Razrwire Bluetooth Eyewear - Frequently Asked Questions

What is Bluetooth®?
Bluetooth is a low power wireless technology designed for voice and data communications over short distances. Similar to some cordless phones, cellular phones, and the 802.11 WiFi technology, Bluetooth operates in the 2.4 GHz ISM band, providing license-free operation in the United States, Europe and Japan.

What is “pairing”?
Pairing is the process by which two Bluetooth devices identify each other. Pairing allows your cellular phone to remember the unique ID of RAZRWIRE, so that the two devices can communicate.

Do I need to go through the pairing process every time I use RAZRWIRE?
No, pairing is a one-time task. Once the two devices are “paired,” RAZRWIRE automatically connects to your cellphone when you turn RAZRWIRE on.

What version of Bluetooth does RAZRWIRE use?
RAZRWIRE uses the Bluetooth 1.2 standard. Note that products such as RAZRWIRE that support Bluetooth 1.2 are completely backward compatible with the Bluetooth 1.1 standard.

What is the difference between Bluetooth 1.1 and 1.2?
Bluetooth 1.2 includes several improvements over 1.1, including faster connection times, better audio performance and better resistance to interference from other wireless products.

With Bluetooth 1.2, an innovation called “quick connect” reduces the time it takes a Bluetooth device to search for other Bluetooth devices. The improvement also allows for faster pairing of devices. “Adaptive frequency hopping” enables Bluetooth products to work better in the presence of WiFi or other wireless technologies. The technology monitors the available channels and avoids those channels that are being used by other products. This improves connection quality and reduces “popping” and signal drop-outs of the Bluetooth channel.

Is RAZRWIRE compatible with every cellphone?
RAZRWIRE is compatible with most Bluetooth 1.1 and 1.2 enabled cellular phones only. Cellular phones that are Bluetooth 1.1 or 1.2 enabled and support either the Bluetooth Headset profile or the Bluetooth Handsfree profile are compatible with RAZRWIRE. Check the manual that came with your cellular phone to see if one of these Bluetooth profiles is supported.

What are Bluetooth “profiles”?
Working like the software drivers in a computer, a profile is the software put into devices to enable communication. Think of “Bluetooth” as the technology that creates the wireless connection between two devices; the “profile” is what allows them to understand and work with each other over the wireless connection. (To put it another way: If two people are communicating by mailing each other letters, the postal service is playing a role similar to Bluetooth. The written language that the two people are using is the profile they both understand, so it allows them to communicate.) Note that if two devices don’t share the same Bluetooth profile, they cannot communicate, even if both are “Bluetooth enabled.”
