3.13 Electronic Bearing Line (EBL) and
Variable Range Marker (VRM)
3.13.1 Electronic Bearing Line (EBL) and Variable
range marker (VRM)
The electronic bearing line (EBL) and the variable range marker (VRM) are the essential tools for
measuring bearings and ranges.
This equipment is equipped with two sets each for EBL (EBL1/EBL2) and VRM (VRM1/VRM2).
An intersecting point mark is displayed at the intersecting point between EBL and VRM.
By setting an intersecting point at any location, the bearing and range from the own ship’s position to
the location can be measured.
Two sets of EBL and VRM can be operated independently.
The first EBL and VRM are displayed in Long dashed line and the second EBL and VRM are displayed
in Short dashed line.
Memo
The line colours can be set on the dialogue that is displayed by selecting [Settings] - [Colour and
Brightness] on the menu.
