1. OPERATION 1.20 Guard Alarm How guard zone type is determined The guard alarm allows the operator to set the desired range and bearing for a guard zone. When ships, islands, landmasses, etc. violate the guard zone, the audio alarm sounds to call your attention. The alarm will sound on targets entering or exiting the zone depending on zone status after the alarm has been set.
1. OPERATION 1.21 Watchman Watchman transmits the radar for one minute to check if a target has entered or exited the guard zone from the previous transmission. If no change is found, the radar goes into standby for the number of minutes set for the watchman feature. If change is found, the audio alarm sounds, watchman is canceled and the radar transmits. This feature is useful for extending the life of the magnetron.
1. OPERATION 1.23 PROG Key The [PROG] key acts as a menu shortcut key. You may use any User menu item except “SYSTEM MENU.” Using the PROG key 1. Press the [PROG] key. The options window corresponding to the item programmed appears. In the example below the echo stretch options window is shown. 1.24 Outputting Target Position to a Plotter If the radar is interfaced with a plotter, you can output target position to the plotter, and show that position on the plotter’s screen with the target mark (X).
1. OPERATION 1.25 Turning Navigation Data On/Off Navigation data appears on the bottom half of the screen as in the illustration below. You may turn the navigation data display on or off as shown below. 3. Press the [MENU/ESC] key to close the window. 4. Press the cursor pad to display the nav data setup window.

1. OPERATION 1.27 System Menu System menu description The System menu mainly contains items which once set do not require frequent adjustment. You may display this menu by choosing “SYSTEM MENU” from page 3 of the User menu and then pressing ►.
1. OPERATION SHIFT MODE: Own ship position, or sweep origin, can be displaced manually or automatically. For automatic displacement, the amount of shift is calculated with ship speed, and the amount is limited to 60% of the range in use. For example, if the “Auto Shift Speed” setting is 15 knots and the ship is running at 10 knots, the amount of shift will be about 40%. The formula for determining shift amount is as below. Requires speed data.
2. MAINTENANCE, TROUBLESHOOTING WARNING NOTICE ELECTRICAL SHOCK HAZARD Do not open the equipment. Only qualified personnel should work inside the equipment. Do not apply paint, anti-corrosive sealant or contact spray to coating or plastic parts of the equipment. Those items contain organic solvents that can damage coating and plastic parts, especially plastic connectors. 2.1 Maintenance Regular maintenance is important for good performance.
2. MAINTENANCE, TROUBLESHOOTING 2.2 Replacing the Fuse The fuse (5 A) in the power cable protects the equipment against reverse polarity of ship’s mains, overcurrent, and equipment fault. If the fuse blows, find the cause before replacing it. CAUTION Use the proper fuse. Use of a wrong fuse may cause serious damage to the equipment and void the warranty. 2.3 Troubleshooting The table below provides simple troubleshooting procedures which the user can follow to restore normal operation.
2. MAINTENANCE, TROUBLESHOOTING 2.4 Diagnostics Interpreting display unit test results If you feel that your unit is not working properly, conduct the appropriate diagnostic test, display unit or antenna unit, to find the possible cause. If you cannot restore normal operation, contact your dealer for advice. Item ROM, RAM Results OK: Normal NG: No Good Test connector required to test. Normally, “01” is displayed.
