displayed as fish symbols. To turn the Fish I.D. feature off again, first press
the menu key. Next, press the key adjacent to the “Turn Fish I.D. Off” label.
The menu immediately disappears and the sonar screen returns.

the manual mode. If you turn the Fish I.D. feature on when the LMS-350A
is in manual, the micro-computer will turn the automatic feature on. If you
turn automatic off when the Fish I.D. feature is on, the Fish I.D. feature will
be turned off also.
