Raychart 425 Chartplotter Owner's Handbook Document # 81172_3 Date: March 2002 Raychart 425 Chartplotter iii Raychart 425 Chartplotter Owner's Handbook SAFETY NOTICES CAUTION: HIGH VOLTAGE The display unit contains high voltages. Adjustments require specialized service procedures and tools available only to qualified service technicians ­ there are no user serviceable parts or adjustments. The operator should never remove the display unit cover or attempt to service the equipment. CAUTION: NAVIGATIONAL AID This device is only an aid to navigation. [. . . ] Bearing, Range and Cross Track Error are calculated for the target waypoint in the same manner as for any other Goto or Follow function. On arrival, the arrival alarm is sounded and the arrival pop-up box is displayed. To navigate directly to the nearest port or facility: 1. Press the GOTO key and select GOTO NEAREST to display the list. The list shows the eight nearest places where the selected facility exists, in order of distance. The bearing and range (in selected units) for each one is shown. Use trackpad up/down to select the required destination and press ENTER to start the GoTo, or CLEAR to cancel the operation. The operation is conducted in the same manner as for GOTO PORT above. Chapter 3: Operation 3-23 Stop Follow or Stop Goto To stop following the route or target point: 1. Either press the GOTO key or move the cursor over the target waypoint. Select the STOP GOTO or STOP FOLLOW function (Figure 3-38): STOP GOTO RESTART XTE D4689_1 STOP FOLLOW RESTART XTE WAYPOINT ADVANCE D4688_1 Figure 3-38: Stop Follow/Stop Goto Soft Keys The dotted line from the vessel to the target waypoint disappears. 3. 5 Changing the Display Mode Use the PAGE key to select the required display mode. Repeat presses of the PAGE key provide the following display modes: · · · · · · · Set Up functions (see Chapter 4) Course Deviation Indicator (CDI) Bearing & Distance Indication (BDI) Waypoint data Navigation data Time/Date data Return to Chart display Note: Press GOTO in any display mode to return to normal Chart display. To change the display mode: 1. Press the PAGE key to show the SET UP functions with SYSTEM SET UP highlighted (Figure 3-39): SYSTEM SETUP CHART SETUP TRACK SETUP GPS SETUP D4699_1 Figure 3-39: Setup Function Bar 2. Repeat Step 1 to cycle through each of the available display modes. Note: The Set Up Function Bar remains displayed in each display mode. To remove the Set Up Function Bar, press CLEAR. 3-24 Raychart 425 Chartplotter CDI Display The CDI display shows Cross Track Error (XTE) and distance to waypoint presented in a `runway' format (Figure 3-40): D4700_1 Figure 3-40: CDI Display The `runway' represents a 0. 3nm width with the vessel symbol shown at the bottom. Bearing to Waypoint, Distance to Waypoint, Time to Go (TTG), Course Over Ground (COG) and Speed Over Ground (SOG) are also shown. Time to Go is calculated on the basis of distance to destination and Speed Over Ground (SOG) towards the destination. At waypoint ranges greater than 4nm, the symbol remains at the top of the screen. As the waypoint range falls below 4nm, the symbol moves down the centre line. The checkered pattern moves down the screen to simulate movement when SOG is greater than 2 knots. The steering instruction is STEER STARBOARD if the XTE is 0. 01nm or more to port, STEER PORT if the XTE is 0. 01nm or more to starboard or ON COURSE if the XTE is less than 0. 01 on either side. If no GOTO or follow is in progress, the steering instruction is NO TARGET. The graphical XTE indication places arrows either side of the steering instruction and pointing towards it, dependent on the value of XTE. Chapter 3: Operation 3-25 The first arrow is shown when the XTE reaches 0. 01nm, the second at. 05nm and subsequently at 0. 1nm intervals. BDI Display The BDI display shows deviation from the bearing to waypoint and distance to waypoint. Cross track Error, Bearing to Waypoint, Distance to Waypoint, Time to Go, COG and SOG are also shown. Time To Go is calculated on the basis of distance to destination and velocity made good towards destination (Figure 3-41). D4701_1 Figure 3-41: BDI Display The line to the waypoint symbol is shown at an angle equal to the difference between the COG and the Bearing to Waypoint. The range scale automatically scales for distance.
