Producl Desdiplion
l. Product DescriDtion
the Model
F-2000 is a dual frequency navigation echo sounder
desisaed to comply fully
with
IMO Resolution MSC. ?4(69) Annex
4.
Built aroud
an 8-inch daylisht-viewins,
hish
conhast
@lor TFT LCD scr€en, the
equipment displays the boitom
toposaphy usins a total of seven user-deffnable ease
on-the €ye anslog
strength-level colors representing various
layers of the bottom
suatum.
The display can be Bet to show the bottom contou
slone in a single color via a
menu
sdded
plocedule.
Disital depth
readout ie also available usins easy to
read larse fonts with a clear
on screen
indicatioo of
rbe
refFrence of measu"ehelt
(from
lbe warertine, trdsducer
or keeD, and in meters,
fathoms or feet. To omply with the IMO resolution, the depth
must
be indicated in meters lor navisational
puposes.
With appropfiate
optionsl sensors
plugged
in, the ship's I,AT/LON coordiraies,
speed,
headins and water temperature will also be displayed at
tle same time.
A battery.-backed realtine calendar clock
is built in to indicate the date and time in
UTC or in the desircd local tine. With an appmpdate
GPS sensor
plugged
in, the time
is automaticaly Fefercnced
to the atomic
precision
GPS time.
Up
to 24 hous of sounding data will be stored in non-volatile
memory
at
apFoximately
twrsecond iDtervals, together with associated
date and time, mnge md frequency in
use
plus position
dd water tenperature, and can be
played
back
easily
with a devoied
key. The user can revie*
the
stored
data acrcss any 1s-minute segment at any
point
in
time ove!
ihe
past
24 hous though a specially desisned windo$,. The data can
be
output on demdd in NMEA-{183
(IEC
61162-1)-{onpatible
format via rear
panel
comectors for use in shore-based applications. and
is
protected
against a 6yet€m reset.
An easy-to-use menu system
is ircorpomt€d to set the hansducer draft, depth
rcference, echo threshold
level,
echo
display mode, etc. in addition to operatins
paranetem
to be selected maiily at
installation tine. Umutholized acc€6s to the menu
system can
be
prevented
with
password
enby, if desired.
Equipped with a
poweful
I kW RMs dual frequency bansceiver,
the F-2000 opemtes oD
two difiercnt channels
(chamel
A md chamel B) sepuately. the channel can be easily
switched
with a devoted &ont
panel
ken A 200W low-power dual frequency tlansceiver
is
optionaly
available lor operatiotr using ELAC 50 and 200 kHz transducers. and STN
ATI-{S
SW 6016
100 kHz transduceft-
The output
power
level is adjustable, autonaticaly to suit the range in use, or manuatly
where more
power
is needed
in

levets de autonaticaly controlled for
hands-free operatioD. Manual overide of both functions is atso
possible
for each
operating channel.
If it is des ed
to display
echosram
for a lonser
pe
od of time, lower feed rates
(plot
speeds) can
be
chosen
without affecting the souding nte specified for the depth mnge
in use, tlereby
allowirs
the clrent information upilating rate ta be maintained
resardless of the feed speed in use.
?ossible inteference ftom other echo 6ounde$ operating in the vicinity can be
effectively eliminated or rcduced with a +-step noise reductioD
tunction.
