• Pressing the FN key for more than one and less than five seconds will start/stop data recording.
During data recording the REC LED is green or orange. If the REC LED is red, the receiver has
run out of memory, has a hardware problem, or contains an improper OAF.
• The REC LED blinks green or orange each time data is written to the internal receiver's memory.
You set the data recording time interval using TriVU Software. See TriVU Software Manual 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.
• Pressing 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 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 mem-
ory.
