The most important button is the Answer/End call key, which is also used for last number redialing, voice dialing, and initiating the pairing process. In fact, the HF-200 can be paired with a total of eight devices, although it can only be connected with one at a time. The HF-200 hosts enough battery charge to handle 15 hours of talk time; plus, the device automatically turns off if not connected with a handset for over 5 minutes.
