To adjust the bottom level setting, see section 2.2.
Note: Do not switch transducer (frequency) at the
Junction Box when setting the bottom level. If it is necessary to set bottom level for a different frequency, turn
off the FE-800, switch transducer at Junction Box and
then turn on the FE-800 again.
If the level is set too low, the FE-800
may not be able to distinguish the
bottom from fish echo and the depth
indication may be unstable.
If set too high, the depth indication
does not appear.
CAUTION
19
Page 28
2. SYSTEM MENU
2.2.2 TVG level
TVG (Time Varied Gain) compensates for propagation attenuation of the ultrasonic waves,
reducing surface noise to provide a smooth display. The TVG lowers receiver sensitivity at the
time of pulse emission and gradually increases it with time, thereby making objects of same
reflectivity at different depths appear at the same intensity or colors on the display.
The TVG working depth is down to approximately 150 m on the 200 kHz system and 350 m on
the 50 kHz system. Outside this range the echoes from the seabed and fish schools are received
in full level. There is no perceivable deterioration in performance.
To adjust the TVG level or the TVG distance, see section 2.2.
Note: Do not switch transducers (frequency) at the Junction Box when setting the TVG level. If it
is necessary to set TVG level for a different frequency, turn off the FE-800, switch
transducers at the Junction Box and then turn on the FE-800 again.
2.2.3 Echo offset
The echo offset feature functions to compensate for too weak or too strong echo level.
If the on-screen echo level appears to be too weak or too strong and the level cannot be adjusted
satisfactorily with the GAIN control, see section 2.2 to adjust the TVG level.
2.3 How to Set TX Rate

TROUBLESHOOTING
WARNING
Do not open the cover.
There are no user-serviceable parts
inside.
Refer any repair work to a qualified
technician.
Do not apply paint, anti-corrosive
sealant or contact spray to coating or
plastic parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.
NOTICE
3.1 Checklist
Regular maintenance is essential for good performance. Checking the items listed below on a
regular basis will keep the equipment in good shape for years to come.
Item Action
Cable run If conductors are exposed, replace cable.
Display unit ground If corroded, clean.
Ship’s main voltage If out of rating, correct the problem.
3.2 Cleaning the Display Unit
Dust or dirt on the cabinet can be removed with a soft cloth. If desired, a water-moistened cloth
may be used. Do not use chemical cleaners, they may remove paint and markings.
To clean the LCD, wipe the LCD carefully to prevent scratching, using tissue paper and an LCD
cleaner. To remove dirt or salt deposits, use an LCD cleaner, wiping slowly with tissue paper so
as to dissolve the dirt or salt. Change paper frequently so the salt or dirt will not scratch the LCD.
Do not use solvents such as thinner, acetone or benzene for cleaning. Also, do not use a
degreaser or an antifog solution, as they can strip the coating from the LCD.
3.3 Transducer Maintenance
Marine life on the transducer face will result in a gradual decrease in sensitivity.
Check the transducer face for cleanliness each time the ship is dry-docked. Carefully remove any
marine life with a piece of wood or fine-grade sandpaper.

3. MAINTENANCE AND TROUBLESHOOTING
3.4 Replacing the Fuse/Battery
If a fuse blows, find the cause before replacing it. Use only designated fuses. Using the wrong fuse
will damage the unit and void the warranty. Consult your dealer for replacement of the fuse.
A battery installed on a circuit board inside the transceiver unit preserves data when the power is
turned off. The life of the battery is about ten years. When the battery voltage is low, a warning
message "Displayed time may be incorrect. Please re-set the clock." appears after the self-test.
When this happens, contact your dealer to request a replacement of the battery. Press any key to
proceed to the main display screen.
Note: The message "Displayed time may be incorrect. Please re-set the clock." appears when the
FE-800 is turned on for the first time. In this case, the battery does not need replacement, however
the clock must be set.
