How to discard a used battery
Some FURUNO products have a battery(ies). To see if your product has a battery(ies), see the chapter on Maintenance. Follow the instructions below if a battery(ies) is used. In the European Union The crossed-out trash can symbol indicates that all types of batteries must not be discarded in standard trash, or at a trash site. Take the used batteries to a battery collection site according to your national legislation and the Batteries Directive 2006/66/EU. In the USA The Mobius loop symbol (three chasing arrows) indicates that Ni-Cd and lead-acid rechargeable batteries must be recycled. Take the used batteries to a battery collection site according to local laws. In the other countries There are no international standards for the battery recycle symbol. The number of symbols can increase when the other countries make their own recycling symbols in the future.

PRINCIPLE OF OPERATION

The FE-700 uses ultrasonic pulses to detect the seabed and other underwater objects. The display unit contains all basic electric circuits and logic processor. Electrical pulses are converted into acoustical energy in the transducer fitted on the ships hull. The processor measures the time of pulses travelling between the seabed and transducer and displays the water depths in the graphical form or other forms. The transducers have a specific beam width with respect to their working frequency, 50 kHz or 200 kHz. The high frequency has a narrow beamwidth and is immune to aeration when the ship is going astern or in rough weather. The low frequency has a wide beamwidth and more powerful sounding capability.

The range changes automatically to locate the bottom on the lower half of the screen. It jumps to one step shallower range when bottom echoes reach a halfway point of the full scale from top and to one step deeper range when they come to the lower edge of the scale. The gain is automatically adjusted to display the seabed in specified color.
Monochrome (amber) is the default setting. The Strata display contains multiple colors depending on the reflectivity from underwater objects of the sounding pulses. Red is strongest, followed by brown, orange, yellow, blue, and light blue at the default setting.

MAINTENANCE, TROUBLESHOOTING
6.3 Transducer Maintenance
Do not open the cover. There are no user-serviceable parts inside. Refer any repair work to a qualified technician.
Marine life on the transducer face will result in a gradual decrease in sensitivity. Check the transducer face for cleanliness each time the ship is dry-docked. Carefully remove any marine life with a piece of wood or fine-grade sandpaper.

NOTICE

Do not apply paint, anti-corrosive sealant or contact spray to coating or plastic parts of the equipment. Those items contain organic solvents that can damage coating and plastic parts, especially plastic connectors.
6.4 Replacing the Fuse, Battery
If a fuse blows, find the cause before replacing it. Use only designated fuses. Using the wrong fuse will damage the unit and void the warranty. Three types of fuses are used in the distribution box FE-702. For Display Unit : 3 A x 1 pc (24 VDC) For Digital Depth Indicator: 0.5 A x 2 pcs For AC input: 1 A x 2 pcs The Digital Depth Indicator FE-720 uses one fuse of 1 A, which is inserted in the positive line of interconnection cable. A battery installed on a circuit board inside the display unit preserves data when the power is turned off. The life of the battery is about three years. When the battery voltage is low, battery NG appears at the self-test. When this happens, contact your dealer to request replacement of the battery. TYPE Lithium Battery CR2450-F2 ST2 Code Number 000-133-495

6.1 Checking

Regular maintenance is essential for good performance. Checking the items listed in the table below on a regular basis will keep the equipment in good shape for years to come. Item Cable run Action If conductors are exposed, replace cable. If loosened, tighten. If corroded, clean. If out of rating, correct problem.

Power cable, transducer cable plug Display unit ground Ship's mains voltage
6.2 Cleaning the Display Unit
Dust or dirt on the display unit should be removed with a soft cloth. If desired a water-moistened cloth may be used. Do not use chemical cleaners; they can remove paint and markings.

6.5 Troubleshooting

The table below provides simple troubleshooting procedures which you may follow to restore normal operation. If you cannot restore normal operation, contact your dealer.
SYMPTOM No picture; no reading measure
PROBABLE CAUSES Low power supply Fuse blown Power cable damaged
REMEDY Check the supply voltage. Replace the fuse. Check the cable and repair. Repair the cable. Tighten the connections. Make sure the maximum output power is selected. (See section 3.2 System Menu 1.) Increase the Gain by turning the GAIN control clockwise. Suspect muddy seabed. Remove marine life from the transducer when dry docked. Check the range scale setting. This is normal, it is not a sign of equipment trouble. Find cause of noise. Relocate the transducer if noise persists. If more than one echo sounder is working on the ship, there is no ideal measure to cure the problem. Not an equipment problem. Not an equipment problem.
