Note: Each target objective defines a combina- tion of several radar settings for achieving opti- mum setup for that particular objective. Therefore, adjustment of radar settings through the FUNC menu is not necessary. If you acci- dentally change the settings, default settings can be restored by reselecting the target objective.

Turning on a function

Press the FUNCTION key to display function number desired (at bottom left corner on the dis- play.)

Note: When the main menu displays FUNC KEY*, this means no function is active and the FUNCTION key is inoperative. To select a func- tion, erase the menu and press the FUNCTION key.

1.23 Own Ship Speed

Ship’s speed can be entered manually or auto- matically (by speed log or radionav equipment). Own ship's speed is required for TM and display of vectors, E-plot, etc. The True Motion display works on a ship speed entered manually or auto- matically.

1)Press the MENU key and select the INITIAL menu.

2)Press the ENTER/SELECT key.

3)Select SPD MODE and press the ENTER/ SELECT key.

4)Select LOG or NAV and press the ENTER/ SELECT key.

Note: If no speed is input for 3 minutes at below

0.1knots, the radar regards this a log failure and displays SYSTEM FAIL LOG.
