The pairing mode in this headset is indicated by its light steadily light. Starting with it turned off, if it has never been paired before, just by turning it on, it should enter the pairing mode automatically. Otherwise, press and hold the Multi-Function Button for a longer time than the time required to turnit on, until the indicator light is steadily lit. Only then, make your phone's bluetooth application search for new devices. After a little while, the WEP350 should appear on the phone' screen. Select it and make it connect. If a pairing code (or PIN, or passkey) is requested, enter '0000' (four zeros).
By the way, if your headset's user guide happens to be missing, feel free to download it from
this location.
Plase, let me know if I can help you any further.
