The entire upload process should take around five minutes to complete. If all the active
modules been upgraded successfully, the system will automatically reboot itself, and will
power up in normal operating mode with the new firmware.
If there is a problem with any stage of the upgrade, a warning message will appear on
the front panel display in the form "Step X failed" and the 4 LEDs will blink red. Power
cycle the system to clear this state and repeat steps 4 and 5. If after one or two attempts
this problem continues, contact Technical Support.
Step 6 - Verify the New Version
Verify that the correct version of firmware was loaded by going to the SYSINFO / VER
submenu on the front panel display. If the new version is correct, then the firmware
upload is complete. Repeat Steps 2-6 for all other receivers in your possession.
Once all receivers are upgraded, the firmware file can be deleted from the SD card, or
else saved as a backup. It is recommended to delete the firmware file from the SD card
after the firmware upload, however the receiver will operate properly if the firmware file
is left on the SD card.
