New Z90Q8 password not working

Greetings!

The newly purchased Z90Q8 client does not accept the default password Wyse#123. The included leaflet mentions administrative user as Administrator with password Wyse#123, however in this specific unit there are two users available for login: Admin (not administrator as it is mentioned in the leaflet and in online setup guide) and User. Neither accepts password Wyse#123. I'm really lost here. Does anybody can help?
