Appendix 5 - Default and User Settings

 User settings

1 A facility should be provided to store and recall user-specific settings to suit the conditions at hand. At least two such configurations should be available to be stored for recall. Selection for recalling a stored configuration should be followed by an action to confirm the selection.

Default settings

2 A facility should be provided to apply a set of default settings to return the equipment to a known default state. The default settings are intended to provide a basic and minimal mode of operation for the system or equipment that can be built upon by the user.

3 Default settings are not intended to provide a redundant setting in the event of an equipment failure of loss of input.

ECDIS default settings
