How to use the BERTHING STC function

The [BERTHING STC] function allows you to show the main bang echo, even with the
range set at 0.5 NM or less with AUTO SEA at maximum setting. This is particularly
useful when attempting to berth, as it gives a clearer view of the berthing area and your
ship's location.
To use the [BERTHING STC] function, follow the procedure below.
1. Open the menu.
2. Select [1 ECHO].
3. Select [0 NEXT]. The second page of
the [ECHO] menu appears.
4. Select [5 BERTHING STC].
5. Select [ON] to activate, or [OFF] to de-
activate, this function.
6. Close the menu.

How to Reduce Rain Clutter

Use the AUTO RAIN and A/C RAIN to reduced rain clutter. AUTO RAIN reduces rain
clutter in the picture and A/C RAIN reduces clutter picked up by the antenna.
Note 1: When both sea clutter and rain clutter are reduced, the sensitivity is de-
creased more than when only one is changed. For that reason adjust them carefully.
Note 2: The echo average function (see section 1.24) is useful for reducing reflections
from the sea surface. However, high-speed targets are harder to detect than station-
ary ones when echo average is active.
Place the cursor inside the
40
level indication, then spin the
scrollwheel.
