455 kHz Balance

(Advanced; 575 Fishfinders only)

455 kHz Balance adjusts the sensitivity of the 455 kHz beam and is only available on 575 models. Increasing the sensitivity will display additional weak returns and decreasing the sensitivity will display fewer weak returns. The 455 kHz Balance menu choice is only available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).

NOTE: 455 kHz Balance is particularly useful for adjusting the sensitivity of the 455 kHz sonar returns in the Side Beam View. The 455 kHz sensitivity can be adjusted without affecting the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window.

To change the 455 kHz Balance setting:

1.Make sure you have selected Advanced Mode, then highlight 455kHz Balance on the Sonar Main Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the 455 kHz Balance. (-10 to +10, Default = 0)
