Safety Instructions

WARNING

Do not open the equipment unless you are well familiar with electrical circuits.

ELECTRICAL Only qualified personnel SHOCK should work inside the HAZARD equipment.

Do not set the course changing speed too high.

The boat will be turned too sharply at the course change, which could create a very dangerous situation.

Do not use the autopilot in the following situation:

Harbor entrance or narrow channel Where vessels change course often, such as a cape or small island

Observe the following cautions when using the autopilot:

Maintain a vigilant watch

Watch for drifting of vessel

In an emergency, manually steer the vessel.

The autopilot cannot avoid vessels, etc. automatically.

Do not use the SIMULATION mode on the boat.

The rudder may move. This is special- purpose mode for technicians.

When connecting a geomagnetism detection type heading sensor, correct magnetic field deviation.

If an autopilot is used without the compens- ation, unexpected course change may occur.

WARNING

Do not use the ORBIT mode in rough sea.

Because the boat turns a 360-degree circle around the waypoint a large wave or strong wind can cause the boat to capsize.

For the figure eight mode, confirm that no objection is in the general vicinity of the waypoint.

The distance from the waypoint to the turning point depends on boat's speed.

Set the turn rate properly.

Setting the too high rate may cause sudden turn.

CAUTION

In case of power failure turn off the autopilot or manually steer the vessel.

Leaving the equipment in the AUTO or NAV mode during power failure will cause wear on the rudder mechanism.

Use the correct fuse.

Use of a wrong fuse can cause fire or damage the equipment.

WARNING LABEL

A warning label is attached to the processor unit. Do not remove the label. If the label is missing or damaged, contact your dealer about replacement.
