1.33 Function Keys

The four function keys (#1-4) on the control head serve for a macro function to instantly
select a combination of assigned functions or settings. The function keys provide optimum
radar settings for a specific purpose with a single key operation.

Each function key can be assigned a combination of particular radar settings that will be
most suited to your specific navigating 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 purpose.

The individual function keys are preset, or programmed, for the following purposes by
qualified service personnel at the time of installation using the procedures described in the
succeeding paragraphs:

Function keys #1, #2 and #3: Picture setup and specific operation

Function key #4: Specific operation or watch alarm

1.33.1 Picture setup

Suppose that you have been navigating along a coast for hours and now you are ap-
proaching a harbor, your final destination. You will have to adjust your radar to change
from the settings for coastal navigation to those for harbor approach. Every time your
navigating environment or task changes, you must adjust the radar, which can be a nui-
sance in a busy situation. 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 several picture setup options to be assigned to each
function key for your specific navigating 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 optimum 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 returns to the previous settings.
