6.If you want to adjust the gain threshold for the other frequency, repeat these steps.

7.When you are finished, select Return.

NOTE: If you're using fishing or cruising mode and adjust the gain yourself, the sounder automatically changes to manual mode.

18.5What is auto range and range shift?

Auto Range can be set On or Off:

•Auto Range On means that the sounder adjusts the range automatically so that the bottom is always shown. Auto Range On is recommended for normal cruising or fishing conditions. This is the default.

•Auto Range Off enables you to operate the range manually and to adjust the range and the range shift. The sounder shows only the range that you specify, for example, the 10 m of water between 15 and 25 m below your vessel.

Therefore, if your vessel moves into an area where the bottom is deeper than your specified range, the bottom won't be shown on your Sounder screen. Auto Range Off can be useful in areas where the depth of the bottom changes very rapidly, such as around pinnacles, because it avoids constant readjustments to your Sounder screen.

Range Shift defines the position of the specified range within the water column. You can use range shift to change the position of the range; for example, from 15 m through 25 m, to 5 m through 15 m.

18.6Turn the auto range on or off

You can toggle the Auto Range On or Off, to operate the range automatically or manually.

Auto Range On is the default. This always displays the bottom.

When the sounder Auto Mode (operating mode) is set to:

•Manual - Auto Range is automatically turned Off

•Fishing or Cruising - Auto Range is automatically turned On

To turn the auto range on or off:

1.Display the Sounder screen and the control panel. If you can't see the

Range, Zoom and Split button, select Return.

2.Select Range, Zoom and Split.

3.The Auto Range button shows the current setting. Select the button to toggle to the other setting. The new setting is shown immediately and stays until you change it again.

4.When you are finished, select Return.
