When using the Fish Alarm, use the A-GAIN-LEVEL feature to
control the size of the fish that the alarm sounds on. With a higher

LEVEL will have the same type of an effect on the Hard Bottom
Alarm as well.
Finally, press the Menu button two more times to exit. Change
to Mode 3 and then go back to Menu page 2.
