Hello my friend,in Idle mode, press and hold [#] to
activate or deactivate Quiet mode.

the chip of bluetooth works with the smal program on the cellphone.  there are two option. software or chip is broke down. should go to service.

Go to options and then profiles and put it on general. If that doesn't work, if your phone has a button to reduce and increase voume try that as well.Please give me a rating!

hold down the hash key

all u need to do is go to your standby screen and press and hold # it will say something in the line of "quite mode deactivated

puk code doesn't matter with the phone ( d900)...
this code is on the sim card that you are using not on the phone

I believe that pressing and holding in the hash key ( # ) turns on and off quiet mode

Press and hold down the # key for about 2 seconds, this is how you switch between Quiet mode and normal mode Regards
