After the 958 displays its START-UP and SELF-TEST screens, a
message is shown to warn you against relying on the 958's
chart cartography as the only means of safe navigation.
Be extremely careful when navigating with electronic
charts. Although every effort has been made to ensure that the
data the 958 uses is as close as possible to paper charts,
errors and omissions are inevitable. The captain is responsible
for cross-checking the 958 against other sources of navigation
data.
To continue, accept the WARNING MESSAGE by pressing any
one of the five function keys (CHART, STAR, STEER, NAV
LOG, or WAYPTS/ROUTES) located below the display screen.
A 958 that has recently been used at or near that same loca-
tion will usually be ready to navigate within one minute.
Now you're ready to get underway with your 958!
CAUTION!
