scroll down the list.
16. Select the word "none" to make your unit
region free.
17. The warning you see is probably meant to
do nothing more than frighten you, I don't
think you can damage your player by altering
this since it's only altering region codes
, which have nothing to do with anything vital
to the unit. [no worse than changing TV channels
really].
18. press "i" to end.
I'm in Australia and bought my player locally, so it
appears that this probably works on all xenaro players.

1. Get into the Service Menu.
This is not intended for home users, only for
service technicians. Therefore you're asked for
an access code, it is 8500 for all Xenaro
DVD Players.
2. Activate "System Messages" using the Service Menu.
3. Leave the Service Menu and get into the "System
Informations" Menu.
4. When you see the System Infos, enter the following
code on the remote control. Note that the player
will not print the code on the screen, you have
to enter it blindly.
The code is: 70307192
(This is the one that differs from the 5100
model.)
5. A system message should appear. It will not appear
if you got the code wrong or if you did not
activate system messages in the service menu.
Confirm the message with OK on your remote.
6. Now a window appears in which you can change your
region code. Values 1 to 8 and "none" are possible.
"none" will disable the internal check of region
codes (i.e. makes the player CodeFree), but RCE
titles might not work. This doesn't really
matter, as you can change the code as often
as you wish to match a specific disc.
7. If you want to, you can disable System Messages
again using the Service Menu after you changed
the code.
