  • Page 5: Introduction

    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.
  • Page 6 • 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.

  • Page 7: Principle Of Operation

    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.

    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.
  • Page 12 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.

  • Page 16: Adjusting Gain

    Adjusting Gain The [GAIN] control adjusts the sensitivity of the receiver. Adjust it 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. Note: The [GAIN] control is inoperative when the automatic mode is active.

  • Page 17: Selecting Picture Advance Speed

    Selecting Picture Advance Speed The picture advance speed determines how quickly the vertical scan lines run across the screen. When selecting a picture advance speed, keep in mind that a fast advance speed will expand the size of the fish school horizontally on the screen and a slow advance speed will contract it. 1.

    Operate the [RANGE] switch and the display shown below appears. Adjust the [RANGE] control again to select a basic range. RANGE: 30 ft Note: The [RANGE] switch is inoperative when the auto function is active. 2.7.2 Range shifting The basic range may be shifted up or down with the [SHIFT] keys ([+], [-]). Press a [SHIFT] key and the display shown below appears.

  • Page 26: White Marker

    2.16 White Marker The white marker functions to display a particular echo color in white. For example, you may want to display the bottom echo (reddish-brown) in white to discriminate fish echoes near the bottom. Note that the bottom must be displayed in reddish-brown for the white marker to function.

  • Page 28: Interpreting The Display

    3. INTERPRETING THE DISPLAY Zero Line The zero line (sometimes referred to as the transmission line) represents the transducer's position, and moves off the screen when a deep phased range is used. Fish School Echoes Fish school echoes will generally be plotted between the zero line and the bottom.

  • Page 29: Surface Noise/Aeration

    Surface Noise/Aeration When the waters are rough or the boat passes over a wake, surface noise may appear near the zero line. As surface turbulence is acoustically equivalent to running into a brick wall, the bottom echo will be displayed intermittently. Similar noise sometimes appears when a water temperature difference (thermocline) exists.

    LIGHT-BLUE BLUE PLEASE CHECK KEYS/SWITCHES. Note: If NG appears instead of OK for any device or panel switch, contact FURUNO for service. Do not attempt to check inside the unit because of the high voltage used in the equipment. 4. To terminate the test, turn the power off.

  • Page 34: Transducer Check

    Transducer Check A simple and reliable check of the transducer is to temporarily replace the transducer with a new one. If the sensitivity is considerably improved through this change, the transducer is probably faulty. This method is especially useful for inside-hull or through-hull installation. Another method is to listen to the transmission sound.
