1.34 FUNCTION Key
The FUNCTION key works similar to the automatic dialing feature on a telephone, playing back
control settings just as they were registered. Instead of manually adjusting controls to set up for a
particular condition, for example, navigation in a harbor, you can have the [FUNCTION] key to do it
for you.
1.34.1 Presetting the FUNCTION key
The radar’s internal computer offers several navigation condition setups as outlined in the table
below. For instance, you might want to preset the level of parameters as HBR (Harbor) in FUNC
which you can later select among FUNC 1, 2 or 3 by pressing the [FUNCTION] key.
Each setup option defines a combination of several radar settings for achieving optimum setup for
a particular navigating situation. Those involved are echo average, interference rejector, echo
stretch, noise rejector, enhanced video, video contrast, automatic anti-clutter.
Adjusting these features on a function key menu changes the original function key settings. To
restore the original settings for a particular function key, it is necessary to display the relevant
function key menu and select appropriate menu options.
1. Press the [MENU] key (Ref. 1.33/1 – 2).
2. Press the [6] key twice to display the FUNC menu.
3. Press [4], [5] or [6] twice to select which function number to preset. For example, press the
[4] key to select FUNC 1.
