CAUTION

Do not exceed 18 knots when operating the equipment and do not exceed 16 knots when lowering or raising the transducer.

The transducer may become damaged.

The zinc block attached near the transducer must be replaced yearly.

The junction between the transducer and main shaft may corrode, which can result in loss of the transducer or water leakage inside the ship.

Do not use the equipment for other than its intended purpose.

Use of the equipment as a stepping stool, for example, may result in personal injury or equipment damage.

Replace the monitor when the picture becomes difficult to see.

The average life of the monitor is about 10 years. Replace it when the picture be- comes difficult to see, to protect vision.

A warning label is attached to the equip- ment. Do not remove the label. If the label becomes soiled or illegible, contact a FURUNO agent or dealer.
