Bluetooth Was given a used motorola bluetooth for my phone. I figured out how to connect, but how about disconneting when I want to use the phone. This came with no insturctions and I'm a little electronically challanged

Try power cycling the phone. Turn the Nokia off, wait 10 seconds, then turn back on and try again. It really does help sometimes. Let us know if this doesn't help.

just get your bluetooth in pairing mode (steady blue light) then have your phone find the device then connect them when they ask you for the pass code its 0000 if your bluetooth is connected to a different phone you must disconnect it and if it doesnt work and you tried your best try turning the phone off then try it again sometimes this does the trick

this is for w376 and w377 user guide

in the phone itself, you have to search for bluetooth devices and accept the found device in order for it to work, once set-up searching is not needed for that device again

1.Press and hold the Multifunction button in the middle of a boom headset while the headset is closed. The light will glow blue.2.Open the boom microphone and the blue light should remain on. If not, repeat step 1.
3.On the cell phone, press Menu > Settings > Connection > Bluetooth > Handsfree > New Device
4.Select H300 once a connection is detected.
5.The passkey "0000" is now entered to confirm the connection has been made.
6.The cell phone screen will now read "Bluetooth Connection".

Tips:
1.Provided you set the Bluetooth power to "On" after the initial connection has been made, the phone will automatically re-connect to the headset.
2.To set the Bluetooth power on - Press Menu, Select Settings, then Connections, then Bluetooth link, scroll to Setup and select that. Scroll to Power and chose Change. Scroll to On and press Select. The screen should now read "Changed: Power On".
3.Test Your Connection: Close the headset and watch for cell phone to say "Disconnected". Re-open the headset and the phone should be connected automatically and will now display "Bluetooth Connected".

please give good rating if the solution works.

I used this Motorola Bluetooth manual to connect my Motorola N136/HS 850 to my LG PM 325 phone. In the attached manual: Go to "using your headset" - "linking your headset and phone" and follow the instructions. You may need to revise the steps slightly to fit the functions of your phone. I followed steps 1 and 2, skipped step 3 and instead found the bluetooth icon on my phone, selected "add new", then selected "searching and pairing" and allowed the phone to search for and pair my bluetooth device. The Motorola Bluetooth device appeared on the screen of my phone within seconds as "Motorola HS850". I selected the device on the screen of my phone and followed step 5 entering the pin code "0000" and selected "connect" on my phone to begin using my bluetooth. I hope this helps someone.

do you want to connect through data cable or bluetooth .......

for data cable just connect your mobile to pc and install the cd given to that particular model and transfer the data

for bluetooth ensure that the blurtooth is turned on in both pc and phone to transfer data

when it asked for the pincode to paired the bluetooth headset enter the code 0000

Bluetooth doesn't shut off on its own unless you turn off your phone. In the bluetooth options, you should be able to select "Turning Bluetooth On", "Turning Bluetooth Off", or "Using Discovery Mode (60 seconds)." Discovery Mode, which I believe is what your using, is only used when connecting to another device. My question for you is, what kind of device are you trying to connect to?

On the following link you will find a very useful pairing guide that will take you through the setup. http://www.motorola.com/consumer/v/index.jsp?vgnextoid=38b5f7c0c1a0b010VgnVCM1000008206b00aRCRD&ps=y&pg=PG_TYP_00003&show=globalSupport&productID=fd13e7af976c9010VgnVCM1000008206b00aRCRD Please update the question & let us know if the information given was useful to you - Good Luck!
