Slide the COMMAND MODE switch on
the remote to select the command
mode (DVD 1, DVD 2, or DVD 3) so that
the setting for the remote differs from
the other DVD players.
For example, if other DVD players
respond to the default command mode
setting for the supplied remote (DVD 1),
set the remote to DVD 2 or DVD 3.
2
Slide the COMMAND MODE switch on
the rear of the player so it matches
that of the supplied remote.
