Memo 
About display in the chart 
Display in the chart can be considered as the composite of various layers. For example, STD 
(Standard: Standard display) is the composite of object layers for Base (Base display) and object 
layers for STD (Standard: Standard display).   
In addition to the object layers of the S-57/C-MAP charts themselves, own ship, user charts, event 
marks, EBL/VRM, radar images, etc. can be combined and then displayed. 
 
 
 
Note 
The initial chart screen status is "STD (Standard: Standard display)". For safe sailing, use the 
"STD (Standard: Standard display)" or "All (All display)", not the "Base (Base display)".
