1.32 Function Keys

The function keys work similar to the auto- matic dialing feature on a telephone, playing back control settings just as they were regis- tered. Instead of manually adjusting controls to set up for a particular condition, for ex- ample, navigation in a harbor, you can have a function key do it for you.

Each function key can be assigned a combi- nation of particular radar settings that will be most suited to a specPic navigation purpose, and an adhesive-backed label (such as OCEAN, COAST) is usually attached to the keytop for easy identification of the assigned purpose.

Presetting the function keys

The radar’s internal computer offers several navigation setups as outlined in the table on the next page. For instance, you might want to select RAIN as the objective of a function key. Then, when you press that function key the radar will be instantly set up to operate under heavy rain conditions.

Each setup option defines a combination of several radar settings for achieving optimum setup for a particular navigating situation. Those involved are interference rejector, echo stretch, echo average, automatic anti-clutter, noise rejector, video contrast, and enhanced video.
