Status LED
• When the receiver is on and no satellites are tracked, the STAT LED
will blink red.
• When satellites are tracked, the STAT LED will produce one blink for
each tracked satellite (green for GPS, orange for GLONASS).
FN Key and REC LED
• Pressing the FN key for less than one second switches the receiver
between different information modes (normal and extended
information), or between static and dynamic post-processing modes,
depending on the receiver's configuration.
During the first second of pressing the FN key, the REC LED is orange.
• 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 (see “Option
Authorized File (OAF)” on page 1-15 for more information on OAFs).
• 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 PCView. See “Recording
Interval parameter” on page 2-26 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 2-26 and “Files Creation Mode parameter” on
page 2-27 for information on setting this function.
• 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.
