Software Recovery By Modem
In case of main machine software in the master board soft-
ware is corrupted or missing, if the modem contains the
main machine software it is able to install the software in
the master board.
When the modem installs the main machine software on
the master board, the first part of the installing process is
the erasing of the eventual software on master board, so
that the remote control display will show wrong images.
While the installing process is in progress the machine
must been left switched on for 10-15 minutes, till the
ground green light comes on flashing.
