Inserting a Chart Card

Your unit reads FURUNO and Nav-Charts (NAVIONICS), or C-MAP chart cards, depending on its specifications. Insert the appropriate chart card for your area as follows: 1. Open the chart card slot lid.

Chart slot

Display unit 2. Insert desired chart card groove side up. 3. Close the lid to protect the chart drive. Note 1: Do not insert or remove the chart card while turning power on. This may cause the equipment to freeze. Note 2: Do not remove a card while the chart is being drawn. This may cause the equipment to freeze. Note 3: A card remover is supplied to ease removal of chart cards. Attach the card remover to the right-hand side hole on the card and pull to remove card. You can leave the card remover attached to the card while the card is in the card slot - push the card remover leftward until it contacts the recessed area in the card. Note 4: For multiple display units, do not use the same chart card type in more than one display unit.

Turning the Unit On/Off

Press the [POWER/BRILL] key to turn the unit on. A beep sounds and the equipment proceeds in the sequence shown below, displaying the product information screen, startup test results and the chart usage disclaimer, in that order. The startup test checks the ROM, RAM, internal battery and backup data for proper operation, displaying the results for each as OK or NG (No Good). If NG appears, an appropriate message appears on the screen. For any NG, try to press any key to go to the chart disclaimer screen, then perform the diagnostic test referring to the paragraph 7.5 Diagnostics.

Data Boxes
Data boxes, providing navigation data, may be shown on any full-screen display. Up to six data boxes (two in case of large characters) may be shown, and the default data boxes are position (in latitude and longitude), course over ground, speed over ground, trip log and cursor position. The user may choose which data to display, where to locate it, and show or hide it as desired. In addition, data boxes may be set independently for each display mode (radar, plotter, sounder). For how to select data for the data boxes, see paragraph 5.5 Data Boxes Setup.

North Heading Line

North-up presentation mode True motion Fixed radar targets maintain a constant position on the screen, while your own ship moves across the radar image at the correct speed and heading. A map-like image is displayed, with all moving vessels traveling in true perspective to each other and to fixed landmasses. As your ships position approaches the edge of the screen, the radar display is automatically reset to reveal the area ahead of your ship. You can manually reset your ships position at any time by pressing the RADAR DISPLAY soft key followed by the SHIFT soft key.

The procedure below may be used to check if a radar target is on a collision course with your vessel. 1. Press the [EBL/VRM] key to show the EBL/VRM soft keys. 2. Press the EBL1 ON soft key to turn on the EBL1. 3. Press the OFFSET soft key. The origin of EBL1 moves to the cursor position and an X appears at the cursor position. 4. Use the cursor pad to place the cursor on the radar target which looks like it might be on a collision course with own ship. 5. Push the [ENTER] knob to fix the origin position. 6. After waiting for a few minutes (at least three minutes), rotate the [ENTER] knob so the EBL bisects the target at the new position. If the target tracks along the EBL towards the center of the display (your ships position), the target may be on a collision course. 7. To cancel the offset EBL, press the OFFSET soft key.

This section shows you how to get to a desired destination by quick points, waypoints, port services and routes. Note: When the plotter data is received from other NavNet unit connected, reciprocal setting and canceling of destination is available by using ZDA sentenceReferring to 6.5 Outputting Data Through the Network.

3.10.1

Navigating to a quick point
The quick point feature allows you to navigate to point(s) without retaining the data indefinitely in your units memory. Selecting quick point entry method You need to tell your unit how to set the quick point: 1POINT, 35POINTS (up to 35 points) or 35PTS/PORT SVC. (For how to navigate to points/port services see 3.10.3 Navigating to ports, port services on page 3-47.) 1. Press the [MENU] key. 2. Press the PLOTTER SETUP soft key. 3. Use the cursor pad to select SET GOTO METHOD and press the EDIT soft key.

GOTO METHOD

1POINT 35POINTS 35PTS/PORT SVC
Goto method window 4. Use the cursor pad to select method desired. 5. Press the ENTER soft key. 6. Press the [MENU] key to close the menu. Navigating to a single quick point 1. Place the cursor on an existing waypoint (GOTO WPT soft key appears) or a new location (GOTO CURSOR soft key appears). 2. Select 1 POINT following the procedure in the above paragraph. 3. Depending on the selection you made at step 1 press GOTO CURSOR or GOTO WPT soft key. A solid line (light-blue on the MODEL1722C/1723C series) with arrows connects between own ship and destination, which is marked as QP<01> for cursor-selected location or waypoint name in case of waypoint. Arrows on the line show the direction to follow to get to the point. Range and bearing from own ship to the destination appear at the top of screen. The quick point is saved to the waypoint list as waypoint QP01.

Navigating to multiple quick points 1. Select 35 POINTS following the procedure in Selecting quick point entry method on the previous page. 2. Press the GOTO soft key. 3. Place the cursor on an existing waypoint (SELECT WPT soft key appears) or a new location (ADD QP soft key appears). 4. Depending on the action taken at step 3 press the SELECT WPT or ADD QP soft key. QP<01> appears at the cursor location if a quick point is selected. 5. Repeat steps 3 and 4 to complete the route. To erase last-entered quick point (waypoint), press the ERASE LST QP (ERASE LST WP) soft key. 6. Push the [ENTER] knob to finish. A solid line runs between own ship and first waypoint and a dashed line between other waypoints. (For the MODEL1722C/1723C series, those lines are colored light-blue and green, respectively.) Quick points are numbered in sequential order from QP<01> and are saved to the waypoint list. Range and bearing from own ship to the first destination appear at the top of screen. The quick points are saved as a route, under the name Q>RTE (Quick Route).
