3.2 UPDATING SYSTEM SOFTWARE
If the system software of the NF620
needs to be upgraded, please take the following steps to
safely process it.
Important: Before carrying out the following procedures, please ensure the SD card is
working and the file of the system firmware is intact
1. Format an SD card using the FAT16 format if it is unformatted; there are no limitations to an SD
card’s capacity.
2. Create a directory named LANCAM in the SD card if it does not exist.
3. Copy the file of UPDATE.BIN to the LANCAM-directory.
4. If the NF620 is running, please power it off first.
5. Insert the SD CARD into the NF620.
6. Remove the Ethernet cable from the RJ-45 port and then power on the NF620.
7. In 5 to 10 seconds, a message reading "UPDATE PROCESSING" will show up on the screen on
a blue background; if not, please check out steps 1 to 6 carefully or else inform your technical
support while ignoring the following steps.
8. DO NOT power off the NF620 while this update process is running until the message "UPDATE
OK RESET PLEASE" appears on the screen; it might take 15 to 30 seconds to appear.
9. If the message "UPDATE NG RESET PLEASE" appears rather than "UPDATE OK RESET
PLEASE", please write down the error messages shown on the screen and inform your
technical support, while ignoring the following steps.
10. Power off the NF620 when this update process is finished, then remove the SD card from the
NF620.
11. Reconnect the Ethernet cable to the RJ-45 port if necessary.
12. Power ON the NF620 and it will work normally if the entire update procedure goes correctly.
13. Verify the version of the system software.
