When I first got my ETEN M600 on the 31 Dec 2005, I did not find any button on it to lock the screen like the option to do a key lock on my Nokia 6510. I was frustrated. All I could then do was to press the ON/OFF button to put it into sleep mode. I did not want to accidently make phone calls on my ETEN M600.

Then I made a posting on the Eten Pocket User Forum and got my answer in less than 1 hour. Isnt that great about forums.

Here’s the step to lock the screen on your ETEN M600 pda phone:

tap SETTINGS->TODAY->ITEMS then check DEVICE LOCK option.
