4.1.3  Using Electronic Bearing Lines (EBL1/EBL2) 
 
Electronic bearing lines (EBL) are indispensable to the measurement of bearings. 
Operators must be familiar with the operation of EBL beforehand. 
The system is equipped with two EBL. The bearing and starting point of an EBL can be operated 
separately from the other EBL. 
An intersection marker is displayed at the intersection point of the EBL and VRM of the same number. 
 
Intersection markers shown on EBL: 
: EBL1, VRM1 
 
 
: EBL2, VRM2 
 
 
 
 
EBL Bearing Display 
 
The bearing value of the current EBL1 or EBL2 on the PPI display is shown in the upper 
right of the radar display. The currently operable EBL1 or EBL2 is highlighted in the 
upper right of the display. 
 
 
 
Starting Point of EBL 
 
The starting point of the currently operating EBL can be switched from the center of the 
radar display to any offset position . The offset position of the EBL starting point can be 
fixed on the radar display or at the latitude and longitude. (The setting of the navigator is 
necessary for fixing the offset position at the latitude and longitude.)
