FE-700 system configuration
The FE-700 uses ultrasonic pulses to detect the seabed and other underwater obects. The display unit
contains all basic electric circuits and logic processor. Electrical pulses are converted into acoustical
energy in the transducer fitted on the ships hull. The processor measures the time of pulses travelling
between the seabed and transducer and displays the water depths in the graphical form or other forms.
The transducers have a specific beam width with respect to their working fre uency, 50 k or 200 k .
The high fre uency has a narrow beamwidth and is immune to aeration when the ship is going astern or in
rough weather. The low fre uency has a wide beamwidth and more powerful sounding capability.

The Mode Selector choose the display mode
among NAV, DBS (depth below surface),
HISTORY, LOGBOOK, OS DATA, HELP, and
MENU.
1.6.1 NAV mode
The depth from the transducer to the seabed
(bottom clearance) is shown on the screen. Note
“BELOW TRANSDUCER” appears at the bottom
of the screen in this mode. If the transducer
setting is DEPTH BELOW KEEL, “BELOW
KEEL” appears at the bottom of the screen.
Default is,
Color: Amber
Range: Automatic range switching
Window: 15 minutes
Shallow depth alarm: 20 m
NOTE: These parameters can be customized to
your preference and the last setting is used at a
next switch-on. This is true on all other modes.
1.6.2 DBS mode
The Depth Below Surface mode provides a
draft-adjusted depth reading and will be useful in
referencing to the nautical chart. The draft should
be adjusted by the DRAFT key according to the
actual draft value. If you find any difficulty to
check for the draft value, use the NAV mode.
When the DBS mode is selected, the message
“Confirm and set ship’s draft to use DBS mode”
appears. Confirm ship's draft and set it by
referring to section 1.12.
BELOW SURFACE appears at the bottom of the
display and the draft value appears at the upper
right-hand corner in the DBS mode.
CAUTION
DBS is not a water clearance below
keel.
Do not use this mode in shallow
waters to avoid grounding.
1.6.3 HISTORY mode
This mode provides a mix of Contour and Strata
displays. The Contour display can be scrolled
over the past 24 h while the right side Strata
display (layers of different colors according to
reverberation strengths) shows the latest
sounding for 5 minutes.
Pressing the [+] or [
- ] key moves the Contour
display forwards or backwards, respectively.

1.6.4 LOGBOOK mode
The LOGBOOK shows time, depth and own ship
position in tabular form in a pop-up window. The
logging is selected with the INTERVAL option on
the menu among 5 s, 1 min and 2 min. (See
section 2.6.)
There are 60 pages and the total memory
capacity is 720 points. Page 60/60 is the latest

Light-blue dots may appear overall screen. This
is mainly due to dirty water or noise. This noise
can be suppressed by ad usting L TTER (in
reality, Threshold of the amplifier).
When the automatic mode is on, the
suppression setting is automatically ad usted.
For manual override, do the following:
1. Select EN with the ODE Selector.
2. Select L TTER by pressing the [䦱] key.
.Press the [ - ] or [+] key to select clutter
re ection level desired. The higher the
number the higher the degree of
suppression. Note that weak echoes may
not be displayed when the clutter circuit is
on.
2.3 Su e ing Inte e en e
Interference from other acoustic e uipment
operating nearby or other electronic e uipment
on your boat may show itself on the display.
To suppress interference, do the following:
1. Select EN with the ODE Selector.
2. Select INTERFEREN E RE E T by
pressing the [䦱] or [䦻] key.
.Press the [ - ] or [+] key to select degree of
suppression desired OFF, IR1, IR2 or IR .
The higher the number the greater the
degree of suppression.
Note that oversuppression will weaken the
sensitivity.
