Auto sensitivity

there is no number next to the bar graph, this tells you that the Sidelooker is being adjusted.

From the menu item for the range setting, press the V arrow of the Page Control Pad. The next menu item will allow you to set the sensitivity. See Fig. 4-3. Use the < and > arrows of the Page Control Pad to select Auto or Manual sensitivity.

Auto sensitivity

The FishFinder can be set to select the sensitivity by itself, automatically. The unit chooses the sensitivity setting which will detect fish, but will also show a minimum of background noise. If the amount of background noise changes (due to changing depth or water conditions), the FishFinder will change the sensitivity to adjust. (You can still adjust the sensitivity of the unit while it is using Auto sensitivity. Once you select Auto sensitivity using the menu item shown in Fig. 4-3, use the V arrow of the Page Control Pad to go to the next line. Use the < and > arrows of the Page Control Pad to fine-tune the sensitivity setting. To reset the Auto sensitivity to its normal or default setting, switch the sensitivity from Auto to Man and back to Auto again. It will also be reset when the FishFinder is turned off and back on again.

Manual sensitivity

You can also set the sensitivity manually. If the amount of background noise changes, the FishFinder will not adjust for this. If you choose Manual sensitivity, press the V arrow of the Page Control Pad to go to the next line. Use the < and > arrows of the Page Control Pad to move the dark bar on the display. Making the bar longer increases the sensitivity.

If you are done with your setup changes, press the CLEAR button to go back to the normal display. To select the next menu item, press the V arrow of the Page Control Pad.
