Safety Precautions
zHigh Voltage
High voltages are used in the transmitter section which could be life threatening. A
protection cover with the words Danger High Voltage is provided in this section but
wait 10 minutes before inspecting inside.
Even if the power switch is turned off, residual voltages may remain in the capacitors
inside the unit. Before inspection or replacement of parts, discharge this residual
voltage in a safe and correct manner.
zDisconnect Main Power
It is still possible to receive an electric shock caused by unintentionally switching on
the power during repair work. To prevent this from happening, make sure to
completely disconnect the unit from the ship’s main supply before attempting any
inspection.
zDust
Dust can accumulate inside after long periods of use. Allergies can result from the
inhalation of this dust, therefore during inspection and cleaning it is advisable to use a
mask.
zStatic Electricity
Static sensitive semiconductor devices are used in this unit. Before changing the
printed boards be careful not to damage any of these devices due to electrostatic build
up from carpet, clothes, seats, etc.

General information
Chapter 1 General information
1.1 General
The CVS-833/833C series of sounder is composed of two main units, a display unit and a transducer
unit. Transmitting power level can be selected from 600 W (CVS-833) and 1 KW (CVS-833C), using the
same dual-frequency transducer type for 50 KHz and 200 KHz.
The display unit uses a high brightness, 8” TFT (Thin Film Transistor) display to allow an easy viewing
even in daytime operation. The operation is simple and straightforward, using dedicated rotary controls
and user-friendly menus.
By pressing the AUTO key the unit is set to hands-free operation, in which the gain and depth range are
automatically selected to an optimized level by an internal micro-controller chip.
1.2 Applicable standard
The CVS-833/833C is designed and tested to comply with the international standard of IEC-60945 3rd
edition that defines the general requirements of electronic maritime equipment.

Installation
Chapter 4 Installation
4.1 Installation consideration
General
Qualified service technicians should perform the installation of CVS-833/833C series that comprises
the following operations.
(1) Unpacking each component of the system.
(2) Inspection of the exterior of each component unit and accessory.
(3) Checking the ship’s mains voltage and current capacity.
(4) Determining the installation site
(5) Installing the Display unit and transducer
(6) Planning the cable routing and connections
(7) Adjustment and setups
4.2 Unpacking each component of the system
Unpack your package and check if all of the items are identical to what specified in the Device
Composition List in Chapter 2. If not, report this to an insurance agent for tracing missing goods or
refund.
4.3 Inspection of each component unit and accessories
Carefully check the exterior of each component unit for dents, damage, etc. Also check the inside of
component units for electrical and mechanical damages.
4.4 Positioning the units
To achieve best operational performance, the following factors must be considered.
(1) The display unit should be positioned in the location where the external situation can be viewed.
(2) Locate the display so that it provides easy viewing from all likely operator’s positions.
(3) Select a position safe and free from dampness, water spray, rain and direct sunlight.
(4) Provide enough space for servicing. Consider access to the rear panel for connecting various
cables.
(5) Position the display unit as possible away from other radio equipment.
4.5 Cable routing and connections
(1) The transducer cable should be run separately away from other cables such as, radio antenna
feeders, power cables, etc. Under no circumstances should it be in parallel arrangement with other
cables. These precautions are essential to avoid radio interference to/from other equipment
installed on the ship. If this arrangement is no possible, either cable set should be screened with
metal conduit or another form of shielding.
(2) The display unit should be grounded to the hull as short as possible using a thick braided harness
lead connected to the grounding stud at the rear of the display unit.
(3) The power supply cable should be connected directly to the ship’s battery to avoid the conducted
RF noise from other equipment on board.

Installation
4.6 Display installation
The display unit is designed for table mount and flush mount. For detail, refer to the following
paragraphs.
4.6.1 Table mounting
(1) Remove the two fixing knobs that fix the display unit to the mounting bracket.
(2) Remove the display unit from the bracket and place it on a flat and safe area.
(3) Place the mounting bracket to the place where the display unit is to be installed, and fix the bracket
with four (4) tapping screws.
(4) Reset the display unit on to the bracket and fix it using the two screws that were removed in step (1).

CVS-833/833C Chapter 4
Installation
4.6.2 Flush mounting
(1) Cut a rectangle opening that measures 190 mm x 194 mm.
(2) Loosen two (2) fixing knobs that fasten the display unit onto the fixing bracket.
(3) Remove four (4) plastic screw covers, which are fitted on each corner of the display front face.
(4) Put the display on the opening and fix with four (4) tapping screws. In case you use M4 screws to
fix the display, select an appropriate screw length that best suits fixing the unit to the panel
thickness.
(5) Refit the coverings removed in step (3).
