What is Bluetooth?
Bluetooth is the name for a short-range radio frequency (RF) technology that operates at 2.4 GHz and is capable of transmitting voice and data. The effective range of Bluetooth devices is 32 feet (10 meters). Bluetooth version 1.2 transfers data at the rate of 1 Mbps, and Bluetooth Version 2.0 transfers data at the rate of 3 Mbps.
Why is the technology called Bluetooth?
The heart of the Bluetooth brand identity is the name, which refers to the Danish king Harald "Bluetooth" Blaatand who unified Denmark and Norway. In the beginning of the Bluetooth wireless technology era, Bluetooth was aimed at unifying the telecom and computing industries.
How is Bluetooth used?
Bluetooth can be used to wirelessly synchronize and transfer data among devices. Bluetooth can be thought of as a cable replacement technology. Typical uses include hands-free devices, automatically synchronizing contact and calendar information among desktop, notebook and palmtop computers without connecting cables. Bluetooth can also be used to access a network or the Internet with a notebook computer by connecting wirelessly to a cellular phone
Are different brands of Bluetooth products compatible?
Yes. They have to. The Bluetooth Logo Certification Program requires Bluetooth products to interoperate with products manufactured by other vendors; those products that don't interoperate will not be allowed to use the Bluetooth logo.
What companies are involved in the Bluetooth initiative?
Global technology leaders Ericsson, Nokia, IBM, Intel and Toshiba founded the Bluetooth SIG in 1998. These companies are now supported by over 1,000 other organizations with a wide range of expertise.

Is my phone compatible?
If your cell phone has Bluetooth enabled, it is more than likely compatible with our devices. However, some functions such as voice dialing is dependent on whether or not your cell phone supports the function
Which mobile phone carriers sell Bluetooth enabled phones?
Bluetooth phones are available from mobile network operators worldwide. However, not all network operators currently sell Bluetooth enabled phones. Due to the rate at which mobile operators change their phone offerings, we are unable to provide an up-to-date list of phones available at each operator worldwide. Please contact your local mobile operator to see if it offers Bluetooth enabled mobile phones.
My new vehicle has a Bluetooth system; do I still need your product?
Yes, the system in your new vehicle is limited to that vehicle only. Our portable devices can be used in any vehicles such as other family or company vehicles, rental cars, etc. You can take these portable devices anywhere. You can also purchase these portable devices for gifts and keep the entire family safe.
Why can't I pair my device & my phone?
Please make sure that both the device and your cell phone has sufficient power, and that the Bluetooth device is in pairing mode. It is recommended that you fully charge the device and your cell phone before attempting to pair the first time. The device must be in pairing mode before you cell phone can "search" for the device
.
What is TTS?
Text-to-Speech is an artificial production of human speech. A TTS system converts normal language text into speech. NoHands currently offers some Bluetooth devices that have TTS capability. This enables the device to call out the incoming caller's phone number or if the phonebook has been successfully been transfered to the device it could call out the Caller's name as is stored on the phonebook log.

What is the difference between Bluetooth version 2.0 and version 1.2?
Bluetooth version 2.0 compared to its predecessors has the following advantages:
This version is backwards compatible, which means it is able to take the place of an older version, with versions 1.1 or 1.2. Version 2.0 includes the new Enhanced Data Rate (EDR) of 3.0 Mbps.
- Faster - 3 times faster transmission speed, up to 10 times in certain cases
- Longer battery life - Lower power consumption through a reduced duty cycle
- Device can pair with multiple phones - Simplification of multi-link scenarios due to more available bandwidth
- Clear Calls - Improved Bit Error Rate (BER) performance.
My phone disconnects sometimes. What can I do?
On certain phones, it is normal. It depends on the Bluetooth profile of the phone. There are 2 bluetooth profiles for phones: Headset profile and HandsFree profile. HeadSet profile is the more basic profile. Your phone and the car kit don't need to be always connected all the time. They only connect to each other when they need to exchange data during the calls. HandsFree profile is the more elaborate profile. Your phone and the kit are always connected together. In order to check which profile your phone supports, please refer to the phone user manual.
