When powering up the instrument, it will beep, the pointer will move to the top
of the display, and will show all the LCD segments for one second.
The display will then show the current heading if it is available.

These two displays will be available in all systems.

The Heading Display is the first display that is shown after power up. It simply
shows the present heading on the LCD, followed by a degrees sign, '°', and with
the left LCD arrow lit. The pointer also shows the present heading.
When using the HEADING push-button to cycle around the display menu the
Heading Mode is indicated by the symbol ' HdG', for heading.
