The sounder section has five conditions which generate visual and aural alarms:
bottom alarm, fish alarm (bottom lock), fish alarm (normal) and water

the alarm icon is red when an alarm setting is violated, and changes to
background color when the [CLEAR] key or CLEAR ALARM soft key is pressed.
The color does not change when another alarm is violated.
You may set up the sounder alarms on the ALARM menu, which may be
