How to measure range and bearing from the control unit (RCU-014)
Range and bearing can be measure using the EBL OFFSET key.
1. Press the EBL ON key to activate EBL1.
2. Place the cursor inside the operational display area, then press the EBL OFFSET
key. EBL1 moves to the cursor.
3. Place the cursor (EBL1 moves with the cursor) on a target of interest. (Shown as
"Target 1" in the above example), then press the EBL OFFSET key.
4. Rotate the EBL knob to move the EBL until it passes through another target of in-
terest. (Shown as "Target 2" in the above example).
5. Place the cursor on the [VRM1] box.
6. Rotate the VRM knob until the range marker on the EBL is on the inside edge of
Target 2. The readouts for EBL1 and VRM1, at the bottom of the screen, indicate
the bearing and range between the Target 1 and Target 2.
7. You can repeat the same procedure on third and fourth targets (shown as "Target
3" and "Target 4" in 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.
How to reset the EBL origin to the center of the screen
1. Place the cursor on the box for the EBL to reset, then left-click. The selected EBL
is now active and highlighted.

SOR] context menu appears.
3. Select [EBL OFFSET]. The cursor is now displayed with a red surround.
4. Left-click to return the EBL to the center of the display.
5. Right-click to deactivate the [EBL OFFSET] mode. The red surround on the cursor
