1. OPERATIONAL OVERVIEW
4. With the cursor in the operational display area, press the ADJUST knob. EBL1
moves to the cursor location.
5. Place the offset EBL on the target of interest (Target 1), then push the ADJUST
knob.
6. Press the right button to deactivate the [EBL OFFSET] mode. The red surround
on the cursor disappears.
7. Place the cursor on the EBL1 box, then rotate the ADJUST knob until EBL1 inter-
sects the secondary target (Target 2 in the example figure).
8. Place the cursor on the VRM1 box, then rotate the ADJUST knob until the range
marker on EBL1 aligns with 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.
9. You can repeat the same procedure on third and fourth targets (shown as "Target
3" and "Target 4" in the above example) by using EBL2 and VRM2.
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 measure range and bearing from the control unit
Range and bearing can be measure using the function keys. This requires at one of
the function keys (F1, F2 or F3) to be assigned the [EBL OFFSET] function.
This procedure uses [EBL1] and [VRM1] as an example, with F1 assigned as the [EBL
OFFSET] function key.
1. Press the EBL key to activate EBL1.
2. Place the cursor inside the operational display area, then press the F1 knob. 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 ADJUST knob.
4. Press the right button.
5. Place the cursor on the [EBL1] box.
6. Rotate the ADJUST knob to move the EBL until it passes through another target
of interest. (Shown as "Target 2" in the above example).
7. Press the VRM key, to activate VRM1.
8. Rotate the ADJUST 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, indi-
cate the bearing and range between the Target 1 and Target 2.
9. 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.
