the bottom signal goes deeper than the deep alarm’s setting.

of the screen. Finally, press
the key next to the "Accept"
label. The screen shown above appears.
The zone alarm’s bar appears on the right side of the screen. Adjustment
menus show in the middle of the screen. Press the up or down arrow keys
to move the
bottom
of the zone alarm bar up or down. To adjust the top of
the zone alarm bar, first press the key adjacent to the "Adjust Upper"
label. After setting the zone alarm bar, press the CLR key to erase the
menus and bar or wait a few seconds and they will automatically clear.
(You can turn the zone alarm’s bar on continuously. See the 2D View
Options section for more information.)
Setting the zone alarm automatically turns it on. To turn it off, press the
ALARM key, then press the key next to the zone alarm’s menu. This moves
