I don't know security setting password of my phone Q5fb

I don't know security setting password & i want to changed password of my phone which is Micromax Q5fb.

I searched internet to find reset code which can work on that phone but there was no help on even google. I searched for Manually reset Micromax mobile phone and hard reset mobile phone or even tried to search to factory reset code. There were many code I found but I can't apply as I can't dial number. It only says input unlock code.

How can I reset to default setting a Micromox q5 mobile ?
