Push [ ] to select the illumination level. · Key illumination corresponds with [BRILL]/[ ] control. 9 4 BASIC OPERATION The following are typical basic operation examples, which may hinder radar reception (sea clutter, precipitation interference and echoes from other radar). I RAIN function This function eliminates reflection echoes from rain, snow, fog etc. · Rotate the control fully counterclockwise to deactivate the control function. · NOTE: DO NOT reduce the reflection echoes too much, otherwise you may miss weaker targets. Small echos Adjust RAIN control I SEA function This function serves to eliminate echoes from waves at close range. Reduce the receiver gain for close objects within a radius of 8 miles to eliminate sea clutter. · Rotate the control fully clockwise to activate the automatic control function. SEA indicator ( )appears in the upper left of the screen. WARNING: Echos from sea waves Adjust SEA control The [SEA]/[ ] control reduces the receiver sensitivity of objects within 8 miles. Therefore, caution and careful adjustment are necessary when using the [SEA]/[ ] control. Small objects may not be displayed on the screen when strong echoes from the rain or the island within 1 NM while automatic SEA function is activating. I OFF CENTER function The scanning area can be shifted in a desired direction and can be enlarged partially. This is useful when the Head-up* is selected and you want to enlarge the bow direction display, or, the center of the screen shifts in the direction of the intersection. · This function is available for 24NM or shorter range selection. *This function is not available in the TM screen. Normal screen With OFF CENTER ON q Push [Ù Ú ] to move the cursor where you want to shift the center of the screen. · Max. offsetting is up to 75% of the screen. w Push [ALM]/[ ] and [MODE]/[ ] simultaneously to shift the screen. e Push [ALM]/[ ] and [MODE]/[ ] simultaneously again to return to the normal screen. 10 BASIC OPERATION 4 I IR function Radar interference may appear when another ship's radar is operating on the same frequency band in close proximity. · "SAVE" and standby time appear in the top of the screen and the standby time is counted down. GPS COMPASS GPS COMPASS EBL1 EBL2 MOB CURS VRM1 VRM2 34° 37. 72N 1 3 5 ° 3 4 . 4 2 E EBL1 EBL2 MOB CURS VRM1 VRM2 34° 37. 72N 1 3 5 ° 3 4 . 4 2 E Push and hold [TX] for 1 sec. to turn the SAVE function on. Scan and STBY alternates e After the selected standby time elapses, transmission and rotation restart. r Push [TX (SAVE)]/[ ] to cancel the power save function. · The save indicator turns OFF. NOTE: When you use the power save function together with the alarm function, the CRT display is turned OFF until an object enters the programmed alarm zone, therefore, more power saving is possible. 17) 12 BASIC OPERATION 4 I Ship speed indication When the ship speed data with NMEA 0183 format is applied, the radar can display the ship speed. Knots (KT) or kilometers/hour (KM/h) are automatically selected in the normal screen (p. 4) by selecting nautical miles (NM) or kilometers (KM) respectively. q Push [MENU]/[ ] several times to call up the FUNCTION menu. w Push [Ú] until the "DIST UNIT" section becomes highlighted. e Push [ ] to turn the ship speed indication to NM or KM. r Push [MENU]/[ ] several times to exit the menu display or push [Ú] once to proceed to the position display setting. I Long pulse function To magnify the blips for easier viewing of small targets, the long pulse and echo stretch (p. When the long pulse is used in the 3/4 to 2 NM range, this function magnifies target echoes to the backward direction of the target. [. . . ] · If the SHM signal is interrupted for more than 15 sec. , an alarm tone is emitted. · If the position signal is interrupted for more than 15 sec. , an alarm tone is emitted. · The system cable may not be connected properly. *1 Push any key to cancel the error message and beep tone. Turn the power OFF, then check the external data cable connection. [. . . ]
