Turn off the hull unit before using the hand crank.

CAUTION

Do not exceed 18 knots with the trans- ducer lowered and do not exceed 16 knots when lowering or raising the transducer.

The transducer may become damaged.

Turn off the hull unit before using the hand crank.

Bodily injury may result if the power is not turned off.

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 iinside the ship.

WARNING LABEL

A warning label is attached to all units of the system. Do not remove any label. If a label is missing or damaged, contact a FURUNO agent or dealer about replacement.
