I'm using a HTC Legend and would like to sync it
For some phones, provided that both its bluetooth radio and a nearby BT headset are turned on, and the headset's MFB (for the IS800, the only button it has) is briefly pressed. The phone then prompts the user to pair with the headset. For others, the headset must be put in pairing mode, and the phone must be made to search for it. If this is your case, press and hold the IS800's button until the right earpiece's led flashes red / green (the white led, next to the mic, will flash too). Then, you must start your phone's bluetooth settings, and make it search for the headset. In both cases, if you are prompted to enter a pairing code, the IS800's is '0000' (four zeros).
Hope you are able to sort your problems out.
