The REC LED

(FUNCTION) button” on page 1-11 for more information on REC
LED behavior when using the FN button.
• Green blinks – each blink indicates that data is being written to
the SD/MMC card.
• Solid Orange – indicates the receiver is changing modes.
• Orange blinks – indicates that the receiver is checking its internal
file system (after clearing the NVRAM or loading new firmware).
During this operation, 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.
• Solid Red – indicates a fault condition with the receiver (no more
memory, no SD/MMC card inserted, a hardware problem, or an
improper OAF).
Table 1-2 on page 1-12 describes the REC LED status when using the
FN button.
The RX TX LED
displays the status of the modem. Table 1-1
describes the LED colors and patterns for the different modems
available for the HiPer Ga/Gb receiver.
