3.6 Use of Function Keys
3.6.1 Overview
The purpose of function keys is to always get the best radar images by :
- Storing and using complex radar signal processing settings in the optimum status by usage,
and
- Calling optimum signal processing settings for the sea conditions, weather, ship dimensions,
and the like.
Four function key modes are available.
The four modes mean that four different signal processing and radar settings can be stored
separately.
In other words, as long as signal processing setting suitable for short-range observation, optimum
signal processing for trawling, and trail setting have been registered, each setting can be selected
instantaneously by simply pressing the [FUNC] key to switch to the mode.
As explained in the above, you can register any setting for functions 1 to 4. The following are 13
typical signal settings that can be selected:
OFF : Off
STAND : Setting for standard situation
COAST : Setting for coast navigation
DEEPSEA : Setting for deep-sea navigation
FISHNET : Setting for fish net detection
STORM : Setting for storm weather
CALM : Setting for calm weather
RAIN : Setting for rain/snow
BIRD : Setting for bird detection
LONG : Setting for long-range detection
BUOY : Setting for buoy detection
USER1 : User setting 1 (Used for setting not included in the 11 settings above)
USER2 : User setting 2 (Used for setting not included in the 11 settings above)
The signal processing settings above are defined in accordance with the titles. Users can make
further detailed settings meeting their needs.
Functions 1 to 4 are factory-set to the titles and signal processing settings as follows:
FUNC1 : COAST
FUNC2 : DEEPSEA
FUNC3 : FISHNET
FUNC4 : RAIN
