control knob and read the bearing. Then, the
display setting for EBL1 will be completed either
(a)with the EBL1 display still on the screen if the
"ENT" key is pressed, or (b)without the EBL1
display if the "MENU" key is pressed. (c)Pressing
another function key will lead to the function of
that key with the EBL1 display still on the screen.

and "measuring the distance(EBL2)", and place the EBL2 on another echo.
EBL2 is displayed on the screen based on the placed fixed cross cursor.
" 2 xx. xxφ" which is displayed at the lower right will be the angle between the two
points.
Note: The displayed EBL angle is relative to heading or true to north, depends on the setting
of "EBL BRG" in the "SETUP" menu.
5.5.1.7 Erasing heading marker temporarily (HDG OFF)
(1) Use the up-down cursor key to select HDG OFF
from among the pulled down and displayed items.
(2) Press the “ENT” key. The heading marker is not

Up/Down → ENT ------------ The heading marker is not displayed as long as you hold “ENT” key down.
(Select HDG OFF)
5.5.1.8 Using parallel cursors (///CSR)
Normally EBL is used to measure the exact bearing from the position of your ship to a
target. However, you can also use parallel cursors.
