Main Display
The initial display is divided into three parts: COMPUTER DISPLAY, LONG RANGE SCAN and SHORT RANGE SCAN.
They will all be described in detail, but briefly:
The COMPUTER DISPLAY gives various messages such as battle status, the type of shipping in view and so on.
The LONG RANGE SCAN gives a display of shipping positions relative to your own.
The SHORT RANGE SCAN gives a radar display of nearby shipping on the targetting computer. This can be looked on as an electronic periscope.
