Creating an ERBL
Each ERBL can be turned on or off independently. Previous settings are
maintained after they are switched off.
To turn on an ERBL do the following:
1. Click on ERBL 1 and/or ERBL 2 buttons on the lower toolbar to
access both ERBL popup windows. The ERBL 1 and ERBL 2
windows are opened on the display.
2. Left click on the EBL1 or EBL2 caption
button. The EBL button is highlighted bold
and the last bearing value entered is
displayed.
Alternatively, turn the EBL rotary control on
the control panel to switch on EBL1.
If no bearing value has been previously entered EBL 1 defaults to
5.0
o
starboard of ship’s heading and EBL 2 defaults to 355
o
starboard. The EBL 1 and 2 caption also displays the current EBL
reciprocal bearing in brackets.
3. On the display the EBL is shown as a dashed line at a bearing
angle dictated by the EBL readout. The range value of its
associated VRM is also shown, with a line drawn at the point where
the VRM intersects the EBL (see below), although the VRM is not
shown.
4. To turn the ERBL off, left click on the EBL button. The EBL lettering
and button return to normal, the bearing value and the VRM range
value are replaced by the
Off caption, and the ERBL is removed
from the chart display.
