1.9 How to Shift the
Range
The basic range and range shift together give
you the means to select the depth you can
see on the screen. The basic range can be
thought of as providing a “window” into the
water column and range shifting as moving
the “window” to the desired depth.
Note: This function is inoperative when
[AUTO_R] (auto range mode indication) is
displayed.
The basic range can be shifted up or down in
the [Manual] mode as follows:
1. Open the menu, select the [Sounder]
menu and press the ENTER key.
2. Select [Shift] and press the ENTER key.
3. Set the amount of shift desired and press
the ENTER key. The step for the amount
of shift depends on setting range on the
[Range] sub menu in the [System] menu.
Below are the steps for feet and meters.
4. Press the MENU/ESC key twice to close
the window.
Note: Echoes may be lost if the amount of
shift is greater than actual depth.
1.10 Picture Advance
Speed
The picture advance speed determines how
quickly the vertical scan lines run across the
screen. When selecting a picture advance
speed, keep in mind that a fast advance
speed will expand the size of a school of fish
horizontally on the screen and a slow ad-
vance speed will contract the school. Use a
fast advance speed to observe a rugged bot-
tom, and use a slow advance speed to moni-
tor a smooth bottom.
“Window” can be
shifted up and
down to select
starting depth.
