2. Signals after inserting MicroSD card
After inserting the MicroSD card into the Device you will see a sequence of three flashes:
• Three green flashes:
the YDNG.TXT configuration file has been read and changes have been made
to the current Device settings and saved to non-volatile memory. The YDNGSAVE.TXT file
on the card has been saved with the updated configuration.
• Green, red, red:
the YDNG.TXT file has been read from the card, but the current configuration
of the Device has not been changed (either the configuration file does not differ from the current
settings, contains errors or there are no settings in the file). The YDNGSAVE.TXT file on the card
has been saved with the current configuration.
• Three red flashes:
the YDNG.TXT was not found on the MicroSD card or the file system
is not supported (see section III).
You can safely remove the MicroSD card when the flash sequence is finished.
3. Other signals
LED signals during diagnostics recording and during firmware updates are described in Sections VII
and VIII.
