FOREWORD A Word to the Owner of the FR-1908V-BB/FR-1918V-BB Radar Congratulations on your choice of the FR-1908V-BB/FR-1918V-BB Radar. Please carefully read the safety information and operating instructions set forth in this manual be- fore attempting to operate the equipment and conduct any maintenance. Your radar set will per- form to the utmost of its ability only if it is operated and maintained in accordance with the correct procedures. Features The FR-1908V-BB/FR-1918V-BB consists of an antenna unit, processor unit, and control unit and is designed to meet the requirements of navigation radar used on inland waterways. Radar targets are displayed on a vertically oriented SXGA display, in a single color or gradations of green or cyan according to echo strength. A 17 to 19 inch display with SXGA (or equivalent) resolution is recommended. Larger displays may result in dim images. Further, if the aspect ratio of the display is different from SXGA, images may be distorted. Also, displays larger than 19 inches and having the same aspect ratio as SXGA may have a “blank” display area at the top and bottom of the screen. Following are the main features. • Displays inland AIS targets • Easy switching between River and Sea modes • Automatic capture of the radar display • Alarm history with Alarm log • Graph displays: ROT, Rudder and AutoPilot • TT (Track target) function to watch other ships’ movement • Large capacity memory - Mark/Line: max. 5,000 points, TT: 100 targets, AIS: 300 targets Program No. 0359451-01.** ** denotes minor modifications. viii

1. OPERATION 1.3 How to Transmit To transmit, press the STBY/TX key while [STBY] is displayed. Radar echoes are dis- played on the screen with the previously used settings of range. Each press of the STBY/TX key switches between stand-by and transmit (You can also switch between stand-by and transmission by clicking the [STBY/TX] indication.). The antenna is stopped in stand-by, and rotates in transmission. The magnetron in the antenna unit generates the radar pulses and decays over time. To extend the life of the magnetron, keep the radar in stand-by when its use is not re- quired. 1.4 Radar Display Indications The illustration below shows all the icons and symbols (both in the [RIVER] and [SEA] modes) that may appear on the display.

ROT RO SEA RUDDER RIVER RUDDE 2/ 0.4NM Click the operation 1.6/ 0.4SM HEAD-UP HDG HEAD-UP HDG mode icon OFFCENT OFF OFFCENT OFF STBY S STBY S Note 1: To enable switching of the operation mode, the [OPERATION TYPE] setting, in the [SERVICE MENU], must be set to [RIVER-SEA]. See your dealer. Note 2: To change the operation mode ([RIVER] or [SEA]), go to [STBY] once to se- lect the operation mode then go to [TX] mode. The following items are set according to the operation mode. • Orientation mode • Range • Units • Screen size (River mode: circle* only, Sea mode: circle* and wide*) *: See section 1.9. 1-12

1. OPERATION 1.10.2 Orientation mode Relative motion (RM) In relative motion, own ship position is stationary on the screen to observe relative mo- tion of surrounding targets. • HEAD UP The head-up mode is a display in which the line North marker Heading connecting own ship and the top of the display line indicates own ship's heading. The target pips are painted at their measured distances and in their directions relative to own ship's head- ing.The short line on the bearing scale is the north marker, which indicates heading sensor north. • HEAD UP (TB) Radar echoes are shown in the same way as in the head-up mode. The difference from normal head-up presentation lies in the orientation of the bearing scale. The bearing scale rotates in accordance with the heading sensor signal, enabling you to know own ship's heading at a glance. This mode is available when the radar is interfaced with a gyro heading sensor. If the gyro heading sensor fails, the bearing scale returns to the state of head-up mode. • STERN UP A display without azimuth stabilization in which the line that connects the center with the top of the display indicates your stern. • NORTH UP The north-up mode paints target pips at their North mark measured distances and in their true (heading sensor) directions from own ship, north bearing is fixed at the top of the screen. The heading line changes its direction according to the Heading ship's heading. This mode requires heading line signal. If the compass fails, the orientation mode changes to head-up and the north marker dis- appears. • COURSE UP The course-up mode is an azimuth stabilized North mark display in which a line connecting the center Heading with the top of the display indicates own ship's line intended course (namely, own ship's previous heading just before this mode has been select- ed).Target pips are painted at their measured distances and in their directions relative to the intended course, which is maintained at the 0- degree position. The heading line moves in ac- cordance with ship's yawing and course change. 1-13

1. OPERATION True motion (TM) • NORTH UP Ground (or water mass) is stabilized with compass and speed inputs. Your ship and other objects in motion move with their true courses and speed. • COURSE UP Own ship and other moving objects move in North mark accordance with their true courses and speed. In ground stabilized TM, all fixed tar- gets, such as landmasses, appear as sta- Heading tionary echoes. In the sea stabilized TM line without set and drift inputs, the landmass can move on the screen.
