The depth alarms sound a
tone when the bottom signal
goes shallower than the shal-
low alarm’s setting or deeper
than the deep alarm’s setting.
For example, if you set the
shallow alarm to ten feet, the
alarm will sound a tone if the
bottom signal is less than ten
feet. It will continue to sound
until you mute it or the bottom
goes deeper than 10 feet. The
deep alarm works just oppo-
site. It sounds a warning tone
if the bottom depth goes
deeper than the alarm’s set-
ting. Both depth alarms work
only off the digital bottom
depth signals. No other tar-
gets will trip these alarms.
Both can be used at the same
time.
To set the depth alarms,
press the key adjacent to the
alarm you wish to set. In this
example, we will set and turn
on the shallow alarm. When
the X-70A 3D is turned on, the
shallow alarm is set to zero.
Pressing the key next to the
“Shal Alarm” menu moves the
check mark to the "SET" box.
This brings up the adjustment
menu, as shown above. Using
the numbered keys, enter the
depth for the shallow alarm. In
this example, we used 10 feet.
Press the key next to the “Ac-
cept” label. The screen returns to the alarm menu. The number you en-
tered shows on the shallow alarm’s menu. You’ll also notice that the check
mark in the shallow alarm’s menu has moved to the “ON” box. Setting an
alarm also turns it on. Press the CLR key to return to the sonar display.
Using our example, if the bottom signal goes lower than 10 feet, the shal-
