sanyo DWM370 region free code

folks

any ideas on the code for a sanyo dwm370 dvd player.

attempting to watch some region 2 dvds - tried this:

NO DISC INSIDE THE DVD PLAYER
USE ONLY THE REMOTE CONTROL
1) POWER ON
2) PRESS ON REMOTE 11233543254346
3) POWER OFF

POWER ON AND INSERT ANY REGION DISC
AND PLAY THEM ALL (ALL REGIONS)

but no joy

any other ideas would be most appreciated

cheers
