PRINCIPLE OF OPERATION
The FE-700 uses ultrasonic pulses to detect the seabed and other underwater objects. The display unit
contains all basic electric circuits and logic processor. Electrical pulses are converted into acoustical
energy in the transducer fitted on the ship’s 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 frequency, 50 kHz or 200 kHz.
The high frequency has a narrow beamwidth and is immune to aeration when the ship is going astern or in
rough weather. The low frequency has a wide beamwidth and more powerful sounding capability.

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.

1.7 Range Scale
If the depth goes out of the correct display area,
increase or decrease the range until the seabed
appears near the center of the screen.
Adjust the Range Control, and current range
selection is shown in the range display window.
RANGE 5 m
In the AUTO mode, the range scale is
automatically adjusted. See section 1.9 for
details.
1.8 Gain Control
The GAIN Control adjusts the sensitivity of the
receiver. The AUTO mode provides automatic
adjustment and you are normally not required to
adjust it. Current setting is shown at the upper
left-hand corner. Adjust the GAIN Control and the
following window appears.
GAIN 5.5
Adjust the GAIN Control so that a slight amount
of noise remains on the screen. Generally, use a
higher gain setting for greater depths and a lower
setting for shallower waters. Adjusting range is
between 0.0 and 10.0 in 0.5 steps.
1.9 Automatic Operation
The automatic function automatically selects the
proper gain, range scale and clutter level
according to depth. It works as follows:
• The range changes automatically to locate the
bottom on the lower half of the screen. It jumps
to one step shallower range when bottom
echoes reach a halfway point of the full scale
from top and to one step deeper range when
they come to the lower edge of the scale.

Noise
Light-blue dots may appear overall screen. This
is mainly due to dirty water or noise. This noise
can be suppressed by adjusting CLUTTER (in
reality, Threshold of the amplifier).
When the automatic mode is on, the
suppression setting is automatically adjusted.
For manual override, do the following:
1. Select MENU with the MODE Selector.
2. Select CLUTTER by pressing the [▲] key.
3. Press the [ - ] or [+] key to select clutter
rejection 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 Suppressing Interference
Interference from other acoustic equipment
operating nearby or other electronic equipment
on your boat may show itself on the display.
To suppress interference, do the following:
1. Select MENU with the MODE Selector.
2. Select INTERFERENCE REJECT by
pressing the [▲] or [▼] key.
3. Press the [ - ] or [+] key to select degree of
suppression desired; OFF, IR1, IR2 or IR3.
The higher the number the greater the
degree of suppression.
Note that oversuppression will weaken the
sensitivity.

2.5 Trend
The future trend of the seabed depths can be
predicted over a specified period of time (See
page 13). The trend index is set with the item
TREND INDICATOR and appears at the top left
corner. The default setting is ON.
θis inclination angle of bottom.
−2°≤θ≤2° 2°<θ≤10° 10°<θ≤45° 45°<θ≤90°

2.6 Interval
The interval for sampling data for the
LOGBOOK and HISTORY modes can be set
with INTERVAL, among 5 s, 1 min and 2 min.
The default setting is 1 min.
