• The REC LED blinks green each time data is written to the
internal receiver’s memory.
You set the data recording time interval using PC-CDU.
See “Recording Interval parameter” on page 2-25 for
information on setting this function.
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 2-25 and “Files
Creation Mode parameter” on page 2-26 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.
