Sony MD Deck model MDS JB930 - Doesn't scroll track names

[DigitalSound]

Hello to all MD users.

I have a Sony MD deck model MDS JB930. It works ok, good sound quality, for play and to record from any source, analog or digital.

My request for your help goes to a functionality that i really don't know why it does not work...

When i put a pre-recorded MD and select play, both MD Title and track names appear scrolling on the MD text screen.

When i do that with an MD recorded by me in wicth i've put the MD Title and Track Names, using a PS2 Keyboard, it only scrolls automatically the MD Title, all Track names are stil, i have to select the button with the functionallyti "Scroll" in order to see the name for each track.

My question is: Does this deck model works this way by default or can i change anu parameters in order to "fix" this.

In the user manual i DO NOT see any info regarding this "problem" or who to fix it.

Thank you all in advance for your kind help.

Best regards,

DigitalSound.
