Your system reads NAVIONICS GOLD or 
C-MAP NT MAX charts, depending on the 
type of display unit you have. 
 
When you insert a suitable chart card in 
the slot and own ship is near any 
cartographic object, a chart appears. If a 
wrong card is inserted or a wrong chart 
scale is selected, landmasses will appear 
hollow. Chart icons appear at the top of the 
display to help you select a suitable chart 
scale. The table below shows the chart 
icons and their meanings. 

Chart scale is too large. 
Operate the RANGE key to 
adjust chart scale.   

Suitable chart scale is 
selected.
