SN3308 On-screen Messages
CHAPTER
Display Item Source Notes
CRC Self-Test Failed POST Program CRC is not the expected
value. The “CRC Self Test Failed”
message must not appear on
power-up if flight operations are
predicated on the use of the
SN3308 Navigational Display.
DEFAULT MEMORIES 1 TO 4 Pilot Appears when map memory
locations have been reset to their
default settings by pressing and
holding the "CLEAR" softkey while
in the map setup mode.
DEMO MODE: System This message appears when the
NOT FOR FLIGHT SN3308 has been placed in demo
mode for use with the Sandel
demonstrator box. In this mode,
the SN3308 does not respond
normally to signal inputs. To exit
demo mode, power up the
SN3308 while holding the [NAV],
[MAP] and [BRG] buttons
simultaneously.
EXT. SWITCH SET TO LORAN Pilot This message appears when
pressing the "NAV" switch on the
SN3308 when it is slaved to an
external loran/NAV switch/
annunciator panel. Instead of the
SN3308 NAV switch use the
external loran/NAV switch.
