Alarms

This sounder has four alarms: 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 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.

Bottom alarm
The bottom alarm alerts you when the bottom echo enters the alarm area. The audio alarm
sounds and the visual alarm "BOTTOM" appears in red reverse video and flashes when the
bottom alarm is violated.
Fish alarm
The fish alarm alerts you when fish echoes enter into the set alarm range. The audio alarm
sounds and the visual alarm "FISH" appears in red reverse video and flashes when the
bottom alarm is violated. This alarm is useful when targeting a specific fish specie, since
each fish specie is known to inhabit certain depths.

bottom. The audio alarm sounds and the visual alarm "BL-FISH" appears in red reverse
video and flashes when the bottom fish alarm is violated.

There are two types of temperature alarms: within range and out of range. The audio alarm
sounds and the visual alarm "TEMP" appears in red reverse video and flashes when the
temperature alarm is violated. 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. The audio alarm
sounds and the visual alarm "V-TEMP" appears in red reverse video and flashes when the
