I have misplaced the manual for my lg tone platinum i cant remember what to do on the headset to pair it to my phone. cant you assist?

You can find the manuals here:

Just put in your model number. But to pair a device to your headset, you can do the following:

1) Easy Pairing a) Move the Power Switch to the "ON" position. b) If it is your first time paring the device it will automatically enter pairing mode. If it has been paired but no paired device is in range it will enter Pairing mode after 10 seconds.
• The LED indicator will be Solid Blue c) On the device you wish to pair, find the bluetooth menu and "serch for" or "add" new devices d) Select "LG HBS-700" From the list of devices e) If asked for a Pass/Pin Code enter 0000 (4 Zero's) f) Once pairing is complete you will hear a beep • The HBS-700 will automatically turn off if not paired within 3 minutes.

I hope the information posted helps!
