Automatic Tilt - Furuno FSV-85 MARK-2 Operator's Manual

4.4.2

Automatic tilt

The AUTO TILT key automatically scans the tilt angle within the selected width. This
is useful when you want to find the center depth of a school of fish. Wide tilt angle is
activated from the [Auto Tilt] in the [Others] - [Display Setting] menu.
1. Press the AUTO TILT key to select auto tilt angle desired. Each time the key is
pressed the auto tilt angle changes in the following sequence.
2. If necessary operate the TILT control to change center tilt angle.

3. Auto tilt begins, with the tilt angle set with the TILT control as the center tilt angle.
For example, when the RANGE control, TILT control and AUTO TILT key are set to
800 m, 8° and width (1) respectively, the tilt angle changes at each transmission as
follows: 8°9°8°7°8°.
Note 1: The AUTO TILT key is inoperative when the target lock function is active or
is made active. Auto tilt is resumed once target lock is disabled.
Note 2: If the picture set with auto tilt is not visible, disable auto tilt and try again.
