Turning the 957
on and off
To turn on the 957, briefly press the PWR key. The 957 emits
several short beeps as it displays the START-UP screen, then the
957 performs a series of self-tests to check its critical
components and functions.
Next, a message is shown as a reminder against relying on the
957’s chart cartography as the only means of safe navigation.
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.
To identify the cartridge inside the 957, press the CHART
SETUP menu key to the right of the CHART screen to display
the CHART STATUS screen (the cartridge door must be fully
closed and latched to display this information):
NOTE:
A brief warm-up period may be required for the
display screen to reach its full intensity.
