Troubleshooting
1) Do a ping test after connecting the network line which was used in the SET to a PC to check the network line itself.
2) Do a ping test after connecting the network line to the SET. If it is okay, check the network configuration which may
set wrong by some users without notice.
3) If the result of the ping test is not good, then open the rear cover and see the main board if there are some visible
defects on the network related components such as connector(CN16), capacitor(C192), and any other components
nearby. Surge voltage from the outside may cause the defects.
4) If those components have visible defects, then the main board should be changed.
