Clarion VZ401E, asks for pin ????

[Eskerra]

Hi, good afternoon to all.
I have one of these units with me, its a Clarion VZ401E, with flip out 7" touchable screen.
Units when power up, ask for pin.
Is there somehow, to reset it, or delete, or read ????

Thanks.
Regards.

What is written on touchable screen?
