My sony VH300 bluetooth headset has a problem. The connection is not consistent & I keep losing connection with my phone. If i shake the headset, the connection comes back but does not remain for long. The phone is barely kept 1 metre away from the headset. The person on the other end can hear me as my voice gets transmitted but his voice comes in breaking & I have to keep readjusting the headset's position regulalry. Please help.

Bluetooth wireless signal can be blocked by your body and even by your head. Try orienting yourself so that the audio source is directly in line with the bluetooth antenna in the headset.

I think you should ask Sony Ericssion for help.

Android 4.0 Tablet PC

Accessory instructions: VH300 Before you can use your Bluetooth

Be sure the the headset in in 'Pairing' mode.
When in pairing mode, the light should be flashing red and blue or have a steady blue.
The put most headsets in pairing mode, turn headset OFF, then hold the power button until it goes into pairing mode as discribed above.
Then you can discover it with your phone or PC. Pin (pass key) should be 0000 (4 Zeros) or try 1111, 1234, 9999

I had similiar problem with my sony ericsson w890i. Solution was to switch headset off, turn on and keep the button pressed down while searching for new devices on phone.

I had lots of trouble too. I thought it was my phone. Well here's what you do. First off remove the device completely from your phone. Turn off the phone and take the battery off so it can re-boot. When the phone is powered back up put your bluetooth in pairing mode and get it back on your phone. It should connect without any problems. Now....here is the trick. When you want to disconnect the device(bluetooth) from your phone don't turn it off on your phone. Shut the actual power off on your bluetooth. The phone will recognize this and disconnect the device. The only thing left on your phone will be the bluetooth icon. Being the icon still on your phone it is still in discovery mode and can overtime use up your battery life searching for a device. This is when you can go to your phone and turn off the bluetooth. On your NV 2 go to your bluetooth menu and just use your left softkeyto turn it off. Now there is no connection whatsoever. And to turn it back on do the opposite. Go to your bluetooth menu and turn on your bluetooth. You will see the bluetooth icon. Now you power up the bluetooth and it will connect as soon as it get the signal. This took me 2 weeks of trial and error and other stuff but I am happy now and I hope this solves any bluetooth problems...

In the Connectivity menu, you can change your phone connectivity settings. You can turn Bluetooth™ and IR on or off, change the default mode for your phone when connected via USB hope this wrks..All the best

Happy to help
Have a nice day!

Sorry but what do you mean by?:- 'The car unit will not allow me to use the colour previously used' It should be the phone with the memory and the search facility for finding your car headset device, not the device looking for the phone. Once you have searched for new devices and found the headset with a different phone, the headset will not be able to connect with more than one device and should lose the old phone connection.
