Each time you turn off or on data recording, either a new file
opens or data appends to a particular file. See “Always Append to
the File parameter” on page 2-22 and “Files Creation Mode
parameter” on page 2-22 for information on setting this function.
• Pressing and holding the FN key for more than five and less than
eight seconds will turn the baud rate of serial port A to 9600.
After about five seconds of pressing the FN key, the REC LED
becomes red. Release the FN key while the REC LED is red
(during the next three seconds).
Pressing and holding the FN key for more than eight seconds has
no impact.
• After loading new firmware or clearing the receiver’s NVRAM,
the receiver checks its internal file system.
During this operation, the REC LED flashes orange, and the file
system is not accessible for CDU (control display unit)
applications or for data recording. This operation may require
from fractions of a second to several minutes, depending on the
circumstances and the amount of internal memory.
