INTRODUCTION

Congratulations on your choice of the FURUNO FCV-667 Color Video Sounder. We are confident that you will enjoy many years of operation with this fine piece of equipment.

For over 50 years FURUNO Electric Company has enjoyed an enviable reputation for quality and reliability throughout the world. This dedication to excellence is furthered by our extensive global network of agents and dealers.

The FCV-667 is just one of the many FURUNO developments in the field of echo sounding. The compact, lightweight but rugged unit is easy to install and operate and is suitable for both fresh and saltwater applications.

This unit is designed and constructed to withstand the rigors of the marine environment. However, to obtain optimum performance from this unit, you should carefully read and follow the recommended procedures for operation and maintenance. No machine can perform to the utmost of its ability unless it is installed, operated and maintained properly.

We would appreciate feedback from you, the end-user, about whether we are achieving our purposes.

Thank you for considering and purchasing FURUNO equipment.

Features

The FCV-667 dual-frequency (50kHz and 200kHz) color video sounder has a large variety of functions, all contained in a splash-proof rugged plastic case that is compact to fit small boats.

The principal features of the FCV-667 are

User-friendly design for simplified operation.

•

A wide variety of display modes: bottom-lock expansion, marker zoom and unique bottom

•

zoom displays.

Potent 300 W transceiver.

•

8-color presentation (including background) on a 6" diagonal CRT, providing vivid

•

presentation of underwater conditions.

AUTO function permits unattended range and gain setting operations. The range scale and

•

gain change automatically so that the bottom is displayed in reddish brown or red on the lower half of the screen.

A-scope display gives excellent bottom fish discrimination, vital for bottom trawler and

•

lobster/crab potter.

Digital and analog displays of navigational data.

•

iii

Alarms: fish, bottom, water temperature (requires appropriate sensor).

•

Six pulselengths for excellent performance on both shallow and deep ranges.

•

Universal 12-24 VDC power supply drawing 30 W of power at maximum.

•

Water temperature/speed sensor optionally available.

•

PRINCIPLE OF OPERATION

This Color Video Sounder determines the distance between its transducer and underwater objects such as fish, lake bottom or seabed and displays the results on a 6-inch color screen.

It does this by utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 4800 feet (1500 meters) per second. When a sound wave strikes an underwater object such as fish or sea bottom, part of the sound wave is reflected back toward the source. Thus by calculating the time difference between the transmission of a sound wave and the reception of the reflected sound wave, the depth to the object can be determined. In a sense an echo sounder can be thought of as being an extremely sophisticated and quick timer, since it is capable of resolving time differences shorter than one thousandth of a second.

The entire process begins in the display unit. Transmitter power is sent to the transducer as a short pulse of electrical energy. The electrical signal produced by the transmitter is converted into an ultrasonic signal by the transducer and transmitted into the water. Any reflected signals from intervening objects (such as a fish school) are received by the transducer and converted back into an electrical signal. It is then amplified in the amplifier section, and finally, displayed on the screen.

The picture displayed by the color video sounder is made up of a series of vertical scan lines, one for each transmission. Each line represents a "snapshot" of what has occurred beneath the boat. The series of snapshots are accumulated side by side across the screen, and the resulting contours of the bottom and fish between the bottom and surface are displayed. The amount of history of objects that have passed beneath the boat over a series of transmission varies from less than a minute to a few minutes, depending on how you adjust the unit.

2. BASIC OPERATION

2.1 Turning the Power On/Off

Turn the [MODE] switch clockwise to turn the power on. The unit starts with the settings used before it was turned off last time. Note that there is a few seconds delay prior to display of the picture until the CRT warms up. To turn the power off, turn the switch fully counterclockwise.

2.2 Adjusting Brilliance

Use the [BRILL] key to adjust the brilliance. The selected brilliance level is shown on the display as below. There are six levels of brilliance including off. Keep the brilliance moderate to extend the life of the CRT.

2.3.2 Display mode description

HF, LF (high frequency, low frequency) mode

The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency of the pulse the wider the detection area. Therefore, the 50 kHz frequency is useful for general detection and judging bottom conditions, while the 200 kHz frequency is useful for detailed observation of fish schools.

DUAL frequency mode

This mode provides the 50 kHz picture on the left-half of the screen and the 200 kHz on the right half, and is useful for detecting fish schools which have different reflection characteristics with frequency. For example, a school of tiny fish like minnow returns stronger echoes on a high frequency compared to a low frequency.
