How to unlock MP4 player after the lock comes on?

[gloves]

hi,
please can anybody help me . i bought one of these fake i pod nano's of ebay and although i wasn't expecting too much, the instructions i got were rubbish. i have sorted out most things but can't seem to suss out how to unlock it after the lock comes on through it being idle for about a minute. the only way i can do anything again, is by switching the player off and back on again.

the firmware on my player is
MP4 PLAYER
CBD CO. ,LTD
2009-10-05
9.5.54

any help or better instructions on how to use would be appreciated.
thanx
