Introduction to the keypad
The keypad is used for direct user interface with the PI44
system, and allows you to control the functionality. Note that the
majority of the buttons are mainly used only during echo
sounder operations, and that some of them will only work when
they are enabled by a specific function.
EVENT: This button places a vertical marker on the
echo sounder depth display to identify an event.
MENU: This button turns the menu bar on and off. It
will also allow you to exit dialogues without applying
any changes.
ENT (Enter): This button allows you to apply the
changes you have made in a setup dialogue, or to select
a function from the menu. This button will also give
you access to the “Echo quick menu”, and it will open
the setup dialogue for the presentation in the active
window.
Selector pad: Use this button to navigate through
menus and dialogues. It moves the cursor horizontally
by pressing it on the left or right side, and vertically by
pressing it on its top or bottom.
-/+: These two button are used to select between
available values, scales and ranges. (-) reduces and (+)
increases the graduation.
GAIN: The two gain buttons are used to adjust the
receiver gain on the echo sounder.
STND (Standard): This button will activate an echo sounder
window in Standard mode. If you press this button while an
other window is active, the display switches to an echo sounder
page. If one of your other pages already contains a full screen
echo sounder, the PI44 will automatically change to this page,
and you must press the
PAGE button to return to your previous
page. If you do not have an echo sounder presentation among
your four presentation pages, the current presentation will be
replaced by the echo sounder presentation.
ADJ (Adjust): This button provides a direct access to the setup
parameters for the data in the active window. To exit the setup
without making changes, press the
MENU button.
VRM (Variable Range Marker): This button provides a
horizontal marker line on the echo sounder display. Use the
selector pad to alter the depth of the marker. The button will
only work if you have an echo sounder presentation on the
current page.
