2.9.3
Interference rejector
This control is similar to the interference rejector on echo sounders and radars. It is
effective for rejecting random noise and sea surface reflections in rough sea condi-
tions. Set it so that noise is just eliminated. Do not use an unnecessarily high setting
since it may also reject small, wanted echoes.
1. Press the
MENU/ESC
key to show the main menu.
2. Select [Picture Setting] then push the left-
click button.
3. Press the
H/V/S
key to select the [H1] or
[H2] tab.
4. Select [Int Reject] then push the left-click
button.
5. Select
S
or
T
then push the left-click but-
ton to change the setting. The setting
range is 0 to 3. The higher the setting, the greater the degree of interference re-
jection.

7. Long-press the
MENU/ESC
key to close all menus.

If the interference cannot be suppressed by the interference rejector or change in TX
interval, change the TX frequency from the [Frequency] menu.

key to close all menus.
Note:
In some cases, the TX frequency can not be changed because of operating
bandwidth. In this case the TX frequency setting is grayed.
