SAFETY INSTRUCTIONS

Safety Instructions for the Operator

WARNING

Do not open the equipment.

There are no user-serviceable parts inside.

Do not disassemble or modify the equipment.

Fire, electrical shock or serious injury can result.

Immediately turn off the power at the switchboard if the equipment is emitting smoke or fire.

Continued use of the equipment can cause fire or electrical shock. Contact a FURUNO agent for service.

Do not maneuver the vessel based on the depth indication alone.

Grounding may result.

Use the proper fuse.

Fuse rating is shown on the equipment. Use of a wrong fuse can result in damage to the equipment.

CAUTION

Do no turn on the equipment with the transducer out of water.

The transducer may be damaged.

The picture is not refreshed when picture advancement is stopped.

Maneuvering the vessel in this condition may result in a dangerous situation.

Use the proper gain setting.

Incorrect gain may produce wrong depth indication, possibly resulting in a dangerous situation.

NOTICE

A warning label is attached to the equipment. Do not remove the label. If the label is missing or damaged, contact a FURUNO agent or dealer about replacement.

WARNING	Name:
To avoid electrical shock, do not	Warning Label (1)
remove cover. No user-serviceable	Type: 86-003-1011-1

SAFETY INSTRUCTIONS

Safety Instructions for the Installer

WARNING

Turn off the power at the switchboard before beginning the installation.

Fire or electrical shock can result if the power is left on.

Be sure no water leaks in at the transducer or sensor mounting location.

Water leakage can sink the vessel. Also confirm that the transducer and sensor will not loosen by ship's vibration. The installer of the equipment is solely responsible for the proper installation of the equipment. FURUNO will assume no responsibility for any damage associated with improper installation.

Use the specified power cable.

Use of other power cable may result in fire.

CAUTION

Do not install the equipment where air bubbles and noise are present.

Performance will be affected.

The following are guidelines for handling of the transducer cable.

-Keep fuels and oils away from the cable.

-Locate it in a safe place.

-Do no paint the cable.

The sheath of the cable is made of chloroprene rubber (or polychloride vinyl). For this reason do not paint the cable.

Do not turn on the equipment with the transducer out of water.

The transducer may be damaged.

Observe the following compass safe distances to prevent interference to a magnetic compass:

FOREWORD

A Word to FCV-620/585 Owners

Congratulations on your choice of the FURUNO FCV-620/585 Color LCD Sounder. We are confident you will see why the FURUNO name has become synonymous with quality and reliability.

For over 50 years FURUNO Electric Company has enjoyed an enviable reputation for innovative and dependable marine electronics equipment. This dedication to excellence is furthered by our extensive global network of agents and dealers.

This equipment is designed and constructed to meet the rigorous demands of the marine environment. However, no machine can perform its intended function unless operated and maintained properly. Please carefully read and follow the recommended procedures for operation and maintenance.

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

Thank you for considering and purchasing FURUNOequipment.

Features

The FURUNO FCV-620/585 is a dual frequency (50 kHz and 200 kHz) Color LCD Sounder. Comprised of a display unit and a transducer, the FCV-620 displays underwater conditions on a 5.6-inch color LCD and the FCV-585 on an 8.4-inch color LCD.

The main features of the FCV-620/585 are

•Bright color LCD gives excellent readability even in broad daylight.

•Waterproof construction permits installation on open bridge.

•Automatic function being available on detecting fish school and bottom at both shallow and deep depth permits best display.

•User-programmable nav data displays provide analog and digital nav data.

•Alarms: Bottom, Fish (bottom lock and normal), Speed, Water Temperature and Arrival. (Speed, arrival and water temperature alarms require appropriate sensor.)

•White line feature helps discriminate fish lying near the bottom.

•Destination waypoint feature provides range, bearing, and time-to-go to destination waypoint (up to 20 waypoints).

1. OPERATION

1.2Power On/Off

1.Press the /BRILL key to turn on the power.

The unit beeps, the startup screen appears, and then the equipment checks the ROM and RAM for proper operation. After the completion of the equipment check, the last-used display appears.

Startup screen

2.To turn off the power, press the /BRILL key more than three seconds.

The time remaining until power is turned off is counted down on the screen.

Note1: If "ROM/RAM check error!" appears, try to press any key except the /BRILL key to start operation. However, the equipment may not work properly. Contact your dealer.

Note2: The first time you turn on the power (or any time the power is applied after a memory reset), the installation menu appears. See the figure below.

When this occurs, press the MENU/ESC key twice to close the menu.

2.To adjust brilliance, press the /BRILL key.

Continual pressing changes the brilliance continuously (0→1→...→9→8→...→0→ 1→...). “0” is the dimmest and “9” is the brightest.

After selecting “Brill” by using S or T, you may also use W or X to adjust brilliance.

3.To adjust contrast, after selecting “Contrast" by using S or T, use W or X (only for FCV620). “0” is the lowest and “9” is the highest.

4.Press the ENTER key to save the setting and close the window.

Note: When the power is reapplied after turning off the equipment with minimum brilliance, minimum brilliance will be set after the equipment goes through its initial start up. (The start up screen appears with the maximum brilliance.) Adjust the brilliance as necessary.

1.4Choosing a Display Mode

1.Rotate the MODE knob to open the mode setting window, which is displayed for five seconds.

2.Rotate the MODE knob again to choose the display mode desired.

The screen you chose appears soon thereafter.

Single frequency display

Low frequency (50 kHz)

The sounder uses ultrasonic signals to detect bottom conditions. The lower the frequency of the signal, the wider the detection area. Therefore, the 50 kHz frequency is useful for general detection and judging bottom condition.

High frequency (200 kHz)

The higher the frequency of the ultrasonic signal, the better the resolution. For this reason the 200 kHz frequency is ideal for detailed observation of fish schools.

The default mode is bottom lock. To change a mode, see page 16.

Bottom lock display

The bottom lock display provides a normal picture on the right half of the screen and a 10-30 feet (default: 15 feet) wide layer in contact with the bottom is expanded onto the left half of the screen. This mode is useful for detecting bottom fish.

1. OPERATION

Bottom zoom display

This mode expands bottom and bottom fish on the left-half window. This mode is useful for determining bottom contour. When the bottom depth increases, the display automatically shifts to keep the bottom echo at the lower part of the screen.

Marker zoom display

This mode expands chosen area of the normal picture to full vertical size of the screen on the left-half window. You may specify the portion to expand by operating the VRM (Variable Range Marker), which you can shift with S or T. The area between the VRM and zoom marker is expanded. This mode is useful for determining the size of fish in the middle water.
