[Dtb-talk] NLS Digital Players

[Eric SS]

If this is off topic, forgive me.

I just received a player yesterday.  I have reviewed all instructions and
the built-in manual.

As I do not yet have a cartridge, I am reading with a USB thumb drive.

My question is should I be able to have more than one book on a drive?  When
I turn on the unit it tells me there are two books and the information
option confirms that, but I cannot jump out of the first book.

Many thanks!
