Chapter 5: Using the Radar 5-17
How do I create a VRM/EBL?
The first VRM/EBL will be placed at a location of 1/3 of the current range and 030°
relative to your boat’s head. If this setting is adjusted, the display will retain the
adjustments and use them when the VRM/EBL is next turned on.
To use VRMs/EBLs to tell you the range/bearing of a target:
1. Toggle VRM/EBL soft key to ON. The VRM/EBL will be shown on the radar picture
with your boat at its center.
2. ADJUST VRM and VRM are highlighted to indicate it can be adjusted.
3. Use the rotary control to adjust the VRM to the required size.
4. Press the rotary control or press ADJUST EBL. This will highlight the EBL.
5. Use the rotary control to place the EBL over the required target.
6. Press OK to remove the highlight and retain the adjustment.
The distance and bearing of the target is now shown in the ADJUST VRM and ADJUST
EBL soft key labels. You will be able to tell which way the target is traveling by watching
how it moves in relation to the EBL. If it continues traveling directly along the EBL, it
shows that it is on a possible collision course with your boat - take the appropriate
action.
To place a second VRM/EBL use the SET UP VRM/EBL 2 soft key and repeat steps 1 to 7
above. This VRM/EBL will be placed at a location of 2/3 of current range and a bearing
of 330°.
... Using floating VRMs/EBLs
You can use the VRM/EBL float function to measure the range and bearing between
any two points on the radar screen. This function allows you to move the VRM/EBL
away from your boats position and onto a target. You can then change the radius of
the VRM to determine the distance between two points and change the angle of the
EBL, relative to its new origin, to obtain the bearing.
How do I float a VRM/EBL?
1. Create the VRM/EBL as described previously.
2. Press FLOATING EBL. This will highlight the VRM/EBL.
3. Press ADJUST FLOAT. The cursor is positioned at the center.
4. To set the origin to a different position:
