Alarms

This sounder has five alarms: fish alarm, bottom alarm, bottom fish alarm, water
temperature alarm and vertical temperature alarm. When the bottom echo or fish echo
comes into the alarm range or the water temperature is within or out of the range of the
temperature value set, the equipment generates audio and visual alarms to alert you. If
"Alarm" is enabled on the Status window, the offending alarm is shown in red, in reverse
video. To silence the audio alarm, press any function key. The audio and video alarms will
be released anytime the alarm conditions are violated.

Alarm description

Bottom alarm
The bottom alarm alerts you when the bottom echo enters the alarm area. When the alarm
is violated, the audio alarm sounds and the visual alarm "BOTTOM" appears (flashing) in
red reverse video.
Fish alarm
The fish alarm alerts you when fish echoes enter into the set alarm range. When the alarm
is violated, the audio alarm sounds and the visual alarm "FISH" appears (flashing) in red
reverse video. This alarm is useful when targeting a specific fish specie, since each fish
specie is known to inhabit certain depths.
Bottom fish alarm
The bottom-fish alarm sounds when a fish echo is within a predetermined distance from the
bottom. When the alarm is violated, the audio alarm sounds and the visual alarm "BL-FISH"
appears (flashing) in red reverse video.
Temp alarm (requires temperature sensor)
There are two types of temperature alarms: within range and out of range. When the alarm
is violated, the audio alarm sounds and the visual alarm "TEMP" appears (flashing) in red
reverse video. The temperature alarm may be used to target specific fish species, as each
fish specie is know to inhabit certain temperature ranges.
V-temp alarm (requires net sonde or trawl sonar)
There are two types of v-temp alarms: within range and out of range. When the alarm is
violated, the audio alarm sounds and the visual alarm "V-TEMP" appears (flashing) in red
reverse video.
