1.33 Function Keys
The four function keys (#1-4) on the con-
trol panel work like the auto-dialing fea-
ture of a telephone, instantly calling out
desired settings to perform specially as-
signed functions. The function keys pro-
vide optimum radar settings for a specific
purpose with a single key operation.
Each function key can be assigned a com-
bination of particular radar settings that
will be most suited to your specific navi-
gating purpose, and an adhesive label
(such as BUOY, HARBOR, COAST or the
like) is usually attached to the key top for
easy identification of the assigned pur-
pose.
The individual function keys are preset,
or programmed, for the following pur-
poses by qualified service personnel at
the time of installation using the proce-
dures described in the succeeding para-
graphs:
Function key #1: Picture setup
Function keys #2 and #3: Picture setup
and specific
operation
Function key #4: Specific operation or
watch alarm

Suppose that you have been navigating
along a coast for hours and now you are
approaching a harbor, your final destina-
tion. You will have to adjust your radar to
change from the settings for coastal navi-
gation to those for harbor approach. Ev-
ery time your navigating environment or
task changes, you must adjust the radar,
which can be a nuisance in a busy situa-
tion. Instead of changing radar settings
case by case, it is possible to assign the
function keys to provide optimum settings
for often encountered situations.
The radar's internal computer offers sev-
eral picture setup options to be assigned
to each function key for your specific navi-
gating requirements. For instance, one of
the function keys may be assigned the
buoy detecting function and labeled
BUOY on the key top. If you press this
key, the radar will be instantly set for opti-
mum detection of navigation buoys and
similar objects and the label BUOY is
shown at the left margin of the screen. If
you re-press the same key, the radar re-
turns to the previous settings.
