CAUTION

Internal inspection and maintenance must be conducted by our special maintenance

personnel, otherwise fire or an electric shock may occur.

Ask our sales department, nearest office or your local distributor for internal inspection

and maintenance.

Be sure to turn the main power source off before maintenance, otherwise an electric shock

may occur.

CAUTION

Do not use any organic solvent such as thinner or benzine when cleaning the surface.

Otherwise the surface coating may be damaged. For cleaning of the surface, remove dirt

and dust and wipe it with a clean, dry cloth.

Maintenance as described below is required for keeping the radar in a good condition. Since appropriate

maintenance reduces failure, it is recommended to maintain the radar regularly.

7.1.1 Cleaning

7.1.1.1 Cleaning of the Radar

Clear the radar body of dust, soil or seawater as much as possible with a dry cloth. In particular, completely

clean the air duct using a brush so as to allow sufficient air to go through it.

7.1.1.2 Cleaning of the ATA

When sea water of fresh water is sprinkled on this equipment, wipe it immediately.

It might cause a fault and an incorrect operation.

Softly wipe the dirt of this equipment by soaking a detergent in a soft cloth in such a degree that the detergent

cannot be dropped.
