How to measure range and bearing
This procedure uses [EBL1] and [VRM1] as an example.
1. Press the CURSOR ON/OFF key when cursor is not shown on the screen.
2. Press the EBL key to activate EBL1.
3. Press the EBL OFFSET key to activate EBL offset function.
4. Move the cursor onto the target 1, then press the EBL OFFSET key.
EBL1 moves to the cursor.
5. Rotate the EBL key until the EBL line passes through target 2.
6. Rotate the VRM key until the range marker on the inside edge of target 2.
Read the EBL1 value and VRM1 value at the bottom on the screen.
7. You can repeat the same procedure on target 3 and target 4 of the above example
by using the No. 2 EBL and the No. 2 VRM.
Bearing is shown relative to own ship with suffix "R" or as a true bearing with suffix "T"
depending on EBL relative/true settings in the [EBL/VRM] menu.
