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.
