cause fire or electrical shock.
ii
CAUTION
Handle the LCD carefully.
The LCD is made of glass, which can cause injury if broken.
Do not transmit with the transducer out of water.
Damage to the transducer can result.
Properly adjust the gain.
Too little gain gives no picture. Too much gain shows excessive noise on the picture. Using the depth data for navigation when the gain is incorrectly set can lead to a dangerous situation.
Too high |
Correct |
Too low |
The data presented by this equipment is intended as a source of navigation information.
The prudent navigator never relies exclusively on any one source of navigation information, for safety of vessel and crew.
The use of two transceivers with the same frequency will result in interference.
When fitting more than one transceiver, ensure the frequencies are different.
Warning Label(s)
Warning label(s) is(are) attached to the equipment. Do not remove the label(s). If a label is missing or damaged, contact a FURUNO agent or dealer about replacement.

1.2How to Turn the Power On/Off
Note 1: Make sure the unit is connected correctly to each transceiver.
Note 2: After turning the unit off, wait at least 5 seconds before you turn the power on again.
Press the 
button to turn the unit on. With the power on, press the 
button again to turn the unit off.
On startup, the unit displays a splash screen for approximately ten seconds, then begins a self-test. The self-test checks the logic circuits, battery status and displays the program version currently in use.

1.4Display 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.
NAV 
HISTORY 
OS DATA
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.
